How Jada Pinkett Smith Keeps Her Love Life Hot

FitSugar — Tue, 14 Jul 2009 04:30:59 -0700

Jada Pinkett Smith is no stranger to sharing details about her love life; with 12 years of a successful Hollywood marriage under her belt, she probably has some healthy secrets we could all use. She told Shape magazine that she is a firm believer in kegels. Pinkett Smith proclaims doing these simple pelvic floor exercises "keeps the sex hot."

If you practice yoga, you might refer to the pelvic floor (PF) as the mula bandha. The easiest way to find the correct area to activate is to stop the flow of urine when emptying your bladder. Then try to find that same sensation when not going to the restroom. A little more advanced variation is to create the sensation of the entire pelvic floor pulling up. The muscles of the pelvic floor fill in the space between your pubic bone (front of your pelvis), your coccyx (tail bone), and your sit bones (ischial tuberosities in anatomy lingo). The overall shape is similar to a kite and contains many different muscles. To activate the pelvic floor you want to imagine those aforementioned bones coming closer to one another as the muscles attached to them activate and pull up - like a sheet being held by four corners billowing up as the corners move toward the center. It helps to think of the PF as similar to your diaphragm, which moves up and down as you inhale and exhale.

Here is a subtle and simple exercise that you can do right now. It is so subtle that no one will know you are exercising your nether regions. On a four-count inhale, pull the PF up and in toward the center line of your body. Then release slowly on a four-count exhale. Allow your pelvic floor to completely relax in between repetitions. Repeat five to 10 times and throughout the day. Aside from beneficial side effects in the bedroom, a strong pelvic floor provides support while running and lifting weights too. After all, it is part of your core.

Yep, Down There: Strengthening Your Pelvic Floor

No one ever brags about how hard they worked their pelvic floor. It just sounds a wee bit smutty. These often neglected, little muscles that support your torso from the base of your pelvis need to be demystified so you can strengthen them correctly; since they are considered an important component of your core.

If you practice yoga you might refer to the pelvic floor (PF) as the mula bandha. Most ladies work their PF by doing kegels, but that just works a portion of the muscles and doesn't necessarily help pull the PF up. The muscles of the pelvic floor fill in the space between your pubic bone (front of your pelvis), your coccyx (tail bone), and your sits bones (ischial tuberosites in anatomy lingo). The overall shape is similar to a kite and contains many different muscles. To activate the pelvic floor you want to imagine those above mentioned bones coming closer to one another as the muscles attached to them activate and pull up. It helps to think of the PF as similar to your diaphragm that moves up and down as you inhale and exhale.

Fit's Tip: This exercise isn't just for postpartum mamas. Nope - it is great for everybody since it helps create a stable base for motion. Aside from providing support while running and lifting weights, a toned pelvic floor provides beneficial side effects in the bedroom, too! I actually had husbands of my Pilates clients thank me for teaching their wives this exercise.

Core Questions

FitSugar — Fri, 10 Nov 2006 02:30:00 -0800

No doubt you have heard the term "core" tossed about they gym. You know it's deep, but you have some core questions.

Core question - What is it?

The Core is a group of muscles made up of:

The tranversus abdominis (don’t be intimidated by the Latin) a.k.a the deep abdominal muscle that wraps around your torso. It is the deepest of the abs, and it acts like a natural weight-lifting belt.
The multifidi – a group of deep spinal muscles that stabilize the spine and prevent excessive rotation of the vertebrae.
The pelvic floor– yep, down there. The pelvic floor is a few layers of muscles that connect your pubic bone, tail bone and sits bones.

Core question – What does it do?
When these groups of muscles work together they stabilize the torso, pelvis and spine.

Have a few more core questions? Then read more

Core question – How do I feel my core?
Imagine sandwiching your spine with your deep abs and deep spinal muscles while pulling your pelvic floor up (like doing a kagel with a lift).

Core question – How do I strengthen my core?
You want to feel the core engage as you exhale during the strenuous part of an exercise. When lifting weights, exhale and feel your core, then lift. Your torso should stay stable – that’s how you know your working it.

Core question - Why is it important?
It stabilizes your pelvis and low back, helping to prevent injury. It also makes for a flat belly.

Is Running While Pregnant Safe?

FitSugar — Tue, 20 Oct 2009 08:00:52 -0700

It's not every day that you see a pregnant woman going for a run, like Miss Kourtney Kardashian here. On her hour-long jog, I'm sure she got some stares and whispers. Not just because she's famous, but because she's got a big bun in the oven. They're probably wondering, is this safe for her baby, and safe for mom?

Regular exercise is encouraged by doctors for those expecting, because it can help a woman stay healthy, and alleviate some of the discomforts like stiffness, back pain, leg cramping, or constipation. Working out can also prevent unnecessary weight gain, relieve stress, and get a woman ready to endure the physical challenges of labor.

With that said, there are some guidelines a pregnant woman should follow when working out.

Don't make any big changes to your exercise program once you become pregnant. If you were running regularly before you conceived, then it's safe to keep it up, as long as it feels good and you don't overdo it. If you want to start a new type of exercise, talk to your doc first.
Be OK with modifying your routine, especially as your pregnancy progresses. If you used to run four miles a day, you may find that you'll need to cut down in the beginning of your pregnancy. And once you're in the end of your second trimester, or third, walking may be best.
Don't do any types of exercise that put you or the baby at risk, like extreme sports that require balance, speed, or could result in you falling. Your doctor will probably recommend you save the surfing, skiing, horseback riding, biking outdoors, and rock climbing for after delivery.

Sling Procedure Versus Burch Colposuspension

The sling procedure is better than Burch colposuspension in treating stress incontinence but may cause more post-operative urinary complications, according to results from an important 2007 New England Journal of Medicine study. In the first large-scale clinical trial to directly compare these two types of surgery, 47% of women who underwent the sling procedure had no urinary incontinence 2 years after surgery, compared with 38% of women who received the Burch procedure. However, 63% of women who had the sling procedure (and 47% of women who underwent the Burch procedure) experienced urinary tract infections following surgery.

Oxybutynin May Cause Hallucinations

In 2007, the FDA investigated reports that oxybutynin (Detrol) may cause hallucinations, especially in children and older adults. Out of 202 reports of oxybutynin-related central nervous system side effects, hallucinations occurred in 27% of cases involving children and 25% of cases involving adults age 60 years and older. The FDA is considering adding stronger cautions about these risks to oxybutynin’s prescribing label.

Tamsulosin and Tolterodine Combination Treatment

For men with moderate-to-severe lower urinary tract symptoms, including overactive bladder, a combination of tamsulosin (Flomax) and tolterodine (Detrol) works better than either drug alone, according to a study published in 2006 in the Journal of the American Medical Association.

Researchers Investigating Stem Cell Treatment for Stress Incontinence

Muscle stem cell injections may eventually prove to be an effective treatment for stress incontinence, indicate several small studies. Doctors took tissue biopsies from patients’ arm muscles, then isolated and injected the muscle stem cells into areas surrounding the urethra. The injections helped strengthen sphincter muscles and improved bladder control. Researchers presented results of these studies at the 2007 American Urological Association annual meeting and the 2006 Radiological Society of North America annual meeting.

Introduction

Urinary incontinence is the inability to control urination. It may be temporary or permanent, and can result from a variety of problems in the urinary tract. Urinary incontinence is generally divided into four groups, according to the problem involved:

Stress incontinence
Urge incontinence
Overflow incontinence
Functional incontinence

Often, more than one type of incontinence is present, with about 40% of all cases falling into more than one category.

Because incontinence is a symptom, rather than a disease, it is often hard to determine the cause. In addition, a variety of conditions may be the cause.

The urinary system helps to maintain proper water and salt balance throughout the body:

The process of urination begins in the two kidneys, which process fluids and dissolve waste matter to produce urine.
Urine flows out of the kidneys into the bladder through two long tubes called ureters.
The bladder is a sac that acts as a reservoir for urine. It is covered with a membrane and enclosed in a powerful muscle called the detrusor. The bladder rests on top of the pelvic floor. This is a muscular structure similar to a sling running between the pubic bone in front to the base of the spine.
The bladder stores the urine until it is eliminated from the body via a tube called the urethra, which is the lowest part of the urinary tract. (In men it is enclosed in the penis. In women it leads directly out.)
The connection between the bladder and the urethra is called the bladder neck. Strong muscles called sphincter muscles encircle the bladder neck (the smooth internal sphincter muscles) and urethra (the fibrous external sphincter muscles).

The Process of Urination

The process of urination is a combination of automatic and conscious muscle actions. There are two phases: the emptying phase and the filling and storage phase.

The Filling and Storage Phase. When a person has completed urination, the bladder is empty. This triggers the filling and storage phase, which includes both automatic and conscious actions.

Automatic Actions. The automatic signaling process in the brain relies on a pathway of nerve cells and chemical messengers (neurotransmitters) called the cholinergic and adrenergic systems. Important neurotransmitters include serotonin and noradrenaline. This pathway signals the detrusor muscle surrounding the bladder to relax. As the muscles relax, the bladder expands and allows urine to flow into it from the kidney. As the bladder fills to its capacity (about 8 - 16 oz of fluid) the nerves in the bladder send back signals of fullness to the spinal cord and the brain.
Conscious Actions. As the bladder swells, the person becomes conscious of a sensation of fullness. In response, the individual holds the urine back by voluntarily contracting the external sphincter muscles, the muscle group surrounding the urethra. These are the muscles that children learn to control during the toilet training process.

When the need to urinate becomes greater than one's ability to control it, urination (the emptying phase) begins.

The Emptying Phase. This phase also involves automatic and conscious actions.

Automatic Actions. When a person is ready to urinate, the nervous system initiates the voiding reflex. The nerves in the spinal cord (not the brain) signal the detrusor muscles to contract. At the same time, nerves are also telling the involuntary internal sphincter (a strong muscle encircling the bladder neck) to relax. With the bladder neck now open, the urine flows out of the bladder into the urethra.
Conscious Actions. Once the urine enters the urethra, a person consciously relaxes the external sphincter muscles, which allows urine to completely drain out from the bladder.

The female and male urinary tracts are relatively the same except for the length of the urethra.

Stress Incontinence

The primary symptom of stress incontinence is leakage due to activities that apply pressure to a full bladder. High-impact exercise poses the greatest risk for leaking. But stress incontinence can occur with even minor activities, such as:

Coughing
Sneezing
Laughing
Running (sometimes even standing can produce leakage)
Lifting

Leakage stops when the activity stops. If the condition persists, it is more likely to be urge incontinence.

Stress incontinence occurs because the internal sphincter does not close completely. In both men and women, the aging process causes a general weakening of the sphincter muscles and a decrease in bladder capacity. Causes of stress incontinence, however, may differ between men and women.

In women, stress incontinence is nearly always due to one or both of the following:

The urethra fails to close and becomes overly movable (urethral hypermobility).
The muscles around the bladder neck weaken (intrinsic sphincteric deficiency or ISD). Some experts believe that this problem is present to some degree in nearly all women with stress incontinence. (ISD can also occur in anyone from an inborn disorder or injury from surgery or radiation.)

Many women are prone to one or both of these problems, which can occur under the following circumstances:

Having had many children through vaginal deliveries. In such cases, pregnancy and childbirth strain the muscles of the pelvic floor. Prolapsed uterus, in which the uterus protrudes into the vagina, occurs in about half of all women who have given birth. This condition can often cause incontinence.
Menopause. Estrogen deficiencies after menopause can cause the urethra to thin out so that it may not close properly.

Urethral Hypermobility. In urethral hypermobility the urethra does not close properly, allowing it to move too much (hypermobile). This condition typically occurs when the pelvic floor muscles in women become weak, and the following events occur:

The weakened pelvic floor muscles stretch.
This allows the bladder to sag downward within the abdomen.
The sagging bladder pulls on the muscles surrounding the bladder neck (internal sphincter), which are connected to the urethra.

Stress incontinence associated with urethral hypermobility is sometimes categorized as type 1 or type 2.

Type 1 is the less severe form, and the bladder neck and urethra remain incompletely closed.
In type 2, the angle of the bladder neck shifts. In such cases cystocele may occur, in which the bladder muscles bulge (herniate) into the vaginal wall.

Intrinsic sphincteric deficiency (ISD). Intrinsic sphincter deficiency (sometimes called type 3) is the other major cause of stress incontinence in women. It occurs when the bladder neck muscles are damaged or weakened. The result is twofold:

The bladder neck is open during filling.
The closing pressure around the urethra is low.

This is the most severe stress incontinence in women and usually occurs after previous surgeries for incontinence.

Prostate treatments can impair the sphincter muscles. Such treatments are the major causes of stress incontinence in men. They include the following:

Surgery or radiation for prostate cancer. Incontinence occurs in nearly all male patients for the first 3 - 6 months after radical prostatectomy. After a year of the procedure, most men retain continence, although leakage can occur.

Surgery for benign prostatic hyperplasia. Stress incontinence occurs in 1 - 5% of men after transurethral resection of the prostate (TURP), the standard treatment for severe benign prostatic hyperplasia.

Click the icon to see an illustrated series detailing TURP surgery.

Incontinence after prostate procedures is often a combination of urge and stress. Because studies often combine the two types of incontinence, it is not always clear which predominates.

Urge Incontinence

The main symptom of urge incontinence (also called hyperactive, irritable, or overactive bladder) is the need to urinate frequently. Patients may go to the bathroom more than 8 times over 24 hours, including 2 or more times a night, and have subsequent leakage. However, most people (60%) with overactive bladder experience only urgency and frequency. In some cases, urge incontinence occurs only at night. This is called nocturnal enuresis.

All cases of urge incontinence involve an overactive bladder. This occurs when the detrusor muscle, which surrounds the bladder, contracts inappropriately during the filling stage. When this occurs, the urge to urinate cannot be voluntarily suppressed, even temporarily. There is usually one of two types:

Idiopathic Detrusor Overactivity (formerly called Detrusor Instability). In this type, the nerves serving the bladder have signaled the brain appropriately that the bladder is full, but the detrusor muscles are unable to be suppressed. The actual cause, however, is not known.
Neurogenic Detrusor Overactivity (formerly called Detrusor Hyperreflexia). With this type, a known neurologic abnormality impairs the signaling systems between the bladder and the central nervous system, and the brain is unable to inhibit the detrusor muscles controlling urination.

Very often, the cause of detrusor instability and bladder hyperactivity is unknown. Some conditions that can produce the disorders leading to urge incontinence include the following:

Benign prostatic hyperplasia (BPH). Detrusor instability occurs in about 75% of men with BPH and causes frequency, urgency, and urination during the night (although incontinence itself occurs only in very severe cases). Urge incontinence only at night can be a sign of severe obstruction in the urinary tract.

Benign prostatic hypertrophy (BPH) is a non-cancerous enlargement of the prostate gland, commonly found in men over the age of 50.

Prostate surgical procedures. Either prostatectomy for prostate cancer or transurethral resection of the prostate (TURP) for BPH can cause detrusor instability. As with stress incontinence, prostatectomy poses a much higher rate than with TURP, which is very low.
Hysterectomy. Complications of this operation, which removes the uterus, are associated with a higher risk for urge incontinence. In one study, for example, incontinence developed or worsened after hysterectomy in about 16% of women who had only mild or no incontinence before surgery. However, hysterectomies can also significantly improve urinary incontinence in many women who have an existing condition before the procedure. In the same study, 30% of women had severe urinary incontinence before hysterectomy, which declined to 20% afterward and was sustained for at least 2 years.

Damage to the central nervous system. Certain neurologic disorders or injuries can disrupt the passage of nerve messages between the urinary tract and central nervous system. These neurological conditions include stroke, multiple sclerosis, spinal cord or disk injury, and Parkinson's disease.
Infections.
The aging process.
Emotional disorders. Anxiety and possibly even depression have been associated with urge incontinence.
Medications, including some sleeping pills.
Genetic factors may play a role in some cases.

Overflow Incontinence

Overflow incontinence happens when the normal flow of urine is blocked and the bladder cannot empty completely. Overflow incontinence can be due to a number of conditions:

A partial obstruction. In this case the urine cannot flow completely out of the bladder, so it never fully empties.
An inactive bladder muscle. In contrast to urge incontinence, the bladder is less active than normal, not more. It cannot empty properly and so becomes distended, or swells. Eventually this distention stretches the internal sphincter until it opens partially and leakage occurs.

The causes of the conditions leading to overflow incontinence include:

Tumors
Certain medications (anticholinergics, antidepressants, antipsychotics, sedatives, narcotics, alpha-adrenergic agonists, beta-adrenergic agonists, calcium channel blockers)
Benign prostatic hyperplasia (enlarged prostate)
Scar tissue
Nerve damage. In such cases, nerves in the bladder are damaged so that the body cannot feel when the bladder is full, and the bladder does not contract. Such damage can be caused by spinal cord injuries, previous surgery in the colon or rectum, and pelvic fractures. Diabetes, multiple sclerosis, and shingles also can cause this problem.

Functional Incontinence

Patients with functional incontinence have mental or physical disabilities that keep them from urinating, although the urinary system itself is normal. Conditions that can lead to function incontinence include:

Parkinson's disease.
Alzheimer's disease and other forms of dementia. Mental confusion may prevent both recognition of the need to void and locating a bathroom.
Severe depression. In such cases, people may become incontinent because they are indifferent to self-control.

Risk Factors

About 13 million adults experience incontinence at some time. The number, however, may actually be higher because most patients are reluctant to discuss incontinence with their doctors. In fact, research indicates that many patients will not admit to having the problem even when questioned directly. Although a third of American men and women age 30 - 70 have experienced at least some loss of bladder control, most have not been diagnosed by a doctor.

A 2004 survey of more than 1,400 Americans found that despite the prevalence of bladder control loss, an alarming 64% of those experiencing symptoms are not currently taking measures to manage their condition. The survey, sponsored by the National Association for Continence, also found that adults waited an average of 6 years before discussing their symptoms with a doctor. A 2006 study reported that only half of women with urinary incontinence have discussed their condition with a doctor, while only a third had received any treatment.

Incontinence is uncommon in children 5 years and older. However, it may still occur in:

10% of 5 year-olds
5% of 10 year-olds
1% of 18 year-olds

Incontinence that occurs before puberty is twice as common in boys as in girls. Most young people who experience nighttime wetting do not have any serious physical or emotional disorders. It is often difficult to diagnose incontinence in children. Many cases result from a combination of factors, including:

Birth defects or inborn conditions that cause problems in the urinary tract
Slower physical development
An overproduction of urine at night
A lack of ability to recognize bladder filling when asleep
Anxiety
Inherited factors (indicated by a strong family history of bedwetting)

Bedwetting in children is not considered incontinence. However, bedwetting and other urinary problems in childhood may predict the later development of adult urinary incontinence. According to a 2006 study, women who experienced childhood bedwetting, as well as frequent daytime and nighttime urination, had an increased risk of developing adult urge incontinence.

All older adults are susceptible to incontinence. One in 10 people over age 65 have some type of bladder control loss. About 12% of women ages 60 - 64 and 21% of women age 85 and over experience daily urinary incontinence. About half of the elderly who are housebound or in nursing homes experience incontinence.

Urinary incontinence is far more common among women than men. Between 15 - 50% of women experience urinary incontinence during their lifetimes, with the highest rates occurring in women who have had children. Severe urinary continence affects 7 – 10% of women. About 10% of women undergo surgery for urinary incontinence or pelvic organ prolapse.

Birth Conditions. Pregnancy and childbirth may increase the risk for urinary incontinence. The risk is highest with the first child, and there is an increased risk in women who have their first child over age 30. Some studies suggest that women who used the drug oxytocin for inducing labor are at higher risk for developing urinary incontinence. Such medically induced labor tends to subject the muscles and nerves in the pelvis to greater force than does natural labor.

Studies indicate that the method of birth can affect risk later in life. For example, a major 2003 study reported that women who had a cesarean section had a much lower risk for stress incontinence before age 50 than women who had vaginal delivery. However, a 2006 study contradicted many assumptions by suggesting that vaginal delivery is not associated with later development of urinary incontinence in postmenopausal women. The study compared sisters who had either given birth vaginally or had never had children. Researchers found no difference in rates of urinary incontinence. The study suggested that cesarean delivery may not make much difference in preventing urinary incontinence.

Another 2006 study found that episiotomy does not help prevent urinary incontinence. Episiotomy is a surgical incision that is made during childbirth to the perineum, the muscle between the vagina and the rectum. Doctors commonly perform this procedure to help widen the vaginal opening and prevent tearing. The study found that episiotomy does not have many benefits, and may later cause pain during intercourse.

Vaginal birth can cause pelvic prolapse, a condition in which pelvic muscles weaken and the pelvic organs (bladder, uterus) slip into the vaginal canal. Pelvic prolapse, and the surgery used to correct it, can cause incontinence. Sacrocolpopexy is the standard surgical procedure for repairing pelvic prolapse. A 2006 study found that performing a urinary incontinence surgical procedure (Burch colposuspension) at the same time as sacrocolpopexy can help prevent stress incontinence. [See Surgery section.]

High-Impact Exercise. Women who engage in high-impact exercise are susceptible to urinary leakage, particularly women with a low foot arch. Shock to the pelvic area is increased as the foot makes impact with hard surfaces. Those at highest risk for urinary leakage are gymnasts, followed by softball, volleyball, and basketball players.

Smokers. Studies have reported a higher risk for incontinence, notably mixed incontinence, in women who are current or former heavy smokers (more than a pack a day).

Obesity. Being overweight is a major risk factor for all types of incontinence. The more a woman weighs, the greater her risk.

Medical Factors in Older Women. Urge incontinence is more common among postmenopausal women who have a history of:

Diabetes
Higher body mass index (heavier weight)
Hysterectomy
Two or more urinary tract infections within the past year

The rate of incontinence in men (about 1.5 - 5%) is much lower than in women. The risk for urinary incontinence increases with age. In the United States, about 17% of men over age 60 have urinary incontinence. In older men, prostate problems and their treatments are the most common factors that affect the urinary tract. Up to 30% of men who have had surgery to remove their prostate gland experience some degree of urinary incontinence.

Urinary incontinence varies by race and ethnicity. It is most common in non-Hispanic white women. Among men, African-Americans are at highest risk. Some studies suggest that the greatest disparity is with stress incontinence. African-American and Asian American women have a much lower risk for stress incontinence than Caucasian and Hispanic women.

A number of conditions can cause temporary incontinence in anyone:

Urinary tract infections
Excess fluid intake
Constipation
Severe depression
Restricted mobility

Drugs. Drugs are most often the cause of temporary incontinence.

Drugs that affect the adrenergic system (a nerve-cell and hormonal pathway that regulates the sphincter muscle) are common causes of incontinence. For example, alpha-adrenergic blockers, such as terazosin (Hytrin), used for benign prostatic hypertrophy, can cause incontinence by over-relaxing the muscles. On the other hand, men with enlarged prostates who suffer from urinary problems may be helped by the increase of urine flow after using terazosin.
Alpha-adrenergic agonists, such as pseudoephedrine (found in some oral decongestants) strengthen the muscles and may cause overflow incontinence in susceptible people.
Beta-adrenergic blockers, such as propranolol (Inderal), prescribed for hypertension and angina, relax the sphincter.
Diuretics, used for high blood pressure, often rapidly introduce high urine volumes into the bladder.
Calcium-channel blockers can cause overflow incontinence by relaxing the bladder detrusor muscles.
Colchicine, a drug used for gout, can cause urge incontinence.
Other medications and substances that increase the risk for incontinence are caffeine, sedatives, antidepressants, antipsychotics, and antihistamines.

Diagnosis

Fewer than half of the patients who have urinary incontinence tell their doctor about the problem. In many cases, patients simply feel that incontinence is part of the aging process. And, in spite of the commonness of this problem, two-thirds of doctors never ask their older patients if they experience incontinence.

It is important, however, for both the doctor and the patient to raise the issue.

The first step in the diagnosis of incontinence is a detailed history. The doctor should ask questions about the patient's present and past medical conditions and patterns of urination. Patients should tell the doctor the following information:

When the problem began
Frequency of urination
Amount of daily fluid intake
Use of caffeine or alcohol
Frequency and description of leakage or urine loss, including activity at the time, sensation of urge to urinate, and approximate volume of urine lost
Frequency of urination during the night
Whether the bladder feels empty after urinating
Pain or burning during urination
Problems starting or stopping the flow of urine
Forcefulness of the urine stream
Presence of blood, unusual odor or color in the urine
A list of major surgeries with their dates, including pregnancies and deliveries, and other medical conditions
Any medications being taken

A 2006 study suggested a simpler way of diagnosing incontinence using a test that asks 3 questions:

During the last 3 months, have you leaked urine (even a small amount)?
When did you leak urine? (During physical activity; when you could not reach the bathroom quickly enough; without physical activity or bladder urge.)
When did you leak urine most often? (Physical activity; bladder urge; without or about equally with physical activity or bladder urge.)

Based on the patient’s answers, the “3IQ” test may help a doctor distinguish between urge and stress urinary incontinence.

Voiding Diary. The patient might find it helpful to keep a diary for 3 to 4 days before the office visit. This diary, sometimes referred to as a voiding diary or log, should be a detailed record of:

Daily eating and drinking habits
The times and amounts of normal urination

For each incident of incontinence, the log should also detail:

The amount of urine lost (the patient is often asked to catch and measure urine in a measuring cup during a 24-hour period)
Whether the urge to urinate was present
Whether the patient was involved in physical activity at the time

The office visit should consist of a thorough physical examination, checking for abnormalities or enlargements in the rectal, genital, and abdominal areas that may cause or contribute to the problem.

One of the important measurements for urinary incontinence is the postvoid residual urine volume (PVR). This is the amount of urine left in the bladder after urination:

Normally, about 50 mL or less of urine is left
More than 100 mL suggests an abnormality and requires further tests
More than 200 mL is a definite sign of abnormalities

Use of a Catheter. The most common method for measuring PVR uses a catheter, which is inserted into the urethra after a few minutes of urination. The advantage of the catheter is that it can also collect urine for analysis.

Ultrasound. Ultrasound is useful in determining the volume of urine.

Cystometry measures the bladder's ability to retain urine at different capacities and pressures. It uses a catheter and can be performed at the same time as the PVR test.

Subtraction Cystometry. Although procedures vary, the basic steps for the technique are as follows:

The patient empties the bladder as much as possible.
Two catheters are inserted into the urethra until they reach the bladder. One is used to fill the bladder with water. The other is used to measure pressure. Another catheter is inserted into the rectum or vagina, which is used to measure abdominal pressure.
While water is instilled through the tube into the bladder, the pressure in the bladder and abdomen are measured and the results are recorded in a computing device.
During the process, the patient informs the doctor about any changes in the need to urinate, including the initial need to urinate, a normal desire to urinate, and a strong need to urinate.
Often during this process, the patient is asked to cough, bounce up and down, or even walk in place. The patient may also be asked to strain as if he or she is having a bowel movement. This is called the Valsalva maneuver. The point at which leakage occurs during this action is called the Valsalva leak point pressure, which might be a useful measurement for determining treatment.
When the urge to urinate is strong, the doctor stops this portion of the test.
A calculation is then made using bladder and abdominal pressure measurements as well as volume and flow rate of the urine. The result provides the doctor with an assessment of detrusor contractions.

The detrusor muscles of a normal bladder will not contract during bladder filling. Severe contractions at low amounts of administered fluid (less than 200 mL) indicate urge incontinence. Stress incontinence is suspected when there is no significant increase in bladder pressure or detrusor muscle contractions during filling, but the patient experiences leakage if abdominal pressure increases.

Video Cystometry. Video cystometry combines a computer reading of bladder pressures and pictures of the bladder itself. It is most useful in cases where the more standard tests have not yielded satisfactory results.

To determine whether the bladder is obstructed, the speed of urine flow is measured electronically using a test called uroflowmetry. The test involves the following steps:

Patients are instructed not to urinate for several hours before the test and to drink plenty of fluids so they have a full bladder and a strong urge to urinate.
To perform this test, a patient urinates into a special toilet equipped with a uroflowmeter.
It is important that patients remain still while urinating to help ensure accuracy, and that they urinate normally and do not exert strain to empty their bladder or attempt to retard their urine flow.

Many factors can affect urine flow (such as straining or holding back because of self-consciousness) so experts recommend that the test be repeated at least twice.

Q[max]. The rate of urine flow is calculated as milliliters of urine passed per second (mL/s). At its peak, the flow rate measurement is recorded and referred to as the Q[max]. The higher the Q[max], the better the patient's flow rate. Men with a Q[max] of less than 12 mL/s have four times the risk for urinary retention than men with a stronger urinary flow.

The Q[max] measurement is sometimes used as the basis for determining the severity of obstruction and for judging the success of treatments. It is not very accurate, however, for a number of reasons:

Urine flow varies widely among individuals as well as from test to test.
The patient's age must be considered. Flow rate normally decreases as men age, so the Q[max] typically ranges from more than 25 mL/s in young men to less than 10 mL/s in elderly men.

The Q[max] level does not necessarily coincide with a patient's perceptions of the severity of his own symptoms.

Urethrocystoscopy. Urethrocystoscopy, also called cystourethroscopy or cystoscopy, detects structural abnormalities, inflammation of the bladder wall, or masses that might not show up on x-ray.

The patient is given a light anesthetic, and the bladder is filled with water.
Next, a thin flexible tube called a cystoscope is inserted through the urethra into the bladder.
The end of the cystoscope contains a tiny microscope-like instrument.
The doctor uses the cystoscope to look for abnormalities in the interior of the bladder.

Cystoscopy is a procedure that uses a flexible fiber optic scope, which is inserted through the urethra into the urinary bladder. The doctor fills the bladder with water and inspects the interior of the bladder. The image seen through the cystoscope may also be viewed on a color monitor and recorded on videotape for later evaluation.

The procedure has some risks. Complications are uncommon, but can include allergic response to the anesthetic, urinary tract infection, bleeding, and urine retention.

Intravenous Pyelogram. Intravenous pyelogram (IVP) may be used to diagnose urge incontinence. It is performed as follows:

A dye is injected into the patient's vein and is processed by the kidneys.
A series of x-ray pictures are taken of the kidneys, ureter, and bladder as the dye passes through them. This provides a dynamic picture of the relationship between the patient's urinary system and urinary functioning.

IVPs can detect structural abnormalities, urethral narrowing, or incomplete emptying of the bladder. This test should not be used on pregnant women or patients with kidney failure. There is a risk for an allergic reaction to standard dyes, although newer, less allergenic ones are becoming available.

Ultrasound. Ultrasound plays a role in many cases of incontinence. For example, it is useful for men with prostate problems. It is helpful in measuring urine volume in the bladder. Ultrasound may also be useful in many cases of female stress incontinence, by identifying abnormalities in the bladder neck, and in assessing the urinary tract before and after surgery. It also may eventually be useful in diagnosing detrusor instability.

Chain Cystogram. In cases of stress incontinence, a chain cystogram may also be performed. With this procedure, a beaded chain is positioned in the bladder and urethra. The x-ray image of the chain reveals the angle of the bladder neck. This test should not be performed on pregnant women.

Electrophysiologic sphincter testing, also referred to as electromyography (EMG), evaluates two important factors:

The function of the nerves serving the sphincter and pelvic floor muscles.
The patient's ability to control these muscles.

Using a technique similar to that of an electrocardiogram, the doctor places electrodes on the affected areas to observe electrical activity in the muscles.

Urethral pressure profile is used to investigate urethral blockage. A probe is placed in the urethra to determine pressure at different points along this pathway during urination and the exact location of any obstruction in the urethra.

Prognosis

Incontinence is rarely life threatening. In most cases, if treated promptly, physical complications are not serious.

Urinary incontinence can have severe emotional effects. Depression is very common in women with incontinence. For example, in a 2003 study, 82% of women with severe incontinence and 41% of those with moderate incontinence reported at least 2 weeks of depression during the preceding year. Incontinence also has emotional effects on men. A number of studies of prostate cancer patients suggest that incontinence is a much more distressing side effect for men than impotence (also a side effect of prostate cancer treatment).

Other negative emotional effects reported include:

Loneliness and humiliation. Because little public attention has been paid to this problem, the incontinent person often feels alone and humiliated. Many people with incontinence do not even seek medical advice for the problem. In one survey of doctors, nearly all of them reported that a patient's embarrassment and reluctance to discuss bladder problems is a major barrier to successful treatment.
Shame. Many people experience a sense of personal failure.
Helplessness. Patients often feel helpless and angry.
Introversion. Patients may eventually curtail social activities, or even give them up entirely.
Lack of confidence. Many people with incontinence believe that they are unemployable.

To prevent humiliation due to wetness or odors, people with incontinence may have to alter their way of life.

Errands become very difficult and need advanced planning.
Public bathrooms may difficult to locate or unavailable. The problem is particularly severe for those with urge incontinence who have little time to reach a bathroom and have large volume spills.

Incontinence is particularly serious in older adults:

Older adults who are otherwise healthy may stop exercising because of leakage, which can increase their impairment.
Incontinence can result in loss of independence and quality of life.
It is a major reason for nursing home placement.
Severe incontinence may require catheterization. This is the insertion of a tube that allows urine to continually pass into an external collecting bag. In such cases, complications are common, particularly infections.
There is a strong association between urge incontinence and falls and injuries. In one large study, over half of women who reported incontinence experienced at least one fall over a 3-year period. This high incidence of falls may be due in part to the rush to the toilet in the middle of the night. Keeping a pan or portable commode near the bed may prevent injuries as well as improve sleep and general convenience.

Treatment

The treatment for temporary incontinence can be rapid, simple, and effective. If urinary tract infections are the cause, they can be treated with antibiotics. Any related incontinence will often clear up in a short time. Medications that cause incontinence can be discontinued or changed to halt episodes.

Chronic incontinence may require a variety of treatments, depending on the cause. Treatment options are listed below in the order in which they are usually tried, from least-to-most invasive:

Behavioral techniques, which include Kegel exercises and bladder training, are sometimes all a person needs for achieving continence. A number of devices can also be used to strengthen muscles and prevent urine leakage. Bladder training is useful for urge incontinence.
Medications are tried next. These may include anticholinergics and antispasmodics. Estrogen or estrogen plus progesterone used to be recommended, but recent research has shown that these hormone treatments can actually make urinary incontinence worse.
Surgery. Surgery is the last resort; there are many effective procedures available for stress incontinence.

Lifestyle techniques to improve quality of life and improve hygiene are part of all treatments.

Lifestyle measures, including dietary recommendations, bladder training, and continent aids, are useful for anyone with incontinence. Other treatments vary depending on whether the patient has stress or urge incontinence. In people who have both, the treatment usually is aimed at the predominant form.

Treating Stress Incontinence. The general goal for women with stress incontinence is to strengthen the pelvic muscles. Typical steps for treating women with type 1 stress incontinence are:

Devices and continent aids for blocking urine in the urethra (vaginal pessaries, adhesive pads, and others).
Behavioral techniques and noninvasive devices, including Kegel exercises, weighted vaginal cones, and biofeedback.
Medications. Alpha-adrenergic agonists and possibly tricyclic antidepressants.
Surgery is a reasonable option if symptoms do not improve with noninvasive methods. Many are available, and most are designed to restore the bladder neck and urethra to their anatomically correct positions.

Treating Urge Incontinence. The goal of most treatments for urge incontinence is to reduce the hyperactivity of the bladder. The following methods may be helpful:

Behavioral methods
Medications (anticholinergics, anti-spasmodics, and alpha blockers)
Procedures that stimulate the pelvic floor or nerves in the tailbone (the sacral nerves), which help retrain the bladder

Lifestyle Changes

Many products are now available that help patients avoid embarrassment and, in some cases, prevent leakage. With recent improvements in paper technology, pads are now thin enough to be worn undetected, and a spare can be hidden in a purse or pocket. Proper hygiene is also essential for patients with incontinence.

Keeping Skin Clean. To avoid skin irritation and infection associated with incontinence, keep the area around the urethra clean. The following tips may be helpful:

After a urinary accident, clean any affected areas right away.
When bathing, use warm water and don't scrub forcefully; hot water and scrubbing can injure the skin.
A number of cleansers are available that are specially created for incontinence and allow frequent cleansing without over-drying or causing irritation to the skin. Most do not have to be rinsed off; the area is simply wiped with a cloth.
After bathing, a moisturizer plus a barrier cream should be applied. Barrier creams include petroleum jelly, zinc oxide, cocoa butter, kaolin, lanolin, or paraffin. These products are water repellent and protect the skin from urine.
Anti-fungal creams that contain miconazole nitrate are used for yeast infections.

Preventing or Reducing Odor. Certain methods may help reduce odor from accidents. They include:

Deodorizing tablets, such as Derifil, Nullo, Devrom, and Chlorofresh can be taken by mouth or used in appliances. Most contain chlorophyll.
Taking an alfalfa pill four times a day may reduce odor, and is not believed to interfere with any other medications. Alfalfa is a common grass, and some people with seasonal allergies may experience an allergic reaction. Talk to your doctor before taking any type of supplement.
Drinking more water, not less, will also reduce odors. Drinking more water may actually help reduce leakage, too.
To remove odors from mattresses, some experts recommend a solution of equal parts vinegar to water. Once the mattress has dried, baking soda can be applied on the stain, rubbed in, and then vacuumed off.

Weight Control. In women, pelvic floor muscle tone weakens with significant weight gain, so women are urged to eat healthy foods in moderation and to exercise regularly.

Fluid Intake. A common misconception among people with incontinence is that drinking less water will prevent accidents. In reality, limiting fluid intake has the following effects:

The lining of the urethra and bladder becomes irritated, which may actually increase leakage.
Concentrated urine also has a stronger pungency, so drinking plenty of fluids can help reduce odor.

Some experts recommend drinking two to three quarts a day.

Drinking plenty of cranberry juice may be particularly helpful. It is known to help prevent urinary tract infections. (Low calorie juices are available.)

People with incontinence, however, should stop drinking beverages 2 - 4 hours before going to bed, particularly those who experience leakage or accidents during the night.

Fiber-Rich Foods. Constipation can worsen urinary incontinence, so diets should be high in fiber, fruits, and vegetables.

Fluid and Food Restrictions. A number of foods and beverages may increase incontinence. Some experts suggest that people who eat or drink the following items should try eliminating one a day over a 10-day period and check to see if removing them improves continence:

Caffeinated beverages. (In one major 2003 study, tea drinking -- but not coffee drinking -- was associated with incontinence. In general, however, it might be useful to try avoiding coffee as well, including decaf coffee.)
Carbonated beverages such as soda
Alcoholic beverages
Citrus fruits and juices
Tomatoes and tomato-based foods
Spicy foods
Chocolate
Sugars and honey
Artificial sweeteners
Milk and milk products

Some otherwise healthy adults stop exercising because of leakage. There are a number of methods for preventing or stopping leakage during exercise. The following are some tips:

Limit fluid intake before exercising (but be sure not to become dehydrated)
Urinate frequently, including right before exercise
Women can try wearing pads or urethral inserts

A variety of absorbent pads and undergarments are quite effective in catching spills and leaks. Many undergarments developed for incontinence are almost indistinguishable from regular briefs and underpants.

For women, the following are available:

Normal and even attractive looking washable underwear that contains waterproof panels is available for women. Even stomach-control panties are available for women with incontinence.

For men, the following are available:

Drip collectors are available which can be worn under briefs and are not noticeable under normal clothing. Lined with absorbent material, the pouch-like collector surrounds the penis or scrotum and is fastened with a belt or pins.
Washable briefs made from polyester have a fully functional fly and waterproof panel and look and feel like normal underwear. Boxer shorts are also available that look regular but have a protective pouch.

Even for men and women with severe incontinence, disposable undergarments can be purchased that have a normal look to them.

All absorbent undergarments should be changed when wet to limit problems of chafing or infection.

A specially shaped plastic urinal (Feminal) is available for women. It avoids the use of a bedpan, and can be used while the woman is lying down, seated, or even standing.

Urinals for men are available that attach to athletic-like supporters.

Other Treatments

Foam pads (Miniguard, UroMed, Impress, Softpatch) with an adhesive coating have been developed for women with stress incontinence. They work as follows:

The pad is placed over the opening of the urethra where it creates a seal, preventing leakage.
It is removed before urinating and replaced with a new one afterwards.
The pad can be worn up to 5 hours a day and through the night.
It can be used during physical activity, although it may change position during vigorous exercise.
It should not be worn during sexual intercourse.

In one study of women who used these products, the average number of leaks per week dropped from 14 to 5. Women with more severe incontinence (an average of 34 leaks a week) had only 10 events, and when leakage occurred, it was slight.

Adhesive pads should not be used by women with the following conditions:

Urinary tract or vaginal infections
Urge or other forms of nonstress incontinence
A history of surgery for incontinence

Urethral Shields. Shields or caps (CapSure, Bard Cap Sure, FemAssist) that fit over the urethral opening are safe and effective in managing many forms of incontinence.

In a study of patients with stress incontinence, CapSure reduced urine loss by 96% within a week, and 82% of patients were completely dry. Side effects include irritation and urinary tract infections, although they are not severe.
In another study, 47% of women who used FemAssist reported complete continence, and 33% of the women reported continence was improved by more than half. FemAssist offered equal benefits for women with stress, urge, or mixed incontinence.

Urethral Tubes or Sleeves. Tubes or sleeves (Reliance Urinary Control Device, FemSoft) that fit into the urethra are also available for female incontinence.

The Reliance Urinary Control Device for women is a small tube inserted into the urethra using a reusable syringe. The device must be prescribed by a doctor, who measures the woman's urethra to determine the right size. The tip of the tube contains a balloon that is inflated against the urethra and blocks urine, preventing leakage. Every time a woman urinates, she pulls a string that deflates the balloon, then throws the old device away and replaces it with a new one. It is effective, but carries a high risk for urinary tract infections and most women report discomfort and irritation.
FemSoft is a silicone tube insert surrounded by a liquid-filled sleeve. When the tube is inserted into the urethra, the sleeve conforms to its shape and creates a seal at the bladder neck, preventing leakage. It is intended for one-time use and is replaced after voiding. This is a relatively new product and information is lacking on its comfort and risk for urinary tract infections.

Vaginal Devices. Devices that support the vaginal wall also help support the urethra that is located next to it:

Tampons. Mild stress incontinence in women, particularly when induced by exercise, may be managed by using a tampon. Specially designed tampons (such as the Contrelle Continence Tampon) are available, but even simple menstrual tampons may be helpful. (Keep in mind that tampons can only be worn for a few hours.) As tampons push on the vaginal wall, it compresses the urethra. In one study, 86% of women with mild incontinence remained continent during exercise sessions when using tampons. Out of this group, however, only 29% with severe incontinence remained dry.
Vaginal Pessaries. Vaginal pessaries are devices inserted into the vagina that support the inside of the vaginal walls. Pessaries are usually made of silicon and come in various forms, including donut or cube-shapes. They must be fitted by a health professional and are effective for vaginal prolapse or other vaginal structural problems. Serious complications are rare but can occur if the pessary is not replaced periodically.
Introl Bladder Neck Support. The Introl bladder neck support prosthesis is a flexible ring that is inserted into the vagina and has two ridges that press against the walls, supporting the urethra. Sizing the Introl is difficult, but success rates of 83% have been reported in women with stress incontinence. It can be left in during urination but must be removed and cleaned afterward. Introl can cause vaginal or urethral infections and may also be uncomfortable.

Behavioral Treatments

With the exception of functional incontinence, most cases of incontinence will almost always improve with behavioral techniques. There are a variety of methods, but the focus is usually on strengthening or retraining the bladder. Studies indicate that such exercises are very effective, even for men recovering from surgery for prostate cancer.

To enhance bladder training for incontinent patients who are in nursing rooms, nurses may need to check patients for dryness and regularly remind them to urinate. As an extra tip for older people with severe incontinence, keeping a pan or portable commode near the bed may prevent injuries from falling as well as improve general convenience.

Perhaps the best first-line approach for any form of incontinence is a combination of Kegel exercises and bladder training. In one study, women who used this combination approach experienced an average 50% reduction in incontinence episodes, with nearly 40% of them achieving complete continence. It was equally effective for urge, stress, or mixed incontinence.

Studies also report that between 50 - 75% of patients who perform only Kegel exercises experience a substantial improvement in their symptoms, including elderly people who have had the problem for years. A 2006 review suggested that Kegel exercises are especially helpful for women in their 40s and 50s who suffer from stress incontinence. The women participated in a supervised Kegel exercise program for at least 3 months.

Pelvic Floor Muscle (Kegel) Exercises. Kegel exercises are designed to strengthen the muscles of the pelvic floor that support the bladder and close the sphincters.

Stress incontinence is an involuntary loss of control of urine that occurs at the same time abdominal pressure is increased as in coughing or sneezing. It develops when the muscles of the pelvic floor have become weak.

Dr. Kegel first developed these exercises to assist women before and after childbirth, but they are very useful in helping to improve continence for both men and women. Kegel exercises are particularly useful for the following conditions:

Stress incontinence. Some experts believe that Kegel exercises should be the primary treatment for stress incontinence.
Urge incontinence. They can also be helpful for urge incontinence in cases that are not caused by nerve damage. In one study, 85% of women reported satisfaction with this program.

The general approach for learning and practicing Kegel exercises is as follows:

Since the muscles are sometimes difficult to isolate, the best method is to first learn while urinating. The patient begins to urinate and then contracts the muscle in the pelvic area with intention of slowing or stopping the flow of urine. Women should contract the vaginal muscles as well. They can detect this by inserting a finger inside the vagina. When the vaginal walls tighten, the pelvic muscles are being correctly contracted.
An alternate approach is to isolate the muscles used in Kegel contractions by sensing then squeezing and lifting the muscles in the rectum that are used in passing gas. (Again, women should contract the vaginal muscles as well.)
Patients should place their hands on their abdomen, thighs, and buttocks to make sure there is no movement in these areas while exercising.
In order to achieve success, some experts recommend performing two exercises that have different timing for the hold and release of the contraction. Both should be done regularly.
The first method is used for strengthening the pelvic floor muscles. The patient slowly contracts and lifts the muscles and holds for 5 seconds, then releases them. There is a rest of 10 seconds between contractions.
The second method is simply a quick contraction and release. The object of this exercise is to learn to shut off the urine flow rapidly.
In general, patients should perform 5 - 15 contractions, three to five times daily.

Some notes of caution:

Once learned, Kegel exercises should not be performed while urinating more than about twice a month, since this practice may eventually weaken the muscles.
In women, incorrect or overly vigorous exercises may cause vaginal muscles to tighten excessively, resulting in pain during sexual intercourse.
Over-exercise can also tire muscles and cause more leakage.
Incontinence will return to its original severity if these exercises are discontinued, so commitment to the program must be high and possibly life-long.
It may be several months before the patient sees significant improvement.

Bladder Training. Bladder training involves a specific, graduated schedule for increasing the time between urinations:

Patients start by planning short intervals between urinations, then gradually progressing with a goal of voiding every 3 - 4 hours.
If the urge to urinate arises between scheduled voidings, patients should remain in place until the urge subsides. At the time, the patient moves slowly to a bathroom. (In a small study, 73% of women with stress incontinence were helped by an absurdly simple and obvious movement: crossing the legs whenever a cough or sneeze was coming on.)

This system uses a set of weights to improve pelvic floor muscle control. The cones are inexpensive, relatively simple to use, and evidence suggests that they are as effective as Kegel exercises or electrostimulation:

The typical set includes five cones of graduated weights ranging from 20 grams (less than 1 ounce) to 65 grams (slightly over 2 ounces).
Starting with the lightest, the woman places the cone in her vagina while standing and attempts to prevent the cone from falling out. The muscles used to hold the cone are the same ones needed to improve continence.

As with standard Kegel exercises, frequent repetition is required, but most women will eventually be able to use the heavier weights and build up the ability to prevent stress and urge incontinence.

Women who are unable to learn Kegel muscle contraction and release with verbal instructions can be helped with the use of biofeedback:

Biofeedback uses a vaginal or rectal probe inserted by the patient that relays information to monitoring equipment.
The patient isolates the pelvic floor and bladder muscles and performs Kegel exercises.
The monitor emits auditory or visual signals that indicate how strongly the patient is contracting the proper pelvic floor muscles and how effectively the bladder muscles are being released.
The apparatus is designed for home use.

As with any Kegel exercise regimen, biofeedback must be used for several months before it is effective. In one major study, 75% of women with urge incontinence reported satisfaction with biofeedback, although women who were simply given verbal cues were even more satisfied (85%). A 2005 study of older women found that biofeedback worked better than oxybutynin (Ditropan) in controlling nighttime urge incontinence. Biofeedback that teaches control of pelvic muscles may even be very helpful in children who have daytime wetting, frequent urinary tract infections, or both.

A treatment called extracorporeal magnetic innervation therapy stimulates pelvic muscles to automatically perform Kegel exercises:

The patients stay fully dressed and sit on a special chair during the treatment.
Highly focused magnetic fields penetrate the pelvic area to stimulate the nerves.
Sessions are twice a week for about 6 weeks, although it may take more than 8 weeks to build up the muscles.

Studies report that patients experience fewer leaks, need fewer pads, and have fewer voiding episodes throughout the day and night. Comparison studies of magnetic therapy and sham (or "dummy") treatments are mixed, however, with some reporting no differences. More studies are needed to determine whether extracorporeal magnetic innervation therapy has any value.

Electrical stimulation of the pelvic floor muscles has been a common treatment for years. The procedure uses a probe inserted into the anus or vagina, which produces a contraction in the pelvic floor muscles. Success rates range from 50 - 90% for urge incontinence. (It may also be useful for some patients with stress incontinence.) A recent study regarding patient-adjusted intermittent electrostimulation in women with stress or mixed urinary incontinence using a new implanted stimulator found the concept promising. Researchers, however, encouraged further investigation regarding the effectiveness and safety of the technique. The procedure requires frequent visits, and it takes 2 - 3 months before the patient feels the benefits. It is often not covered by insurance. Side effects can be distressing and include abdominal cramps, diarrhea, bleeding, and infection.

Medications

A number of medications are available that increase sphincter or pelvic muscle strength or relax the bladder, improving the ability to hold more urine. Medications are prescribed for all kinds of incontinence, but they are generally most helpful for urge incontinence.

Anticholinergics. Anticholinergics work in the following ways:

Inhibit the involuntary contractions of the bladder
Increase capacity of the bladder
Delay the initial urge to void

A major 2003 analysis reported that these drugs produce small but significant improvements. However, the medications have not been rigorously compared with behavioral methods, such as bladder training and Kegel exercises, which are very effective for most cases of urge incontinence. Anticholinergics can have distressing side effects, notably dry mouth.

Anticholinergics include:

Propantheline (ProBanthine). This drug used to be the most commonly prescribed anticholinergic, but has been largely replaced by newer anticholinergics with fewer side effects.
Oxybutynin (Ditropan, Oxytrol)
Tolterodine (Detrol)
Hyoscyamine (Levbid, Cystospaz)

Extended-release versions of oxybutynin (Ditropan XL) and tolterodine (Detrol LA) are proving to be especially effective. They improve continence and have fewer adverse effects than short-acting forms. In a major 2003 comparison study of the extended release drugs, oxybutynin was slightly better than tolterodine, but dry mouth was reported more often. A skin patch form of oxybutynin (Oxytrol) is now available. It appears to work better and have fewer side effects, such as dry mouth and constipation, than the pill form.

Oxybutynin may cause more severe central nervous side effects than previously thought, especially for children and older adults. In 2007, the FDA reviewed 202 cases of oxybutynin-related central nervous system problems. Hallucinations were reported in 27% of pediatric cases and 25% of cases involving adults age 60 and older. Eleven percent of adults age 17 – 59 years experienced hallucinations. The FDA recommends that doctors monitor patients for these symptoms.

According to one study of tolterodine, the drug also improved quality of life. A 2006 study reported that tolterodine is helpful for men with overactive bladder and urge urinary incontinence. A 2006 study, published in the Journal of the American Medical Association, suggested that a combination of tolterodine and the alpha-blocker drug tamsulosin (Flomax) may work better than either drug alone for men with lower urinary tract symptoms, including overactive bladder.

Overactive Bladder Treatments for Children

Oxybutynin (Ditropan X) is approved for pediatric use in children ages 6 and older. The recommended dose is 5 mg once a day. A 2006 study suggested that children who have fewer episodes of daytime wetting may benefit most from this drug.
A 2004 analysis found that tolterodine is also effective and well tolerated in children with urinary symptoms due to overactive bladder.

Side effects of anticholinergic drugs include:

Dry eyes (a particular problem for people who wear contact lenses; patients who wear contacts may wish to start with low doses of medication and gradually build up)
Dry mouth
Headache
Constipation
Rapid heart rate
Confusion, forgetfulness, and possible worsening of mental function, particularly in older people with dementia, such as those with Alzheimer's disease
Hallucinations, possibly, especially for children and older adults
Glaucoma, in rare cases

Antispasmodics. Antispasmodic drugs help relax the bladder muscle and are used for urge incontinence. Before bladder relaxants are prescribed, a thorough evaluation for obstructions in the ureter must be performed to avoid excessive urine retention.

Flavoxate (Urispas) and dicyclomine (Bentyl), the most common antispasmodics, have been used for years, although studies suggest that Urispas has very little benefit for the majority of patients with urge incontinence. The drugs also have anticholinergic properties. In May 2004, the FDA approved a new antispasmodic, trospium chloride (Sanctura), for the treatment of overactive bladder with symptoms or urge incontinence.

Possible side effects reported with use of antispasmodic drugs include:

Weakness
Dizziness
Drowsiness
Hallucinations
Insomnia
Dry mouth
Impotence
Restlessness

M3 selective receptor antagonists. In 2004, the FDA approved darifenacin (Enablex) for treatment of urge incontinence and overactive bladder. Some clinical trials suggested that darifenacin could help reduce weekly incontinence episodes by 83%. The drug’s most common side effects are dry mouth and constipation. For elderly patients, darifenacin may have less negative effects on memory than oxybutynin.

Capsaicin and Analogs. Studies have reported beneficial effects from instillation of capsaicin, a component of hot red chili peppers, into the bladder of people with hyperactive and hypersensitive bladders. Temporary adverse effects, however, can be distressing. A capsaicin analog called resiniferatoxin may be more effective than capsaicin and have fewer side effects.

Alpha-Blockers. Alpha-blockers are drugs that relax smooth muscles and improve urine flow. They are useful for men with benign prostatic hyperplasia who also have urge incontinence. They include terazosin (Hytrin), doxazosin (Cardura), tamsulosin (Flomax), and alfuzosin (Xatral). Tamsulosin may be particularly beneficial. A 2006 study published in the Journal of the American Medical Association reported that the combination of tamsulosin and tolterodine works better than either drug alone for men with moderate-to-severe lower urinary tract symptoms, including overactive bladder. Men in the study were age 40 years and older and had symptoms related to overactive bladder and benign prostatic hyperplasia.

Alpha-Adrenergic Agonists. Alpha-adrenergic agonists are used to strengthen the smooth muscle that opens and closes the internal sphincter. They include ephedrine and pseudoephedrine, which are common ingredients in numerous over-the-counter decongestants and appetite suppressants.

Such drugs may be helpful for patients with mild stress incontinence not caused by nerve damage, although evidence on their benefits is weak. They also can have significant side effects, particularly ephedrine. In fact, products containing a similar drug, phenylpropanolamine (PPA), have been taken off the market because of reports of a higher risk for stroke in some women who took it.

Side effects may include agitation, insomnia, and anxiety. They may have adverse effects on the heart in people with existing heart problems. People with glaucoma, diabetes, hyperthyroidism, heart disease, or high blood pressure should avoid alpha-adrenergic agonists.

Nitrovasolidators. Deficiencies in nitric oxide, a gas that keeps blood vessels open, have been associated with many disorders, including incontinence. Drugs that release nitric oxide, such as nitroflurbiprofen, are being investigated for urinary incontinence.

Evidence indicates that both urge and stress incontinence are affected, in part, by central nervous system processes, particularly signal transmission. Investigators are particularly interested in serotonin and noradrenaline, which are chemical messengers (called neurotransmitters) that affect pathways involved with urination. (These neurotransmitters are also important for many other emotional and physical functions.) Antidepressants targeting one or both of these neurotransmitters are sometimes used for urge incontinence and may also be helpful for some people with stress incontinence.

Tricyclic Antidepressants. Tricyclic antidepressants include imipramine (Janimine, Tofranil), doxepin (Sinequan), desipramine (Norpramin), and nortriptyline (Pamelor). They provide multiple benefits for both urge and stress incontinence. They act as anticholinergic drugs and relax the bladder. They also strengthen the internal sphincter. These drugs should be used carefully. They pose some risk for adverse effects on the heart and possibly the lungs, and they have other severe side effects in older adults. These antidepressants produce side effects similar to anticholinergic drugs, and may cause drowsiness. They may also backfire and actually cause overflow incontinence in some people.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs). SNRIs are specially designed antidepressants that are similar to tricyclics but do not have the same side effects. The neurotransmitters serotonin and norepinephrine are thought to play key roles in the normal action of bladder muscles and nerves. Increased neurotransmitter activity stimulates the nerve that controls the urethral sphincter. The SNRI duloxetine (Cymbalta) is approved in Europe for treatment of stress urinary incontinence. (It is approved in the U.S. for other conditions, but not stress urinary incontinence.) In 2005, the manufacturer of duloxetine withdrew its drug application after a small number of women in duloxetine urinary incontinence trials tried to commit suicide. The FDA is investigating whether duloxetine can cause suicidal behavior.

Desmopressin. Studies have reported that desmopressin (DDAVP), a drug used for bedwetting in children, may be helpful in treating adults with urinary incontinence that occurs during sleep. The drug affects sodium levels, and there is a slight risk for water intoxication with this drug.

Botulinum (Botox). Botulinum, the deadly toxin that sometimes contaminates improperly cooked foods, is also a powerful muscle-relaxant. Tiny injected amounts of a purified form (Botox) can relax the muscles and may help control overactive bladder that causes urge incontinence. It may also help relieve urinary retention that might occur after incontinence surgeries.

Stem Cells. Researchers are investigating muscle stem cell injections as a treatment for stress incontinence. Several small studies have indicated promising results. In these experiments, a doctor took a biopsy of skeletal muscle tissue from a patient’s arm. Stem cells were cultured and isolated from the biopsy sample. The doctor then injected the muscle-derived stem cells into the area surrounding the patient’s urethra that is close to the damaged sphincter muscle. In research results presented at the 2007 American Urological Association annual meeting and the 2006 Radiological Association of North American Meeting, patients experienced sustained improvements in bladder control and quality of life.

Surgery

There are nearly 200 procedures for incontinence. Most are designed to restore the bladder neck and urethra to their anatomically correct positions in patients with stress incontinence.

The American Urological Association suggests that surgery should actually be considered as initial therapy for women with severe stress incontinence. It is an effective and safe alternative when conservative treatments fail. Many of the procedures are safe even for women up to 80 years old who do not have serious medical conditions. Potential complications of all procedures include obstruction of the outlet from the bladder, causing difficulty in urination and irritation.

Deciding which procedure to choose is difficult and often depends on the factors causing the incontinence and whether anatomical abnormalities are involved. It should be noted that although hysterectomy has been shown to improve incontinence, it must not be performed only as a cure for incontinence.

In general, patients should weigh all options carefully. They should discuss the situation with their doctor, and ask about their surgeon's experience. As a general rule, the more times a surgeon has successfully performed a procedure, the better.

Retropubic Colposuspension Surgery. Retropubic colposuspension using standard "open" surgery is an effective treatment for stress incontinence, especially over the long term. ("Open" surgery implies the use of a wide incision in order to "open" the area.) Long-term continence rates can range from 85 - 90%.

The goal of colposuspension is to correct the position of the bladder and urethra by sewing the bladder neck and urethra directly to the surrounding pelvic bone or nearby structures. There are many variants, but, in general, they are effective only for women with urethral hypermobility. Most procedures require a general or spinal anesthetic and a 2-day hospital stay.

Burch colposuspension (sometimes called colpocystourethropexy) is a standard approach. It requires a wide abdominal incision and is often performed during abdominal surgeries such as hysterectomy or hernia operations. It is also performed along with sacrocolpopexy, a surgical procedure used to repair pelvic organ prolapse. (Pelvic organ prolapse occurs when the uterus or bladder slips from the pelvic cavity into the vagina. It is often due to pelvic muscle weakness that develops after childbirth.) Prolapse can lead to stress incontinence. However, prolapse surgery itself sometimes causes incontinence. A 2006 study suggested that a Burch colposuspension performed at the same time as sacrolpopexy can help reduce postsurgical stress incontinence.

The surgeon secures the urethra and bladder neck with lateral (sideways) sutures that pass through thick bands of muscle tissue running along the pubic bones. Unlike an older suspension procedure, this procedure poses a much lower risk for obstruction of the urethra. It is more effective in premenopausal than postmenopausal women and may not be appropriate for all women.

A rigorous 2007 study published in the New England Journal of Medicine compared the effectiveness of the Burch colposuspension to the sling procedure, another type of surgical treatment for stress incontinence. The study found that the sling procedure had better results for achieving dryness. However, more women who had the sling procedure had post-operative urinary problems, especially urinary tract infections. Overall, women were satisfied with the outcomes of both procedures. Eighty-six percent of women who had a sling procedure and 78% of women who had a Burch colposuspension reported satisfaction with their treatment.

Marshall-Marchetti-Krantz (MMK). The MMK approach requires a wide abdominal incision. The surgeon then elevates the urethra and bladder neck using sutures. These structures are then secured and anchored in nearby cartilage. This approach is one of the most reliable, but is used less often because of the risk for scarring and because the incision limits the surgeon's ability to correct any potential hernias (cystoceles).

Laparoscopy. Other less invasive procedures use laparoscopy, which requires only one or two small incisions over the pubic bone. Evidence suggests that laparoscopy, performed by an experienced surgeon, works just as well as standard surgery. While laparoscopy has a higher complication rate, it also has a faster recovery time and less postoperative pain. Still, well-conducted long-term studies are needed for an accurate comparison with standard colposuspension.

Needle Suspension. Needle suspensions include a number of approaches, including the Pereyra, Stamey, Raz, and Gittes procedures. The basic approach places stitches on either side of the bladder and ties them to muscle tissue or the pubic bone. Some of these procedures use transvaginal suspension, which requires only a small abdominal incision or no incision at all. In this case, the surgeon works through the vagina and places sutures through the vaginal walls. Transvaginal suspension works only if the walls of the vagina are strong enough to withstand the procedure. Some studies report poor long-term results, particularly compared to colposuspension. In one study, only 35% of patients who had transvaginal suspension reported success after 6 years. In another study, the failure rate was 83% after 4 - 5 years. Additional research has indicated that 20% of women have worse sexual function after the procedure.

Postoperative Considerations for Most Procedures. Following most standard procedures, patients usually leave the hospital on the second or third day, but need a urinary catheter for about 10 days. Newer procedures may require shorter stays and less intensive postoperative care.

Complications after surgery include:

Some risk of damage to the surrounding nerves or vessel. This can result in internal sphincter deficiency. (In some cases it may already have been present before the operation.)
Difficulty in urinating from surgical overcorrection. (This may require additional surgery.)
Poor wound healing.
Adhesions (scar tissue) that obstruct the urethra. This complication is higher with older standard procedures.
Vaginal abnormalities (prolapsed vagina).

A sling procedure may be a good option for severe stress incontinence in women who have either intrinsic sphincter deficiency or urethral hypermobility. The method is even proving to help women with mild-to-moderate incontinence and young girls with severe incontinence. It may also be useful for managing female urge incontinence. Sling procedures are also available for men who experience incontinence after prostatectomy.

Until recently, there were few clinical trials that directly compared the sling procedure with Burch colposuspension. In 2007, the New England Journal of Medicine published the results of the largest and most rigorous clinical trial conducted on these two types of surgery. In this study of 655 women with stress incontinence, half of the women underwent the sling procedure and half had open surgery with the Burch colposuspension.

Two years after surgery, success rates were highest for women who had the sling procedure. Forty-seven percent of women who had the sling procedure reported no urinary incontinence (either stress or urge) compared to 38% of women who had the Burch procedure. For stress-only incontinence, 66% of women who had the sling procedure and 49% of women who had the Burch procedure were dry. Eighty-six percent of women who had the sling procedure and 78% of the Burch group reported satisfaction with their treatment.

However, women who had the sling procedure did experience more post-operative urinary problems. The most common complication was urinary tract infections, which affected 63% of women who had a sling procedure compared with 47% of women who had the Burch procedure. A small number of women who had a sling procedure also reported difficulty voiding and urge incontinence.

The Percutaneous Sling Procedure for Women. The procedure generally works as follows:

The surgeon makes an incision above the pubic bone and removes a layer of abdominal fasci (tissue that covers muscle fibers). This muscle strip is set aside and later serves as the sling. (The uses of fasci taken from a cadaver or synthetic slings are also being investigated. However, the natural muscle strip may last longer than some of the common synthetic materials.)
The surgeon makes an incision in the vaginal wall. The piece of muscle fiber or material is attached under the urethra and bladder neck, somewhat like a hammock, and secured to the abdominal wall and pelvic bone.
This sling then compresses the urethra back to its original position. The sling must be supportive without being too tense, which can cause urinary obstruction.

Complications can include infection, bleeding, and the formation of fistulas (holes that form and are usually infected).

Vaginal Sling and Tape Procedures for Women. Newer outpatient procedures do not use abdominal incisions. Instead, they are performed through a small incision in the vagina. Typically, two small tacks are placed in the pubic bone. A sling is inserted into the vagina and is attached to the tack.

The tension-free vaginal tape (TVT) procedure uses a special gauze tape covered by a polypropylene coating, which is attached on each side of the urethra. The patient remains conscious and is asked to cough during the procedure so that the surgeon can determine if the tape is secure. Small early studies showed that the procedure worked as well as colposuspension (the standard suspension procedure), with stress incontinence cure rates of 84 - 100%. According to a 2005 study, the benefits of TVT can last for up to 8 years for women with stress incontinence. However, women with mixed incontinence (a combination of stress and urge) did not fare as well. Women with mixed incontinence had a 60% cure rate during the first 4 years following surgery, but the cure rate declined to 30% within 4 - 8 years post-surgery.

Sling Procedures in Men. For some men who have prostatectomy-induced incontinence, sling procedures may be a good option. Researchers have reported an 80% success rate, the same as an artificial urinary sphincter, which is the standard surgical treatment for such patients. The sling procedure has been less effective in men who have had radiation therapy, although improved techniques are making this approach useful even for these patients. Minimally invasive procedures are also being tested.

Artificial Sphincter. In cases of sphincter incompetence, or complete lack of sphincter function, an artificial internal sphincter may be implanted. This procedure is useful for appropriate male and female candidates of any age, including children. It is particularly helpful for men after radical prostatectomy. Studies have found poor results for patients with incontinence due to radiation therapies, although a 2001 study of men with prostatectomy indicated that it was useful regardless of previous radiation therapy.

Click the icon to see an illustrated series detailing artificial sphincter surgery.

This device uses a balloon reservoir and a cuff around the urethra that is controlled with a pump. The patient opens the cuff manually by activating the pump. The urethra opens and the bladder empties. The cuff closes automatically several minutes later. The two major drawbacks of the internal sphincter implant are:

Malfunction. If the implant malfunctions, the surgery must be performed again.
Infection. Infection is more serious as it can cause erosion of the urethra or bladder neck underneath the implant. Such infections not only require removal of the device, but also may worsen the incontinence. Fortunately, techniques have improved so that infection is uncommon.

In a 2001 study, after an average of 7 years, 70% of female patients with stress incontinence had either the original implant or a replacement, and 82% had urination properly restored. (Only 37% still had the original implant, however.) Studies on men have reported similar findings, although newer devices that use narrow cuffs may significantly improve re-implantation rates. Nearly all patients still need to use pads for leakage.

Injections of materials, such as collagen, that provide bulk to help support the urethra are proving to be beneficial for the following patients:

Women (even the elderly) with severe stress incontinence who cannot or do not wish to have surgery that involves anesthesia.
Men who have slight incontinence caused by prostate surgery. Men who have bulking injections after TURP (transurethral resection of the prostate) have a continence rate that is equal to the rate in women. After radical prostatectomy (removal of the prostate gland in prostate cancer), collagen injections can achieve some level of continence in up to nearly half of men. (Collagen injections are not beneficial after radiation therapy for prostate cancer.)

The Procedure.

First, bladder instability or hyperactivity should be medically treated and managed to control muscle activity before having the procedure. Otherwise it is likely to fail.
The basic procedure involves injecting bulking material into the tissue surrounding the urethra.
The material used is usually animal or human collagen. (Collagen is the basic protein in bones, muscles, and all connective tissue.) Synthetic bulking materials, such as carbon-coated beads, are also being used.
The doctor passes the collagen-containing needle through a cystoscope, a tube that has been inserted into the urethra. The collagen can also be injected into the skin next to the sphincter.
The injected collagen tightens the seal of the sphincter by adding bulk to the surrounding tissue.
The procedure takes about 20 - 40 minutes, and most people can go home immediately afterward.
Two or three additional injections may be needed to achieve satisfactory results.

Postoperative Care. People may experience immediate improvement followed by a temporary relapse after a week or so. Patients must be taught to use a catheter tube for withdrawing urine for a few days following the procedure. In general, it takes about a month for the full benefits to be apparent.

Complications.

There is a risk for infection and urinary retention, although these conditions are temporary.
An increase in autoimmune disease has been reported in a small number of cases.
The procedure may not be appropriate for patients with certain cardiac conditions.

Duration of Effectiveness. Collagen is absorbed over time, so injections generally need to be repeated every 6 - 18 months. According to one study, however, after a year 44% of women who had the implants still experienced the same level of improvement. (Synthetic materials may last longer than collagen from other sources, but they pose a risk for rejection as well as migration to the lymph nodes and other parts of the body.)

Anterior vaginal repair procedures that correct a prolapsed (fallen) uterus or vagina can often correct incontinence in women who have these conditions. The anterior vaginal repair (also called a bladder tuck) requires an incision to be made through the vagina. This releases part of the anterior (front) vaginal wall, which is attached to the base of the bladder. The pubocervical fascia (the supportive tissue between the vagina and bladder) is folded and stitched to bring the bladder and urethra into proper position. Several variations on this procedure may be necessary, depending on the severity of the prolapse. It is not as effective as retropubic suspension procedures, however, and should not be used as the primary method for correcting incontinence.

An interesting investigative approach uses radiofrequency energy to shrink tissue that supports the bladder neck and reduces hypermobility. Early studies are promising. In one, for example, the cure rate was nearly 80% at the end of a year, and 83% of patients reported satisfaction with the procedure.

Other Procedures

The sacral nerves, located in the tail bone, appear to play an important role in regulating bladder control. A sacral nerve stimulation system (InterStim) is now available for patients with urge incontinence. The system sends electrical pulses to the sacral nerves to help retrain them. InterStim is reserved for the treatment of urinary retention and the symptoms of overactive bladder in patients who have failed or cannot tolerate less invasive treatments. The system works as follows:

A stopwatch-size device is implanted under the skin in the abdomen.
A wire connected to it runs to the sacral nerves in the lower back.
The device, a battery-operated generator, produces electrical pulses.
The pulses are sent to the sacral nerves and reduce the hyperactivity of the bladder.
The sensation of the electrical pulse is similar to a slight pulling sensation in the pelvic area. Sometimes it can cause a small jolt or shock if the patient changes posture quickly. It should not cause pain. (If it does, something is wrong with the device.)

Complications include infection, lower back pain, and pain at the implant site. The system, however, does not cause nerve damage and can be removed at any time.

Patients have reported improvement in the frequency and volume of urination, as well as the intensity of urgency and their quality of life. Studies report complete dryness in nearly half of patients, with about 75% of patients experiencing relief from heavy leaking.

Transcutaneous Neuromodulation. The use of electrodes on the surface of the skin, called transcutaneous neuromodulation, may prove to be beneficial and particularly attractive for children.

Percutaneous Stoller Afferent Nerve Stimulation. The percutaneous stoller afferent nerve system (PerQ SANS System) has also been approved for urge incontinence.

In this therapy, a very thin needle is inserted a short distance above the ankle bone.
The needle is applied to the tibial nerve in the ankle, which connects with the sacral nerve complex.
Low-frequency electrical stimulation is applied for 30 minutes once a week for about 3 months.
After that, depending on the patient's response, treatments are given every week to every other week.
Short-term results are promising, but more research is needed.

Catheters and Collection Devices

A catheter is a slim flexible tube inserted into the urethra. They are mainly used for cases of severe urge incontinence.

A catheter (a hollow tube) may be inserted into the urinary bladder when there is a urinary obstruction, following surgical procedures to the urethra, in unconscious patients (due to surgical anesthesia, coma, etc.), or for any other problem in which the bladder needs to be kept empty (decompressed) and urinary flow assured.

Temporary Catheterization. For people who are still active, catheterization is often very distressing. If possible, temporary, also called intermittent, catheterization is usually the best choice. Patients insert the catheter tube into their urethras, generally every 3 - 4 hours. This type of catheterization carries few risks and empties the bladder completely. Some patients report that they can maintain an active life with no significantly increased risk for infection with some simple precautions:

Sterilize catheters at home.
Use a Zip Lock plastic bag for carrying them when leaving home.
Use another plastic bag for antiseptic cleansing solution.
When using public bathrooms, wash before and after catheterization. Touch as few places in the bathroom as possible.

Permanent Catheterization. People who are mentally or physically incapable of self-catheterization may need permanent catheterization.

The permanent catheter is inserted by a doctor or nurse into the opening of the bladder and a cuff is inflated to hold the tube in place.
Urine drains to an external collection device, which is generally strapped to the leg and must be emptied periodically.

The procedure is not painful, but there is a substantial increased risk of infection. Many experts feel that the catheter is overused, especially in the elderly.

Condom Catheters. Condom catheters are much more satisfactory than standard catheters for many male patients, although there is more spillage.

The condom is worn all day.
At night it is removed and washed for reuse the next day.

Collection Devices Attached to the Leg. For chronic or severe incontinence, collective devices drain urine into a bag that is attached to the lower leg and emptied periodically. These are generally more successful for men. Urine can be funneled into the tube by a pouch surrounding the penis. The positioning of the collecting device is difficult for women, and more accidents occur. For both men and women, irritation of the area around the urethral opening is a problem, since urine is in contact with the area for long periods.

Highlights

Drug Approval

Women with menstrual pain due to endometriosis have a new treatment option. In May 2007, the FDA approved Lybrel, a continuous-dose oral contraceptive that completely eliminates menstrual periods. Lybrel, which contains low doses of the estrogen estradiol and the progesterone levonorgestrol, is taken 365 days a year with active pills. Some women may, however, experience unscheduled bleeding or spotting.

Endometriosis and Adenomyosis

Women who continue to experience menstrual and pelvic pain after surgery for endometriosis may actually have adenomyosis, suggests a 2006 study in Fertility and Sterility. Adenomyosis occurs when knots of endometrial tissue develop within the muscles of the uterus. With endometriosis, endometrial tissue grows outside of the uterus.

Predictors of Hysterectomy

Three factors combined can predict whether a woman will decide to have a hysterectomy, according to a 2007 study published in the Journal of the American College of Surgeons. Women who met all three criteria had a 95% chance of having a hysterectomy:

Presence of symptoms (pelvic pain, bleeding, symptomatic fibroids)
Lack of symptom improvement despite treatment
Previous use of GnRH agonist drugs

Hysterectomy and Sexual Function

Women who have both their uterus and cervix removed (total hysterectomy) are no more likely to experience sexual problems than women who have only their uterus removed (subtotal hysterectomy), suggests a 2006 review in the Cochrane Database. The review also found no differences between total and subtotal hysterectomy for urinary and bowel problems. However, women who had subtotal hysterectomy were more likely to experience cyclical bleeding during the year after surgery than women who had a total hysterectomy.

Hormone Replacement Therapy (HRT) and Breast Cancer Risk

Estrogen-only HRT after hysterectomy does not increase breast cancer risk in the short term (up to 20 years), according to several 2006 studies. Combination estrogen-progestin HRT does increase breast cancer risk.

Introduction

Endometriosis is a condition in which the cells that line the uterus grow outside of the uterus. The condition can interfere with a woman's fertility and ability to become pregnant. Endometriosis can also cause severe pelvic pain, especially during menstruation.

Endometriosis is a common gynecological condition. It was described in medical literature more than 300 years ago and has since been recognized as a chronic, painful, and often progressive disease in women. However, the causes of endometriosis are unknown, it is widely variable in symptoms and severity, and it is difficult to diagnose. In fact, some experts believe that endometriosis is actually several disorders, not just one.

Endometriosis. Endometriosis occurs when cells from the mucus membrane lining the uterus (endometrium) form implants that attach, grow, and function outside the uterus, generally in the pelvic region. Endometrial implants consist of both following cell types:

Gland cells. These cells secrete hormones and other fluids and are normally located in the uterine lining.
Stroma cells. These are the framework cells that build supportive tissue.

Endometrial cells contain receptors that bind to estrogen and progesterone, which promote uterine growth and thickening. During endometriosis these cells become implanted in organs and structures outside the uterus, where these hormonal activities continue to occur, causing bleeding and scarring.

Endometriosis is the condition in which the tissue that normally lines the uterus (endometrium) grows on other areas of the body, causing pain and irregular bleeding.

Endometrial implants vary widely in size, shape, and color. Over the years, they may diminish in size or disappear, or they may grow.

Early implants are usually very small and look like clear pimples.
If they continue to grow they may form flat injured areas (lesions), small nodules, or cysts called endometriomas, which can range from sizes smaller than a pea to larger than a grapefruit.
Implants also vary in color; they may be colorless, red, or very dark brown. These so-called chocolate cysts are endometriomas filled with thick, old, dark brown blood that usually appear on the ovaries.

Implants can form in many areas, most commonly in the following:

The peritoneum. This is the smooth surface lining that covers the entire wall of the abdomen and folds over inner organs in the pelvic area.
On or next to the ovaries.

Less commonly they occur in other areas:

Cul-de-sac, an area between the uterus and rectum
Connective tissue that supports the uterus (called the uterosacral ligaments)
Vagina
Fallopian tube
Urinary tract (in about 20% of cases, usually without causing symptoms).
Gastrointestinal tract (in 12 - 37% of patients)

Click the icon to see an image of the female reproductive anatomy.

Very rarely, they appear in areas far from the pelvis, including the lungs and even the arms and thighs.

The process of endometriosis mimics menstruation at certain stages:

Each month, the exiled endometrial implants respond to the monthly cycle just as they would in the uterus. They fill with blood, thicken, break down and bleed.
Products of the endometrial process cannot be shed through the vagina as menstrual blood and debris are. Instead, the implants develop into collections of blood that form cysts, spots, or patches.
Lesions may grow or reseed as the cycle continues.

The lesions are not cancerous, but they can develop to the point that they cause obstruction or adhesions (web-like scar tissue) that attach to nearby organs, causing pain, inflammation, and sometimes infertility.

The primary structures in the reproductive system are as follows:

The uterus is a pear-shaped organ located between the bladder and lower intestine. It consists of two parts, the body and the cervix.
When a woman is not pregnant the body of the uterus is about the size of a fist, with its walls collapsed and flattened against each other. During pregnancy the walls of the uterus are pushed apart as the fetus grows.
The cervix is the lower portion of the uterus. It has a canal opening into the vagina with an opening called the os, which allows menstrual blood to flow out of the uterus into the vagina.
Leading off each side of the body of the uterus are two tubes known as the fallopian tubes. Near the end of each tube is an ovary.
Ovaries are egg-producing organs that hold 200,000 - 400,000 follicles (from folliculus, meaning "sack" in Latin). These cellular sacks contain the materials needed to produce ripened eggs, or ova.

The inner lining of the uterus is called the endometrium, and during pregnancy it thickens and becomes enriched with blood vessels to house and support the growing fetus. If pregnancy does not occur, the endometrium is shed as part of the menstrual flow. Menstrual flow also consists of blood and mucus from the cervix and vagina.

Reproductive Hormones. The hypothalamus (an area in the brain) and the pituitary gland regulate the reproductive hormones. The pituitary gland is often referred to as the master gland because of its important role in many vital functions, many of which require hormones. In women, six key hormones serve as chemical messengers that regulate the reproductive system:

The hypothalamus first releases the gonadotropin-releasing hormone (GnRH).
This chemical, in turn, stimulates the pituitary gland to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
Estrogen, progesterone, and the male hormone testosterone are secreted by the ovaries at the command of FSH and LH and complete the hormonal group necessary for reproductive health.

Causes

Endometriosis occurs among women all over the world, but researchers have been unable to determine its cause. A combination of genetic, biologic, and environmental factors appear to work together to trigger the initial process, to produce implantation, and to trigger subsequent reseeding and spreading of the implants.

Retrograde Menstruation. One explanation for the development of endometriosis implants involves retrograde menstruation. This occurs during a woman's period, when menstrual tissue flows backward through the fallopian tubes rather than out through the vagina. Early theorists suggested that, in some cases, the redistributed uterine tissue attached and grew in areas outside the uterus, forming endometriosis implants. This theory does not fully explain endometriosis, however. Many women experience some retrograde menstruation, but not all of them develop endometrial cysts. Consequently, other factors must explain why uterine tissue becomes implanted and grows in areas outside the uterus.

Lymphatic Transport. This theory suggests that endometriosis first develops when uterine tissue is separated and then is transported to other organs by way of the lymphatic system or the bloodstream.

The lymphatic system filters fluid from around cells. It is an important part of the immune system. When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes. Common areas where lymph nodes can be easily felt, especially if they are enlarged, are: the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).

Environmental Toxins. Other suspects for causing initial development of endometriosis are chemicals called organochlorines, which include dioxins (such as PCBs and furans). These chemicals have estrogen-like effects and are widely found in pesticides and other common products. The organochlorines have a particularly powerful impact on the ovary. Organochlorines have been associated with infertility, certain reproductive cancers, and autoimmune disorders, conditions that also occur with higher frequency in women with endometriosis.

Candida. There is absolutely no evidence that endometriosis is caused by candida (commonly called yeast infection), as claimed in some consumer publications.

There are two basic mysteries surrounding the persistence and growth of endometriosis:

Why do endometrial implants survive the attack by the immune system, which is typically launched against any foreign presence in the body?
How do these endometrial travelers develop new blood vessels and implant themselves in other locations?

Impaired Immune System.Some research is focused on possible immune disorders in women with endometriosis. One theory proposes that women with endometriosis have fewer natural killer (NK) cells, which are factors in the immune system important for surveillance. In their absence, the immune system is weakened and may allow endometrial tissue to invade and take root. A recent study suggests that other types of immune system cells are also underactive in women with endometriosis, allowing the woman's body to tolerate the implanted tissue.

Some evidence suggests that endometriosis represents an autoimmune condition, in which the immune system launches an attack on its own cells and tissue. Much of the evidence rests on the relatively high incidence of other inflammatory autoimmune disorders (multiple sclerosis, rheumatoid arthritis, lupus) that occur in women with endometriosis. It is unclear, however, how this response relates to endometriosis itself and whether endometriosis should be treated as an autoimmune condition.

Growth Factors and Angiogenesis. Macrophages also produce growth factors, which are of particular interest because they play important roles in angiogenesis, a natural process by which new blood vessels form.

Vascular endothelial growth factor (VEGF) is secreted by endometrial cells, and so is of special interest. Under normal conditions, VEGF is secreted within the uterus. When oxygen levels drop following menstruation and blood loss, VEGF levels rise and promote the growth of new blood vessels. This process is important for repairing the uterus following menstruation.

When endometrial cells land outside the uterus, however, investigators theorize that this same process occurs with unfortunate results. The cells secrete VEGF when they are deprived of blood and oxygen, which in turn stimulates blood vessel growth. In this case, however, blood vessel growth serves to promote implantation outside the womb.

Other growth factors involved in angiogenesis that may play a role in endometriosis include transforming growth factors (such as TGF-beta), platelet-derived endothelial growth factor (PD-ECGF), and tumor necrosis growth factors.

Inflammatory Response. The damage, infertility, and pain produced by endometriosis may be due to an overactive response by the immune system to the early presence of endometrial implants. The body, perceiving the implants as hostile, launches an attack. Levels of large white blood cells called macrophages are elevated in endometriosis. Macrophages produce very potent factors, which include cytokines (particularly those known as interleukins) and prostaglandins. Such factors are known to produce inflammation and damage in tissues and cells.

A major study is underway to uncover the genetic factors that predispose certain women to endometriosis. The incidence of endometriosis in women who have a mother or sister with the disorder may be up to 10 times higher than average.

Symptoms

Pain at the time of menstruation (dysmenorrhea ) is the primary symptom and occurs in nearly all girls and women with endometriosis. Studies suggest that endometriosis is the cause of about 15% of cases of pain in the pelvic region in women.

Timing of Pain. In addition to menstruation, endometrial pain can occur at other times of the month. A survey published by the Endometriosis Association reported the following findings on the timing of endometrial pain:

71% of women reported pain within 2 days after their periods started.
47% reported pain in the middle of a cycle. (A sharp pain during ovulation may be due to an endometrial cyst located in the fallopian tube that ruptures as the egg passes through.)
40% reported pain at other times of the month.
20% reported continual pain.
7% said there was no pattern.
Many women with endometriosis experience pain during intercourse.
Adolescents are more likely to experience pain that occurs both during their periods and at other times in the cycle, while in older women endometrial pain is more likely to occur during menstruation.

Location of Pain. Nearly all women with endometrial pain experience it in the pelvic area (the lower part of the trunk of the body). The pain is often a severe cramping that occurs on both sides of the pelvis, radiating to the lower back and rectal area and even down the legs.

Occasionally, however, pain may also occur in other regions if endometriosis affects other part of the pelvic area, such as the bladder or intestine.

Severity of Pain. The severity of the pain also varies widely and does not appear to be related to the extent of the endometriosis itself. In other words, a woman can have very small or few implants and have severe pain, while those with extensive endometriosis may have very few signs of the disorder except for infertility. Large cysts can rupture and cause very severe pain at any time.

Patients may experience additional symptoms, which include the following:

Joint and muscle aches
Fatigue
Bloating
Nausea
Dizziness
Heavy menstrual bleeding
Headaches
Depression and malaise (feeling generally low)
Sleep problems

Risk Factors

Endometriosis affects at least 5.5 million women in North America and millions more worldwide. An estimated 2 - 4% of all premenopausal adult women have detectable endometriosis, and over a third of these women experience noticeable pain. Because many women with endometriosis have no symptoms, the actual percentage of premenopausal women with the disorder may be as high as 15%. Some experts believe endometriosis may be responsible for between 45 - 70% of chronic menstrual pain in adolescence.

Age. Endometriosis can occur in women of all ages. It has been reported in girls as young as age 8 (and has been documented before the onset of menstruation), and in women over age 75, with the average age being between 25 - 29. About 40 - 60% of women with endometriosis report symptoms before age 25.

Ethnic Groups. Endometriosis is most common among Asian women, with Caucasians next. It is reported least frequently in African-American women.

Women at higher risk for endometriosis tend to have more problems with menstruation. Those at higher risk have a shorter than normal cycle, heavier periods, and longer periods. Heavier, more frequent periods, or longer exposure may simply make the risk for retrograde menstruation more likely. (This is the condition in which menstrual flows backward and is believed to be at least partially responsible for the initial development of endometriosis.) Menopause usually brings an end to mild-to-moderate endometriosis, although if women with a history of endometriosis take hormone replacement therapy (HRT), the condition may be reactivated.

Not having children has been associated with a greater risk for endometriosis. Some evidence suggests that early pregnancy may be protective against endometriosis because the cervix becomes dilated during labor, which reduces the risk for retrograde menstruation (menstrual backflow). On the other hand, endometriosis itself can increase the risk for infertility, so it may be a cause rather than a result of not having children. Some studies have found no protection against endometriosis with pregnancy, although women with the condition find relief from symptoms during pregnancy.

Some experts report that almost 7% of first-degree female relatives of endometriosis patients also develop it. A family history of endometriosis not only puts women at high risk for the condition but possibly a more severe manifestation of it as well.

Women may also be at higher risk for endometriosis if they were born with uterine abnormalities that obstruct the normal outflow of blood and cause retrograde menstruation.

There have been reports of endometriosis developing after cesarean sections, including implants developing in surgical scars and in the urinary tract. Some experts believe endometriosis should be suspected in women with urinary tract symptoms and a history of cesarean section.

Various disorders occur in greater rates in women who have endometriosis. In some cases, these disorders and endometriosis may be caused by common factors, but it is not clear what they are.

They include:

Certain cancers, particularly for early-onset breast and ovarian cancers, non-Hodgkin's lymphomas, and melanoma.
Autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and multiple sclerosis. In all of these diseases, the immune system launches a destructive inflammatory response against the body's own cells (which differ in location depending on the disease). These are uncommon disorders, but in a major 2002 survey of women with endometriosis, they occurred in 12% of these women. This provides some support to the theory that endometriosis, too, is an autoimmune condition.
Hypothyroidism. In the same 2002 survey mentioned above, 42% of women had low thyroid or some other hormonal disorder.
Fibromyalgia and chronic fatigue syndrome. In the same survey, 31% reported one of these conditions.
Diabetes.
Allergies and asthma. Endometriosis is more prevalent in women with a family history of asthma and allergies, including food and skin allergies and hay fever.
Migraine. A small 2006 study suggested that women who have migraine headaches are at increased risk of endometriosis.

Some studies have reported a higher incidence of certain factors in women with endometriosis:

Women with endometriosis tend to be taller and thinner than average.
Women with red hair have an increased risk for endometriosis. Experts guess that the gene determining red hair might be located near other genes that make such women susceptible to endometriosis.

Alcohol and caffeine use have been associated with a higher risk.

Complications

Endometriosis is a chronic disease that is difficult to diagnose and treat. Without treatment, endometriosis gets progressively worse in 65 - 80% of patients. Even with treatment, endometriosis continues to advance in 20% of patients. Cysts and implants may grow and spread to other parts of the pelvis, and in very severe cases, to the urinary or intestinal tracts. Eventually adhesions may form. These are dense, web-like structures of scar tissue that can attach to nearby organs and cause pain, infertility, and intestinal obstruction.

Pain is the most common complaint for women with endometriosis, and it can significantly impair the quality of life. The pain experienced around menstruation can be so debilitating that up to 25% of women with the condition are incapacitated for 2 - 6 days of each month. In severe cases, regular activities may be curtailed for up to 2 weeks per month. Sleeping problems have been reported in 75% of patients, mostly due to pain.

Endometriosis may account for as many as 30% of infertility cases. Some evidence suggests that between 30 - 50% of women with endometriosis are infertile. Often, however, it is difficult to determine if endometriosis is the primary cause of infertility, particularly in women who have mild endometriosis. In an attempt to determine the chances for infertility with endometriosis, researchers have come up with a staging system based on findings during diagnostic surgery.

Endometriosis rarely causes an absolute inability to conceive, but it can contribute to infertility both directly and indirectly.

Direct Effect of Endometrial Cysts. Endometrial cysts may directly prevent infertility in a number of ways:

If implants occur in the fallopian tubes, they may block the egg's passage.
Implants that occur in the ovaries prevent the release of the egg.
Severe endometriosis can eventually form rigid webs of scar tissue (adhesions) between the uterus, ovaries, and fallopian tubes, thereby preventing the transfer of the egg to the tube.

Immune Factors and the Inflammatory Response. Researchers are focusing on defects in the immune system that not only may be responsible for endometriosis in the first place but also may cause the infertility associated with endometriosis. Even in early stage endometriosis, investigators have observed increased immune system activity. It is possible that in such cases, the body perceives these foreign endometrial implants as hostile, and launches an attack.

In this process, the body overproduces specific immune factors that contribute to infertility:

Cytokines. Cytokines are very potent immune factors that, when overproduced, cause damage and inflammation in the very regions that are directed to protect. Such damage could produce scarring and obstructions that interfere with implantation and development of a fertilized egg. In severe endometriosis, there is inflammation in the fluid surrounding the uterus, which could create a hostile environment for the sperm.
Prostaglandins. Elevated levels of these hormone-like factors not only produce inflammation but also increase uterine contractions. (Women with endometriosis have a higher than average risk for miscarriage.)
Other Immune Factors. Growth factors, which stimulate growth of new blood vessels, and toxins produced by implants may impair fertility.

Other Conditions Linking Endometriosis and Infertility. Researchers have noted unusually low levels of specific substances that enable a fertilized egg to adhere to the uterine lining. Such abnormalities are more often a factor in infertility in women with mild-to-moderate endometriosis than in those with severe cases.

One study found that the eggs in women with endometriosis appeared to have more genetic abnormalities than those in women without the disorder.

Implants can also occur in the bladder (although rare) and cause pain and even bleeding during urination. Implants also sometimes form in the intestine and cause painful bowel movements, constipation, or diarrhea. Hormonal treatments, the standard therapies for endometriosis, are not helpful in such cases, and surgery may be needed.

Endometriosis has characteristics that are similar to cancerous tumors, including cellular invasion of other tissues, unrestrained growth, development of new blood vessels, and impaired ability of cells to naturally self-destruct. It is not a malignant disease, however, but experts have been debating for years whether it represents any significant danger.

The possible risks for ovarian and endometrial cancers are of specific concern. Some researchers have identified certain genetic mutations that may transform endometrial cells into ovarian or endometrial cancers in rare cases. Some evidence suggests that ovarian cancer associated with endometriosis may differ from most ovarian cancer cases, and, in fact, have a better outlook.

Of additional concern are studies suggesting that women with endometriosis have a higher risk for other cancers, particularly for early-onset breast cancer and non-Hodgkin's lymphoma (NHL).

The emotional effect of severe endometriosis can be almost as devastating as the pain. It can affect marriage and work. In one survey conducted by the Endometriosis Association, patients reported the following emotional effects from this disease:

84% of patients reported feeling depressed during periods of pain
75% felt irritable
More than 50% reported feelings of anxiety and anger
About 20% said they felt hopeless

In one study, during the days around menstruation 30% of women with endometriosis increased their alcohol intake compared to 14% of women with other gynecological problems and only 9.5% of women with no gynecological disorders.

Diagnosis

Although endometriosis is the most commonly diagnosed uterine disorder, it is often misdiagnosed or missed altogether. In a study of women with proven endometriosis, more than half of them had been told by a doctor that nothing was wrong. In another study, half of women with endometriosis reported that they visited a doctor five or more times before they were diagnosed.

Endometriosis frequently begins to develop in adolescence, but it is not typically diagnosed until a woman is in her mid-20s or early 30s. There are a number of reasons for this:

The symptoms vary widely, and sometimes do not occur at all. Some women do not know they have endometriosis until they fail to become pregnant and seek help for infertility.
Pain in the pelvic or abdominal area can be caused by so many conditions that it is often difficult to pin down the precise cause.

Endometriosis should be highly suspected in women with severe menstrual cramps who are also infertile. Laparoscopy, an invasive diagnostic procedure, is the only definitive method for diagnosing endometriosis. However, a trial using one of several hormonal therapies is usually sufficient to confirm or rule out endometriosis. Such drugs include danazol, GnRH agonists, and progestins.

Many conditions cause pelvic pain. In many cases, the cause is unknown and it often resolves on its own. In one study, pelvic pain improved or resolved without treatment in 77% of women over a 15-month period. However, some causes of pelvic pain can be serious and should be ruled out during a work-up for endometriosis.

Primary Dysmenorrhea. Primary dysmenorrhea is recurrent pelvic pain associated with menstruation. Dysmenorrhea is common in many women. [See In-Depth Report #100: Menstrual disorders.]

Adenomyosis. A condition called adenomyosis occurs when nodules (knots) of endometrial tissue develop within the deep muscle layers of the uterus. This disorder is often classified with endometriosis, but adenomyosis is a different disease. (Endometriosis occurs when endometrial tissue grows and functions outside the uterus.) Adenomyosis is a significant cause of severe pelvic pain and menstrual irregularities. Until recently adenomyosis was diagnosed only after a hysterectomy, but advanced imaging techniques using ultrasound and magnetic resonance imaging scans may be able to detect it. A 2006 study indicated that women who have had surgery for endometriosis, yet continue to suffer from menstrual and pelvic pain, may actually have adenomyosis.

Adenomyosis typically occurs in women who have uterine fibroids, women age 40 - 50, and women who have had children. [See In-Depth Report #73: Uterine fibroids.]

Fibroid tumors may not need to be removed if they are not causing pain, bleeding excessively, or growing rapidly.

Other Causes of Pelvic Pain. Many conditions cause pelvic pain that may or may not be related to menstruation. Some causes of pelvic pain can be serious and should be ruled out:

Uterine fibroids
Pelvic inflammatory disease (which is a result of infections in the pelvic area)
Miscarriage
Ectopic pregnancy

Click the icon to see an image of an ectopic pregnancy.

Pelvic cancer (rare)
Uterine polyps
The use of an intrauterine device (IUD) for contraception

Conditions that may mimic symptoms of endometriosis but which are unrelated to problems in the reproductive organs include:

Severe kidney or urinary tract infections
Celiac disease
Appendicitis
Interstitial cystitis
Inflammatory bowel disease
Diverticulitis
Irritable bowel syndrome

The doctor may be able to feel tender masses or nodules during a pelvic examination, but these signs can indicate many conditions and do not necessarily mean endometriosis is present.

Laparoscopy. Diagnostic laparoscopy, an invasive surgical procedure, is currently the only definitive method for diagnosing endometriosis. Laparoscopy normally requires a general anesthetic, although the patient can go home the same day.

Click the icon to see an image of laparoscopy.

The procedure is as follows:

The surgeon makes tiny abdominal incisions through which a fiber optic tube, equipped with small camera lenses, is inserted. The doctor uses these devices to view the uterus, ovaries, tubes, and peritoneum (lining of the pelvis) on a video monitor.
Carbon dioxide gas is injected into the abdomen, distending it and pushing the bowel away so that the doctor has a wider view.
A blue dye may be flushed through the fallopian tubes to determine blockage; if there is an obstruction, the dye will not flow through the tube.
If the surgeon needs to remove small endometrial cysts or other lesions during the procedure (operative laparoscopy), tiny surgical instruments are passed through a tube.

The procedure is used for detecting and staging endometriosis to determine its severity. In some cases, the procedure itself will restore fertility in women with endometriosis.

Transvaginal Hydrolaparoscopy. Transvaginal hydrolaparoscopy is a new and less invasive approach than laparoscopy, since the instruments are inserted through the vagina, not through incisions in the abdomen. It requires only sedation, does not use CO2 to distend the abdomen, and has a much shorter and easier recovery than with standard laparoscopy. When used by a skilled professional, it is as accurate as laparoscopy, but is not yet widely available.

Hysteroscopy. Hysteroscopy is a procedure that may be used to detect the presence of fibroids, polyps, or other causes of bleeding. (It may miss cases of uterine cancer, however, and is not substitute for more invasive procedures, such as D&C or endometrial biopsy, if cancer is suspected.)

It is done in the office setting and requires no incisions. The procedure uses a long flexible or rigid tube called a hysteroscope, which is inserted into the vagina and through the cervix to reach the uterus. A fiber optic light source and a tiny camera in the tube allow the doctor to view the cavity. The uterus is filled with saline or carbon dioxide to inflate the cavity and provide better viewing. This can cause cramping.

Hysteroscopy is non-invasive, but 30% of women report severe pain with the procedure. The use of an anesthetic spray such as lidocaine may be highly effective in preventing pain from this procedure. Other complications include excessive fluid absorption, infection, and uterine perforation. Hysteroscopy is also used as part of surgical procedures.

An ultrasound is performed in cases where other conditions are suspected, such as uterine fibroids, ovarian cysts, or ectopic pregnancy. This non-invasive imaging technique can detect endometriomas, or cysts that are usually located on the ovaries and filled with thick dark blood. Ultrasound can also pick up cysts larger than 1 cm (about 1/3 inch), but will miss smaller cysts, or small and shallow endometrial implants on the surface of ovaries, or on the peritoneum (lining of the pelvis).

Once a diagnosis is made, more sophisticated imaging techniques, such as computed tomography (CT) scanning or magnetic resonance imaging (MRI), may be used to obtain a more accurate image of severe endometriosis.

Investigators are studying certain chemicals detected in blood tests that may prove to help diagnose endometriosis and so avoid invasive diagnostic procedures in many women. Among the most studied to date are CA-125 and CA19-9. Both are elevated in women with severe endometriosis. Higher levels of both chemicals occur in many other diseases, however, including ovarian cancer, so results using this test alone do not provide enough information for a definitive diagnosis of endometriosis.

During laparoscopy, the surgeon determines the number, size, and location of endometrial implants and adhesions. This information helps rank endometriosis by the extent of the disease and give the likelihood of infertility:

Minimal (stage I)
Mild (stage II)
Moderate (stage III)
Severe (stage IV)

A number of experts do not believe these categories are useful, because they often do not relate to the intensity of the pain, or to treatment success rates.

Some experts believe it is more accurate to further categorize endometriosis by the depth of penetration:

Superficial Endometriosis. Endometriosis that lies more on the surface is more highly associated with infertility than deep implants.
Infiltrative Endometriosis. Implants deeper than 5 - 6 mm; deep implants are believed to be the best indicator of progression and severe symptoms.

Treatment

There is no perfect way of managing endometriosis. The three basic treatment approaches are:

Watchful waiting (to relieve symptoms)
Hormonal therapy (to reduce endometrial implants)
Surgery (to reduce endometrial implants, restore fertility, or possibly cure the condition)

The choice depends on a number of factors, including the woman's symptoms, her age, whether fertility is a factor, and the severity of the disease.

In general, watchful waiting is a good initial choice for:

Women with mild pain who, if fertile, do not wish to become pregnant. If women with mild endometriosis wish to become pregnant, the doctor may recommend unprotected sex for 6 months to year. If pregnancy does not occur, then treatment may be started.
Women approaching menopause.

Some experts believe that early diagnosis and treatment in young women without symptoms might prevent some cases of infertility later on. Unfortunately, however, some treatments for endometriosis may actually trigger symptoms in those who do not yet experience them.

Hormone therapies are used to mimic states in which ovulation does not occur (such as pregnancy or menopause) or to directly block ovulation. Hormonal drugs include oral contraceptives, progestins, GnRH agonists, and danazol. They can be very effective in relieving endometriosis symptoms. Some of these drugs may also be used after surgery to help prevent recurrence of endometriosis. There is also some evidence that GnRH agonists and danazol may improve immune factors associated with endometriosis. But there are downsides:

None of these drugs can cure the problem. Symptoms recur in about half of patients within 5 years of treatment.
They do not improve fertility rates and may delay conception in women who use them.
Side effects of these drugs can be distressing. There is a high dropout rate with the use of nearly all these hormonal treatments.
Women who take GnRH agonists, danazol, or similar drugs should use non-hormonal birth control methods (such as the diaphragm, cervical cap, or condoms) because these drugs can increase the risk for birth defects.

Surgery is an option for the following women:

Women with severe pain that does not respond to watchful waiting and medical treatment.
Women who want to become pregnant and endometriosis is most likely the major contributor to infertility.

There are two basic surgical approaches for endometriosis:

Conservative Surgery (Laparoscopy or Laparotomy). Conservative surgery uses laparotomy or laparoscopy to remove the endometriosis implants without removing any other reproductive organs. It is a good option for women who wish to become pregnant or who cannot tolerate hormone therapy. Some experts believe that laparoscopy surgery should be the treatment of choice for women with endometriosis. Endometriosis often recurs after conservative surgery, however. Recurrence rates at 2 years range from 2 - 47%. The risk for recurrence or residual pain after any procedure increases with the severity of the condition, particularly if endometriosis has affected areas outside the uterus.
Radical Surgical Therapy (Hysterectomy). Hysterectomy with removal of ovaries (oophorectomy) along with all endometrial implants is the only potential cure for endometriosis. If endometriosis has developed outside the uterus than even this procedure is not curative. Removing only the uterus with hysterectomy, in any case, has the same risk for recurrence as conservative surgery.

Click the icon to see an illustrated series detailing hysterectomy.

In choosing between hysterectomy (with or without oophorectomy) and conservative surgeries, age and the desire for children are important factors. One study reported a greater sense of loss, more residual symptoms, and more pain in younger women (under age 30) who have undergone hysterectomy than in older women. In one study, 37% of such younger women regretted their decision to have a hysterectomy.

Once careful instruction is given for all the risks and benefits of the different surgical options, the doctor must respect any decision a patient makes to retain as much of her reproductive system as she wants, even if she is past menopause. Both the patient and the doctor should also be clear about the possibility of changing procedures once the operation has begun, depending on what the surgeon may observe. For example, the surgeon may find abnormalities that require more extensive surgery.

Much of the success of any procedure relies on the experience of the surgeon. A woman should always ask for a doctor's track record, or the number of times the doctor has performed the procedure in question. The more, the better. Asking for complication rates may be helpful, but a patient should realize that an experienced surgeon may have a higher number of high-risk patients, and therefore, a higher complication rate than a less experienced surgeon with fewer serious cases.

For women with severe endometriosis who want to become pregnant, conservative surgery (typically laparoscopy) is the appropriate approach for restoring fertility. Hormonal therapies that treat endometriosis itself, such as GnRH agonist or progestins, are generally considered not to help fertility. However, a 2002 study suggested that the use of the GnRH agonists after surgery helped improve conception rates in women who subsequently undergo assisted reproductive techniques (ART), such as in vitro fertilization (IVF). A 2006 study indicated that GnRH agonists given along with infertility treatments may help improve a woman's chance of becoming pregnant. This research is still preliminary.

In any case, ART and hyperstimulation of the ovary using fertility drugs to produce eggs are the standard fertility treatments available to women if surgery fails. ART includes techniques such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Hyperstimulation is the less expensive approach. In a 2003 study, however, ART achieved much greater conception rates in women with endometriosis, particularly those with late-stage disease.

It is not clear whether women with early -stage endometriosis do any better with fertility treatment than simply trying to become pregnant through non-aggressive means. Women with endometriosis who are trying to conceive should discuss all treatment options with a specialist. [See In-Depth Report #22: Infertility in women.]

Lifestyle Changes

Some women report relief by avoiding dairy products and having a diet rich in fiber and low in saturated (animal) fats. Fiber-rich foods (such as fruits and vegetables) along with plenty of fluids (water or juice, not caffeine) are not only healthy but help prevent constipation, which can intensify symptoms. If women choose a diet that limits dairy products, they should be sure to have sufficient calcium from other sources.

A 2005 study involving over 500 women reported that red meat and ham consumption increased the risk for endometriosis. Diets high in green vegetables and fresh fruit appeared to protect against it.

Fat compounds called omega-3 fatty acids may have specific anti-inflammatory effects. They are found in certain oily fish (sardines, mackerel) and can be obtained in supplements. Supplements may be labeled either omega-3 fatty acids or EPA-DHA (which are the important compounds). Evening primrose oil and black currant oil, found in health food stores, contain similar fatty acids that may be helpful. However, food sources are the healthier choice.

Omega-3 fatty acids, found plentifully in oily fish and flaxseed and canola oils, are beneficial to people who have IBD (inflammatory bowel disease).

Drinking alcohol and and smoking cigarettes may increase endometriosis risk. It is unclear whether caffeine is a significant risk factor.

A sitz bath is simply sitting in a basin of water. Some people report relief by alternating between sitting 3 minutes in a hot water basin and then 1 minute in a cold water basin. This is repeated three times. The procedure is performed twice a day 3 - 4 days a week, except during menstruation.

A warm bath or application of heated abdominal pad may help relieve painful menstrual cramps.

Kegel exercises are designed to strengthen the muscles of the pelvic floor that both support the bladder and close the sphincters. Some people find they help endometriosis. The exercises consist of tightening and releasing the pelvic muscle. Since the muscle is internal and sometimes difficult to isolate, doctors often recommend practicing while urinating on the toilet. The patient tries to contract the muscle until the flow of urine is slowed or stopped and then releases it. (However, once learned, Kegel exercises should not be regularly performed while urinating as this practice may eventually weaken the muscles.)

Exercise may be very helpful for women with endometriosis. It relieves stress and tension and may reduce hormonal levels that can contribute to endometrial growth.

Acupuncture and Acupressure. Some studies have reported relief from pelvic pain after acupuncture or acupressure, a technique that applies small pins or pressure to specific points on the body. Some women report relief with reflexology, a technique that uses manual pressure on acupuncture points on the ears, hands, and feet.

Transcutaneous Electrical Nerve Stimulation. Transcutaneous electric nerve stimulation (TENS) applies electrodes to certain parts of the body and administers low-level electrical pulses to those locations. Research suggests that it works by altering the body's ability to receive pain signals. The standard approach is to give 80 - 100 pulses per second, for 45 minutes, three times a day. TENS is painless and patients are barely aware of the sensation. A 2002 analysis suggested that this approach may help some women with dysmenorrhea.

Yoga and Meditative Techniques. Yoga and meditative techniques that promote relaxation may also be helpful for menstrual cramps.

Chiropractic. Some women with primary dysmenorrhea have sought help from chiropractors trained in spinal manipulation. One study compared a high-force spinal manipulation technique with a low-force maneuver used as a placebo technique. Both showed lower scores on tests that measure pain, perhaps indicating that a simple back rub by a sympathetic partner or friend may be helpful.

Herbal and Other So-Called Natural Remedies for Cramp Relief. Researchers have not conducted many rigorous studies on herbal remedies for menstrual and pelvic pain. Small studies have suggested that pycnogenol, a plant extract derived from the bark of the French maritime pine tree, may help reduce endometriosis symptoms. Some patients have reported relief from menstrual cramps with aromatherapy using lavender, sage, and rose oils.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Medications

The basic approach in hormonal treatments for endometriosis is to block production of female hormones (estrogen and progesterone) or to prevent ovulation. Hormonal drugs are used for pain relief only. None have been proven to improve fertility rates and in some cases may delay conception. Specific hormonal drugs may have different effects for women with endometriosis.

Inducing Pseudopregnancy. Oral contraceptives that contain estrogen and progestins mimic a pregnant state and block ovulation. (Progestins are natural or synthetic forms of progesterone). Progestins may also be used alone, since they have specific effects that can cause the endometrial tissue itself to atrophy.
Inducing Pseudomenopause. Gonadotropin-releasing hormone (GnRH) agonists or gestrinone, an anti-progesterone that mimic menopause. They reduce estrogen and progesterone to their lowest level.
Inducing On-going Blockage of Ovulation. Danazol, a derivative of male hormones, is a powerful ovulation blocker.

Studies report that around 80% of women achieve pain relief after taking these drugs. To date, comparison studies have found few differences in effectiveness among the major hormonal treatments. Differences occur mostly in their side effects. Women should discuss the effects of particular medications with their doctors to determine the best choice.

Oral contraceptives (OCs), commonly called "the Pill," contain combinations of an estrogen and a progestin (either a natural progesterone or the synthetic form called progestin). For some patients, OCs may provide better endometriosis pain relief than gonadotropin releasing hormone agonist drugs. OCs may reduce the risk of ovarian cancer by 30 - 50% and of endometrial cancer by 50%, a potentially important benefit in women with endometriosis. Patch contraceptives are available, but they may increase the risk for menstrual cramping.

Click the icon to see an illustrated series detailing the birth control pill.

When used throughout a menstrual cycle, OCs suppress the actions of other reproductive hormones (luteinizing hormone, or LH, and follicle stimulating hormone, or FSH) and prevent ovulation. There are many brands available. The estrogen compound used in most oral contraceptives is estradiol. Many different progestins are used, and there are many brands. None to date have proven to be superior over others. Women should discuss the best options for their individual situations with their doctor.

Standard OCs come in a 28-pill pack that contains 21 active pills and 7 inactive pills. Newer “continuous-dosing” (also called “continuous-use”) oral contraceptives aim to reduce -- or even eliminate -- monthly periods and thereby prevent the pain and discomfort that often accompanies menstruation. These OCs contain a combination of estradiol and the progesterone levonorgestrel, but use extending dosing of active pills.

Seasonale, the first continuous-dosing contraceptive, was approved in 2003. It contains 81 days of active pills followed by 7 days of inactive pills. Women who take Seasonale have on average a period every 3 months. Seasonique, a follow-up to Seasonale, was approved in 2006. As with Seasonale, it produces about 4 periods a year. With Seasonique, a woman takes 84 days of levonorgestrol-estradiol pills followed by 7 days of pills that contain only low-dose estradiol.

In 2007, the FDA approved Lybrel, which supplies a daily low dose of levonorgestrel and estradiol with no inactive pills. Because Lybrel contains only active pills, which are taken 365 days a year, it completely eliminates monthly menstrual periods. In clinical trials, 59% of women who took Lybrel completely stopped menstrual periods by the end of the first year. Some women, however, experienced occasional unscheduled bleeding or spotting during the first 3 - 6 months.

Estrogen and progestin each cause different side effects. The most serious side effects are due to the estrogen in the combined pill. Uncommon but more dangerous complications of OCs include high blood pressure and deep-vein blood clots (thrombosis), which may contribute to heart attack or stroke. Studies have been conflicting about whether estrogen in oral contraception increases the chances for breast cancer and, if it does, which women are at risk.

Progestins alone may be helpful and are the oldest drugs used for endometriosis. Progestins can prevent ovulation and reduce the risk for endometriosis in the following ways:

They block luteinizing hormone (LH), one of the reproductive hormones important in ovulation.
They change the lining of the uterus and eventually cause it to atrophy.
They may provide pain relief equivalent to the more powerful hormone drugs. Some experts recommend them as the first choice for women with endometriosis who do not want to become pregnant.

Specific Progestins. Progestins are available in pill or injectable form, or as a progestin-releasing intrauterine device (IUD). Medroxyprogesterone (Depo-Provera), which is administered by injection every 3 months, is one of the standard progestins used. A new low-dose formulation, Depo-subQ Provera 104, was approved in 2005. Oral progestins include norethindrone (Micronor, Aygestin, Norlutate). Norethindrone is also known as norethisterone.

A 2006 study compared low-dose depot medroxyprogesterone with the gonadotropin releasing hormone (GnRH) agonist leuprolide (Lupron). The two drugs worked equally well in controlling endometriosis pain. However, leuprolide caused more loss of bone mineral density, a condition associated with osteoporosis. Patients who received medroxyprogesterone injections had fewer hot flashes than those who received leuprolide, but they had more episodes of bleeding and spotting.

Progestin-releasing IUDs can be very helpful for many women with endometriosis, particularly an advanced version called the levonorgestrel-releasing intrauterine system, or LNG-IUS (Mirena). Studies suggest that the LNG-IUS reduces endometrial cell proliferation and increases cell self-destruction. Progestin released by the IUD mainly affects the uterus and cervix and causes fewer widespread side effects than other forms of progestins.

The LNG-IUS has proved effective for heavy bleeding (menorrhagia), and studies indicate that it helps control the symptoms of minimal-to-moderate endometriosis. Studies indicate that the LNG-IUS works as well as GnRH agonists in managing endometriosis pain, and causes less loss of estrogen. Some experts think that the LNG-IUS could become the treatment of choice for women with endometriosis pelvic pain who do not wish to become pregnant.

Side Effects of Progestins. Side effects of progestin occur in both the combination oral contraceptives and any contraceptive that uses only progestin, although they may be less or more severe depending on the form and dosage of the contraceptive. Side effects may include:

Changes in uterine bleeding, such as higher amounts during periods, spotting and bleeding between periods (called break-through bleeding), or absence of periods
Unexpected flow of breast milk
Abdominal pain or cramps
Diarrhea
Fatigue, unusual tiredness, weakness
Hot flashes
Decreased sex drive
Nausea
Trouble sleeping
Acne or skin rash (although low-dose OCs actually improve acne)
Depression, irritability, or other mood changes
Swelling in the face, ankles, or feet
Weight gain

Newer formulations of combination pills that use low-dose estrogen and newer progestins may reduce and even avoid many of these side effects. Progestins used in non-oral contraceptives, such as the LNG-IUS IUD, also may not pose as high a risk for these side effects. If side effects persist or are severe, a woman should always talk to her doctor. Many women do not experience these side effects, or if they do, their bodies eventually adjust.

Gonadotropin releasing hormone (GnRH) agonists are effective hormone treatments for endometriosis. They are able to block the release of the reproductive hormones LH (luteinizing hormone) and FSH (follicular-stimulating hormone). As a result, the ovaries stop ovulating and no longer produce estrogen. Ovulation and menstruation resume around 4 - 10 weeks after stopping the drug. The specific length of time depends on the type of GnRH agonist used.

Women with endometriosis often have a difficult time getting pregnant. A 2006 review suggested that GnRH agonists may help women with endometriosis become pregnant when the drug is given along with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). (IVF and ICSI are standard infertility treatments.) The review found that 3 - 6 months of GnRH therapy in combination with infertility treatment quadrupled the pregnancy rate. However, the study did not supply data on how many women actually gave birth. In addition, there is not enough information on whether these drugs may adversely affect a woman or her fetus.

Specific GnRH Agonists. GnRH agonists include goserelin (Zoladex), buserelin, a monthly injection of leuprolide (depot Lupron), and a nasal spray, Nafarelin (Synarel). Studies have reported that nafarelin shrank all implants and significantly relieved symptoms in 85% of patients, delayed recurrence of endometriosis after surgery, and in comparison with leuprolide, was less expensive, had fewer side effects, and a provided better quality of life.

Side Effects and Complications. Commonly reported side effects (which can be severe in some women) include menopause-like symptoms that include hot flashes, night sweat, and changes in the vagina, weight change, and depression. The side effects vary in intensity depending on the GnRH agonist. They may be more intense with leuprolide and persist after the drug has been stopped.

The most important concern is possible osteoporosis from estrogen loss. Women ordinarily should not take GnRH agonists for more than 6 months. Certain approaches may preserve enough estrogen to protect bones and still effectively relieve endometriosis symptoms:

Add-back therapy provides doses of estrogen and progestin that are high enough to maintain bone density, but are too low to offset the beneficial effects of the GnRH agonist. Studies suggest this is safe and effective for protecting bone.
Intermittent leuprolide uses repeated 6-month courses of GnRH agonists followed by an average of 9 months of symptom control only.
Taking GnRH agonists in very low doses is an alternate approach, but is still largely untested.
Adding bone-protective drugs may be helpful. The standard ones are bisphosphonates and include alendronate (Fosamax), risedronate (Actonel), and etidronate (Didronel). Other drugs are being tested in combination with a GnRH agonist to preserve bone. They include the parathyroid hormone teriparatide (Forteo) and selective estrogen-receptor modulators (SERMs), such as raloxifene (Evista).

GnRH treatments used alone do not prevent pregnancy. Furthermore, if a woman becomes pregnant during their use, there is some risk for birth defects. Women who are taking GnRH agonists should use non-hormonal birth control methods, such as the diaphragm, cervical cap, or condoms while on the treatments.

Danazol (Danocrine) is a synthetic drug that resembles a male hormone (androgen). It suppresses the pathway leading to ovulation. Studies have shown symptomatic improvement in 90% of women, although in one study, only about 58% of women expressed satisfaction with this therapy. A high drop-out rate occurs, most often because of adverse side effects, particularly male characteristics, such as growth of facial hair, acne, weight gain, dandruff and deepening of the voice.

Danazol may increase the risk for unhealthy cholesterol levels. A few cases of blood clots and strokes have also been reported, as well as rare cases of liver damage. One study reported that taking a low dose may relieve endometrial symptoms and reduce the risk for these side effects. Exercise may also help reduce side effects. As with GnRH drugs, pregnant women or those trying to become pregnant should not take this drug because it may cause birth defects.

Antiprogestins are promising drugs for endometriosis because they reduce both estrogen and progesterone receptors.

Gestrinone. Gestrinone is the most studied antiprogestin and appears comparable to GnRH agonists in reducing pain and while causing fewer menopausal symptoms. In one study, bone density even increased slightly. Adverse effects of gestrinone include male hormone symptoms, such as acne, and possibly the development of unhealthy cholesterol levels.

Mifepristone. Mifepristone (Mifeprex) is another antiprogestin that may be helpful for treating endometriosis. In one 6-month study, mifepristone improved symptoms and reduced endometrial implants without causing menopausal side effects. Long-term use, however, may cause changes in the uterine tissue and cell proliferation.

Nonsteroidal Anti-inflammatory Drugs (NSAIDs). Over-the-counter NSAIDs may be sufficient for about 75% of women with endometrial pain. NSAIDs block prostaglandins (the substances that increase uterine contractions). They are effective painkillers and also have other properties that act against inflammatory factors. Aspirin is the most common NSAID, but there are dozens of others available over the counter or by prescription. Among the most effective NSAIDs for menstrual disorders are ibuprofen (Advil, Motrin, Midol PMS), naproxen (Aleve, Naprosyn, Naprelan, Anaprox), and mefenamic acid (Ponstel). For maximum benefit, they should be taken 7 - 10 days before a period is expected. However, long-term use of NSAIDs can increase the risk for gastrointestinal bleeding and ulcers. One study of women with iron deficiency anemia reported that overuse of NSAIDs for menstrual disorders contributes to anemia.

Acetaminophen. Acetaminophen (Tylenol) reduces levels of female hormones (gonadotropins and estradiol, an estrogen), which may have some beneficial effect on menstrual disorders. A combination of acetaminophen and pamabrom (Women's Tylenol Menstrual Relief) is specifically aimed at treating menstrual pain and bloating. (Pamabrom is a diuretic, a drug used to reduce fluid build-up and bloating.)

Opioids. Drugs containing codeine should not generally be used for endometriosis pain management. They can cause pelvic congestion and constipation, which can worsen symptoms in patients with gastrointestinal distress.

GnRH Antagonists. GnRH antagonists include ganirelix (Antagon) and cetrorelix (Cetrotide). These newer drugs differ from GnRH agonists in that they have a direct effect on the pituitary gland. The result is quicker action. They also pose a lower risk for complications and side effects.

Aromatase Inhibitors.Drugs that inhibit aromatase, an enzyme that is a major source of estrogen, are being studied for effects against endometriosis. Such drugs include anastrozole, letrozole, exemestane, and vorozole. Aromatase levels may be abnormal in women with endometriosis. A 2004 pilot study of letrozole combined with a progestin showed reduction of endometriosis as well as decrease in pelvic pain, suggesting that this treatment holds promise.

Selective Estrogen-Receptor Modulators (SERMs). Drugs known as selective estrogen-receptor modulators (SERMs) are thought to act like estrogen in some tissues but behave like estrogen blockers (antiestrogens) in others. They have not been widely studied for endometriosis since tamoxifen (Nolvadex), the most commonly used SERM, may worsen endometriosis. However, the actions of other SERMs, such as raloxifene (Evista) or tibolone (only available in Europe), may be beneficial and warrant more research.

Selective Progesterone Receptor Modulators (SPRMs). SPRMs, also called mesoprogestins, have both agonist and antagonist properties. This new class of drugs may be effective for suppressing endometrial growth.

Other investigational drugs for treatment of endometriosis include tumor necrosis factor alpha (TNF-alpha) inhibitors, angiogenesis inhibitors, and various immune modulators.

Conservative Surgery

The goal of conservative surgery is to aggressively remove as many endometrial implants and cysts as possible without causing surgical scarring and subsequent adhesions that could cause fertility problems. The two conservative procedures used are either laparoscopy or laparotomy.

Improving Fertility. Surgery has been shown to improve infertility rates in women with severe endometriosis (stages III and IV). Whether it offers any advantage in pregnancy rates in women with mild-to-moderate endometriosis (stage I or II) is unclear. Nevertheless, some doctors recommend conservative surgery even in early-stage endometriosis, because of the progressive nature of the disorder some evidence suggests it improves fertility. Fertility can often be restored even if the surgery does not remove all the endometrial implants. However, the best fertility rates in such cases occur in the early postoperative period. They decline over time if implants have not been completely eliminated. Subsequent surgeries become less effective in restoring fertility.

Reducing Pain and its Recurrence. Studies report pain reduction after surgery in more than 60% of women. Conservative surgery, however, can miss microscopic implants that may continue to cause pain and other symptoms after the procedure.

Even with very successful surgery, endometriosis usually recurs within a period of between 2 months and several years. In one study, the risk for recurrence after conservative surgery was highest in women who have had previous surgery or who have stage IV disease (large endometriotic cysts). Other factors including age, pregnancy, or the number of cysts, did not seem to influence the degree of risk. An earlier study indicated that women who became pregnant after surgery for endometriosis had a lower risk for recurrence, but pregnancy itself does not cure endometriosis. The use of GnRH agonists after surgery may delay recurrence without affecting fertility.

Both laparoscopy and laparotomy are effective, but there are differences. Some experts believe that laparoscopy surgery should be the treatment of choice for women with endometriosis.

Laparoscopy is currently the gold standard treatment for endometriosis. It is usually done under general anesthetic and involves the following:

Carbon dioxide gas is injected into the abdomen, distending it and pushing the bowel away so that the doctor has a wider view.
The procedure requires making small incisions at the navel and above the pubic bone.
The laparoscope (a hollow tube equipped with camera lenses and a fiber optic light source) is inserted through the incision at the navel (the umbilical incision).
A probe is then inserted through the second incision, allowing the doctor to directly view the outside surface of the uterus, fallopian tubes, and ovaries.
One or two additional small incisions can be made on either side of the lower abdomen through these incisions. Surgical instruments or other devices are passed through these accessory incisions to destroy or remove abnormal tissue. Implants can be removed by excision (surgical removal) using a laser or scissors or by destroying the area with lasers or with electricity (or electrocautery).

In one study, laparoscopy achieved pain relief in over 62% of women. A more recent study conducted 3 - 12 months post-surgery in women with severe (stage III/IV) endometriosis suggested 88% of patients were satisfied with the procedure.

In addition, pregnancy rates can range from 20% to over 50% after laparoscopy. (The procedure does not reduce the chances for pregnancy in women who must still undergo assisted reproductive techniques to conceive.) Still, recurrence rates for laparoscopy are no better than those with laparotomy -- the more invasive procedure.

Laparotomy uses a wide abdominal incision and conventional surgical instruments. It is more invasive and requires a longer recovery time. In some severe cases, the doctor may need a wider view of the pelvic area and will perform this procedure. Laparotomy is typically used for infiltrating endometriosis, although the less invasive laparoscopy is showing increasing effectiveness, even for deep implants.

Complications after Surgery. Many patients experience temporary but severe discomfort in the shoulders after laparoscopy due to residual carbon dioxide gas that puts pressure on the diaphragm. The incisions, even with laparoscopy, may cause pain afterward, which can usually be treated effectively with mild pain relievers. There are small risks for bleeding, infection, and reaction to anesthesia. Surgery in the pelvic area may also cause scarring, which may cause pain and interfere with fertility.

Preoperative Drug Treatment. Hormonal drugs administered before laparoscopy and laparotomy are being investigated to reduce the size of endometrial cysts and so perhaps to improve outlook. A 2000 study, for example, reported that the GnRH agonist goserelin injected monthly 12 weeks before laparoscopy resulted in much smaller implants and better treatment of the disease than treatment with surgery alone.

Postoperative Drug Treatment. A number of studies have also been conducted to determine if taking hormonal drugs after surgery can provide further pain relief. Results have been mixed, and the benefits, if any, are probably slight.

Some evidence suggests that surgically cutting the pain-conducting nerve fibers leading from the uterus diminishes the pain from dysmenorrhea. Two procedures, uterine nerve ablation and laparoscopic presacral neurectomy, can block such nerves. Small studies have shown benefits from these procedures, but stronger evidence is needed before they can be recommended for women with severe primary dysmenorrhea.

Laparoscopic Uterosacral Nerve Ablation (LUNA). LUNA is a recent approach that uses either laser or cauterization to destroy nerves in a small segment of the ligaments that connect the cervix with the lower back. The ligaments do not appear to provide any structural support. There are few side effects from the procedure. The patient does not lose any sensations associated with sexual activity.

Laparoscopic Presacral Neurectomy (LPSN). LPSN uses laser techniques to sever a web of nerves between the lower spine and tail bone that transmit pain from the uterus. The procedure does not affect fertility. Studies suggest that it may work better than LUNA in the long term, but it also poses a higher risk of complications. These complications include constipation, diarrhea, and urinary problems. However, many women find that these symptoms eventually improve.

Hysterectomy

Hysterectomy, the surgical removal of the uterus, is the second most frequently performed surgery in premenopausal women (Cesarean sections are first). About 600,000 hysterectomies are performed each year in the U.S., which is among the highest rate of all countries. By age 60, about a third of American women have had this procedure. The highest hysterectomy rates are in women age 40 - 44. Women in the southern and midwestern areas of the United States are more likely to have the operation than those in the northeast and west.

A 2007 study suggested that a combination of factors predicts whether a woman will decide to have a hysterectomy. A woman who meets all three of these factors has a 95% chance of having a hysterectomy:

Presence of symptoms (pelvic pain, bleeding, symptomatic fibroids)
Lack of symptom improvement or resolution despite treatment
Previous use of GnRH agonist drugs

The number of procedures has continued to increase, but only slightly in recent years. Endometriosis accounts for 18% of these procedures, but the rates vary widely by ethnic group, with the great majority of endometriosis-related hysterectomies performed in Caucasian women.

Hysterectomy does not necessarily cure endometriosis. One study reported that endometriosis reappeared in 13% of women within 3 years of a hysterectomy and in 40% after 5 years.

Most women are satisfied with the procedure. A major analysis of evidence on hysterectomies reported that symptoms related to menstrual problems decline significantly in most women, although none completely disappear for all women. The majority of women also experience improved quality of life and emotional functioning. Women who have a hysterectomy are less likely to experience hot flashes than women who have a natural menopause.

Still, one study suggested that 70% of recommendations for hysterectomies did not meet the standard of care as determined by expert groups. In such cases, patients were not given alternative choices or adequate diagnostic evaluations. Any woman, even one who has reached menopause, who is uncertain about a recommendation for a hysterectomy should certainly seek a second opinion.

Once a decision for a hysterectomy has been made, the patient should discuss with her doctor what will be removed. The common choices are:

Total Hysterectomy (Removal of uterus and cervix). Removing only the uterus with hysterectomy has the same risk for recurrence as conservative surgery.
Supracervical Hysterectomy (Removal of uterus and preservation of the cervix). Procedure is performed in about 20 - 25% of cases.
Bilateral Salpingo-Oophorectomy (Removal of the fallopian tubes and ovaries). It can be used with either total or supracervical hysterectomy. This is the only potential cure for endometriosis. If endometriosis has developed outside the uterus then even this procedure is not curative.

Hysterectomy is surgical removal of the uterus, resulting in inability to become pregnant. This surgery may be done for a variety of reasons including, but not restricted to, chronic pelvic inflammatory disease, uterine fibroids and cancer. A hysterectomy may be done through an abdominal or a vaginal incision.

Total Hysterectomy. In a total hysterectomy the uterus and cervix are removed; this eliminates the risk of uterine and cervical cancer. (Given technical advances and growing surgical experience, a total hysterectomy may eventually be unnecessary except in special circumstances, such as when cancer is present.)

Supracervical Hysterectomy. In a supracervical hysterectomy (also called subtotal hysterectomy), only the uterus is removed. Retaining the cervix helps support the pelvic floor and may help maintain full sexual sensation, but the risk for cervical cancer remains. Women may experience cyclical bleeding for up to a year after surgery.

Bilateral Oophorectomy. Bilateral oophorectomy is the removal of both ovaries. (When only one ovary is removed, the procedure is called oophorectomy.) Bilatera salpingo-oophorectomy is the removal of both fallopian tubes plus both ovaries. These procedures may be performed with either total or supracervical hysterectomy. When a woman decides to have her ovaries removed, she should be aware of both the positive and negative consequences.

Oophorectomy significantly reduces the rates of re-operation and endometrial pain recurrence compared to hysterectomy alone. By removing the ovaries, oophorectomy causes estrogen loss and helps to reduce the risk for ovarian cancer and breast cancer. Premenopausal women should realize, however, that oophorectomy causes immediate menopause, which poses a risk for a number of health problems. These problems include osteoporosis, heart disease, skin wrinkling, and reduction in muscle tone. Estrogen replacement can help offset them. Women who have a bilateral oophorectomy and do not receive hormone replacement therapy may experience more severe hot flashes than women who enter menopause naturally.

There is still a further choice, which is whether the hysterectomy should be performed through an incision in the abdomen or through the vagina. A variant of vaginal hysterectomy, called laparoscopic-assisted vaginal hysterectomy (LAVH), is yet another option.

Abdominal Hysterectomy. Abdominal hysterectomy is the most common procedure and is used in over 80% of hysterectomies in African-American women and about 60% in Caucasian and other ethnic groups. With the abdominal procedure, a wide incision is required to open the abdominal area, from which the surgeon removes the uterus. If possible, the incision should cut horizontally across the top of the pubic hairline (called a bikini incision). This incision heals faster and is less noticeable than a vertical incision, which is used in more complicated cases. The patient may need to remain in the hospital for 3 - 4 days, and recuperation at home takes about 4 - 6 weeks.

Vaginal Hysterectomy. Vaginal hysterectomy requires only a vaginal incision through which the uterus is removed. It is used in less than 20% of cases in African-American women and slightly under 40% among Caucasian and other groups.

A variation of the vaginal approach is called laparoscopic-assisted vaginal hysterectomy (LAVH). It uses several small abdominal incisions through which the surgeon severs the attachments to the uterus and ovaries. They can then be removed through the vaginal incision, as in the standard approach. Hospitalization stays may be longer and costs are greater than with standard vaginal hysterectomy. The use of LAVH has risen significantly and is now employed in over a quarter of vaginal procedures. LAVH is very costly, however, and some experts question whether it adds any significant benefits compared to the standard vaginal procedure.

If possible, a patient should ask a family member or friend to help out for the first few days at home. The following are some of the precautions and tips for postoperative care:

For a day or two after surgery, the patient is given medications to prevent nausea and painkillers to relieve pain at the incision site.
As soon as the doctor recommends it, usually within a day of the operation, the patient should get up and walk in order to help prevent pneumonia, reduce the risk of blood-clot formation, and to hasten recovery.
Walking and slow, deep breathing exercises may help to relieve gas pains, which can cause major distress for the first few days.
Coughing can cause pain, which may be reduced by holding a pillow over a surgical abdominal wound or by crossing the legs after vaginal surgery.
Patients are advised not to lift heavy objects, not to douche or take baths, and not to climb stairs or drive for several weeks.
For the first few days after surgery, many women weep frequently and unexpectedly. These mood swings may be due to depression from the loss of reproductive capabilities and form abrupt changes in hormones, particularly if the ovaries have been removed.

The patient should discuss with the doctor when they can start exercise programs that more intense than walking. The abdominal muscles are important for supporting the upper body, and recovering strength may take a long time. Even after the wound has healed, the patient may experience an on-going feeling of overall weakness, which can be demoralizing, particularly in women used to physical health. Some women do not feel completely well for as long as a year; others may recover in only a few weeks.

Minor complications after hysterectomy are very common. About half of women develop minor and treatable urinary tract infections. There is usually mild pain and light vaginal bleeding post operation. The infrequent occurrence of severe bleeding or hemorrhaging after vaginal hysterectomy, or laparoscopic-assisted vaginal hysterectomy, may be promptly treated by laparoscopy.

More serious complications, such as those described below, are uncommon, but patients should be aware of their symptoms and call the doctor immediately if they occur.

Among the three procedures, a 2001 study reported that complication rates were 44% for abdominal hysterectomy, 24% for vaginal hysterectomy, and only 2% for LAVH. (LAVH is used in less than 4% of hysterectomies, however.)

Infection. Infection occurs in 10 - 15% of patients, the risk being higher with abdominal than with vaginal surgery. Risk factors for infection appear to be obesity, a longer than normal operative time, and low socioeconomic status. Patients should be aware of any symptoms and call the doctor immediately if they occur:

Continuing or increasingly severe pain
Fever
Heavy discharge
Bleeding (antibiotics given at the time of surgery help to reduce this risk)

Blood Clots. There is a slight risk for small blood clots, usually in veins of the legs (thrombophlebitis). A sudden swelling or discoloration in the leg can indicate this condition and require immediate medical attention.

Other Serious Complications. Other serious and even life-threatening complications are rare but can include:

Pulmonary embolism (blood clots that travel to the lung)

Surgical injury of the urinary or intestinal tracts.
Abscesses.
Perforation of the bowel.
Fistulas (a passage that bores from an organ to the skin or to another organ).
Dehiscence (opening of the surgical wound).

Long-Term Complications. Women who have had a total hysterectomy are at higher risk for the following long-term complications:

Muscle weakness in the pelvic area.
Prolapse (descent) of the bladder, vagina, and rectum if the muscle’s walls are overly weakened; may require further surgery.
Bowel problems may develop if adhesions (extensive scarring) have formed and obstruct the intestines, sometimes requiring additional surgery.
Shortening of the vagina is a possible complication specific to vaginal hysterectomy. It can cause pain during intercourse.

Such complications are uncommon.

After hysterectomy, women may experience hot flashes, a symptom of menopause, even if they retain their ovaries. However, women who have a hysterectomy are less likely to experience hot flashes than women who have a natural menopause. Surgery may have temporarily blocked blood flow to the ovaries, therefore suppressing estrogen release. If both ovaries have been removed in premenopausal women, the procedure causes premature menopause. Other menopausal symptoms include vaginal dryness and irritation, insomnia, and weight gain.

The most important complications occur in women who have had their ovaries removed. This causes estrogen loss, which places women at risk for osteoporosis (loss of bone density) and a possible increase in risks for heart disease and stroke. A number of drugs are available that can help protect both bones and heart.

Women have typically taken hormone replacement therapy (HRT) after surgery if their ovaries have been removed. HRT can help prevent hot flashes. There have been concerns about HRT-related health risks, including the risk for breast cancer. However, several 2006 studies of postmenopausal women who had hysterectomy indicated that estrogen-only HRT does not increase the risk for breast cancer, except if it is taken for many decades. (Two studies showed no increased risk for breast cancer after 7 years and 15 years, respectively. Women who took estrogen-only HRT for more than 20 years after hysterectomy had only a moderately increased risk.) Combination estrogen-progestin HRT does increase breast cancer risk.

In premenopausal women, such preventive measures are not needed if the ovaries are left intact. The ovaries will usually continue to function and secrete hormones even after the uterus is removed, but the lifespan of the ovaries is reduced by an average of 3 - 5 years. In rare cases, complete ovarian failure occurs right after hysterectomy, presumably because the surgery has permanently cut off the blood supply to the ovaries.

Sexual intercourse may resume 4 - 6 weeks following surgery. The effect of hysterectomy on sexuality is unclear. Studies have reported that up to 25% of women experience increased sexual drive. Nevertheless, some women report no change, and other women develop problems related to sexual function. For example, around 10% of women experience vaginal dryness, about 2% of women develop pain during sex, and another 2% also appear to lose capacity for orgasm.

Two procedures associated with hysterectomy may affect sexuality directly.

Although the clitoris can trigger orgasm even if the cervix is removed, some experts believe that uterine contractions stimulated by sexual intercourse also cause a so-called “deep orgasm.” Retaining the cervix may help to retain this sensation. However, a 2006 review found that women who undergo a total hysterectomy (removal of both uterus and cervix) are no more likely to have sexual difficulties or problems with urinary and bowel function than women who have only their uterus removed.
Patients who have both ovaries removed may be at higher risk for loss of sexuality. Ovaries produce small amounts of testosterone (the male hormone responsible for sexual drive) even after menopause.

Testosterone Replacement. Testosterone replacement therapy may restore sexuality in women who experience a decline in sexual drive. Occasionally, oral or injection treatments can produce male characteristics such as facial hair and voice change. A slow-release pellet inserted every 6 months under the skin in the hip appears to reduce these side effects. Taking hormones long-term almost always carries some risk, and it is not yet known what danger testosterone replacement may pose in women.

Annual Pap smears are recommended for all women with an intact cervix who are 18 years or older or who have become sexually active. After a total hysterectomy, in which the cervix has been removed, a woman does not need annual Pap smears of the cervix. However, she still should get regular pelvic and breast exams. Also, women with a history of abnormal Pap smears usually require annual screening.

Definition

Kegel exercises are a series of pelvic muscle exercises designed to strengthen the muscles of the pelvic floor.

Alternative Names

Pelvic muscle strengthening exercises; Pelvic floor exercises

Information

Dr. Arnold Kegel developed Kegel exercises in 1948 as a method of controlling incontinence in women after childbirth. These exercises are now recommended for:

Women with urinary stress incontinence
Some men who have urinary incontinence after prostate surgery
People who have fecal incontinence

Kegel exercises strengthen the muscles of the pelvic floor to improve urethral and rectal sphincter function. The success of Kegel exercises depends on proper technique and sticking to a regular exercise program.

Some people have trouble finding and isolating the muscles of the pelvic floor. It's important to learn how to tighten (contract) the correct muscles. Most people contract the abdominal or thigh muscles, and don't work the pelvic floor muscles. These incorrect contractions can worsen pelvic floor tone and incontinence.

Several techniques can help you find the right muscles. One approach is to sit on the toilet and start to urinate. Try to stop the flow of urine midstream by tightening your pelvic floor muscles. Repeat this action several times until you learn the feel of contracting the right group of muscles. Do not contract your abdominal, thigh, or buttocks muscles while doing the exercise.

Another approach to help you find the correct muscle group is to insert a finger into the vagina (in women), or rectum (in men). Try to tighten the muscles around your finger as if holding back urine. The abdominal and thigh muscles should stay relaxed.

A woman can also strengthen these muscles by using a vaginal cone, which is a weighted device that is inserted into the vagina. Then try to contract the pelvic floor muscles to hold the device in place.

If you are unsure whether you are doing the Kegel correctly, you can use biofeedback and electrical stimulation to help find the correct muscle group to work.

Biofeedback is a method of positive reinforcement. Electrodes are placed on the abdomen and along the anal area. Some therapists place a sensor in the vagina in women or anus in men, to monitor the contraction of pelvic floor muscles.

A monitor will display a graph showing which muscles are contracting and which are at rest. The therapist can help find the right muscles for performing Kegel exercises.

Electrical stimulation involves using low-voltage electric current to stimulate the correct group of muscles. The current may be delivered using an anal or vaginal probe. The electrical stimulation therapy can be done in the clinic or at home.

Treatment sessions usually last 20 minutes and may be done every 1 - 4 days. Some studies have shown that electrical stimulation might help in treating stress and urge incontinence.

PERFORMING PELVIC FLOOR EXERCISES:

1. Begin by emptying your bladder.

2. Tighten the pelvic floor muscles and hold for a count of 10.

3. Relax the muscle completely for a count of 10.

4. Do 10 exercises, 3 times a day (morning, afternoon, and night).

You can do these exercises at any time and any place. Most people prefer to do the exercises while lying down or sitting in a chair. After 4 - 6 weeks, most people notice some improvement. It may take as long as 3 months to see a major change.

A word of caution: Some people feel that they can speed up the progress by increasing the number of repetitions and the frequency of exercises. However, overexercising can instead cause muscle fatigue and increase urine leakage.

If you feel any discomfort in your abdomen or back while doing these exercises, you are probably doing them wrong. Some people hold their breath or tighten their chest while trying to contract the pelvic floor muscles. Relax and concentrate on contracting just the pelvic floor muscles.

When done the right way, Kegel exercises have been shown very effective for improving urinary continence.

Definition

Stress incontinence is an involuntary loss of urine that occurs during physical activity, such as coughing, sneezing, laughing, or exercise.

Alternative Names

Incontinence - stress

Causes, incidence, and risk factors

The ability to hold urine and control urination depends on the normal function of the lower urinary tract, the kidneys, and the nervous system. You must also have the ability to recognize and respond to the urge to urinate.

Stress incontinence is a bladder storage problem in which the strength of the muscles (urethral sphincter) that help control urination is reduced. The sphincter is not able to prevent urine flow when there is increased pressure from the abdomen.

Stress incontinence may occur as a result of weakened pelvic muscles that support the bladder and urethra or because of a malfunction of the urethral sphincter. The weakness may be caused by:

Brain or nervous system (neurological) injury
Injury to the urethral area
Some medications
Surgery of the prostate or pelvic area

Stress urinary incontinence is the most common type of urinary incontinence in women.

Stress incontinence is often seen in women who have had multiple pregnancies and vaginal childbirths, and whose bladder, urethra, or rectal wall stick out into the vagina (pelvic prolapse).

Risk factors for stress incontinence include:

Being female
Childbirth
Chronic coughing (such as chronic bronchitis and asthma)
Getting older
Obesity
Smoking

Symptoms

Involuntary loss of urine is the main symptom. It may occur when:

Coughing
Sneezing
Standing
Exercising
Engaging in other physical activity

Signs and tests

The health care provider will perform a physical exam, including a:

Genital exam in men
Pelvic exam in women
Rectal exam

In some women, a pelvic examination may reveal that the bladder or urethra is bulging into the vaginal space.

Tests may include:

Inspection of the inside of the bladder (cystoscopy)
Pad test (after placement of a pre-weighed sanitary pad, the patient is asked to exercise -- following exercise, the pad is re-weighed to determine the amount of urine loss)
Pelvic or abdominal ultrasound
Post-void residual (PVR) to measure amount of urine left after urination
Rarely, an electromyogram (EMG) is performed to study muscle activity in the urethra or pelvic floor
Tests to measure pressure and urine flow (urodynamic studies)
Urinalysis or urine culture to rule out urinary tract infection
Urinary stress test (the patient is asked to stand with a full bladder, and then cough)
X-rays with contrast dye of the kidneys and bladder

The health care provider may also measure the change in the angle of the urethra when at rest and when straining (Q-tip test). An angle change of greater than 30 degrees often means there is significant weakness of the muscles and tissues that support the bladder.

Treatment

Treatment depends on how severe the symptoms are and how much they interfere with your everyday life.

The doctor may ask that you stop smoking (if you smoke) and avoid caffeinated beverages (such as soda) and alcohol. You may be asked to keep a urinary diary, recording how many times you urinate during the day and night, and how often urinary leaking occurs.

There are four major categories of treatment for stress incontinence:

Behavioral changes
Medication
Pelvic floor muscle training
Surgery

Behavioral changes involve decreasing how many fluids you drink, if you drink too much during the day. (You should not decrease your fluid intake if you drink normal amounts of fluids.)

Urinating more frequently may help some patients decrease the amount of urine that they leak. Constipation can make urinary incontinence worse, so dietary or medical treatments to help keep regular bowel habits are recommended.

Weight loss has been shown to help decrease symptoms in those who are overweight. Some people with severe stress incontinence may change their activity level to avoid movements such as jumping or running, which can cause greater leakage of urine.

Pelvic muscle training exercises (called Kegel exercises) may help control urine leakage. These exercises improve the strength and function of the urethral sphincter.

Some women may use a device called a vaginal cone along with pelvic exercises. The cone is placed into the vagina, and the woman tries to contract the pelvic floor muscles in an effort to hold it in place. The device may be worn for up to 15 minutes. This procedure should be done two times a day. Within 4 - 6 weeks, most women have some improvement in their symptoms.

Biofeedback and electrical stimulation may be helpful for those who have trouble doing pelvic muscle training exercises. These two methods can help you identify the correct muscle group to work. Biofeedback is a method that helps you learn how to control certain involuntary body responses.

Electrical stimulation therapy uses low-voltage electrical current to stimulate and contract the correct group of muscles. The current is delivered using an anal or vaginal probe. The electrical stimulation therapy may be done at the doctor's office or at home.

Treatment sessions usually last 20 minutes and may be done every 1 - 4 days. Newer techniques are being investigated, including one that uses a specially designed electromagnetic chair that causes the pelvic floor muscles to contract when the patient is seated.

Medicines tend to work better in patients with mild-to-moderate stress incontinence. They include:

Antimuscarinic drugs block bladder contractions. Many doctors prescribe these types of drugs first.
Alpha-adrenergic agonist drugs such as phenylpropanolamine and pseudoephedrine (common ingredients in over-the-counter cold medications) help increase sphincter strength and improve symptoms in many patients.
Imipramine, a tricyclic antidepressant, works in a similar way to alpha-adrenergic drugs.

Estrogen therapy can be used to improve urinary frequency, urgency, and burning in postmenopausal women. It also can improve the tone and blood supply of the urethral sphincter muscles.

However, whether estrogen treatment improves stress incontinence is controversial. Women with a history of breast or uterine cancer should usually not use estrogen therapy for the treatment of stress urinary incontinence.

Surgical treatment is only recommended after the exact cause of the urinary incontinence has been determined. Different types of surgeries are described below.

COLLAGEN INJECTION

A minor surgical procedure called collagen periurethral injection may be recommended for the treatment of male and female stress incontinence caused by urethral sphincter dysfunction. The collagen makes the area around the urethra thicker, which helps control urine leakage.

This procedure is done in an outpatient setting, with a local or spinal anesthesia. The procedure may need to be repeated after a few months to achieve bladder control.

Potential complications include:

Infection
Temporary erectile dysfunction in men
Urine retention

Some people may have a potentially serious allergic reaction to collagen. Any candidate for collagen injection must have an allergy skin test before treatment.

ANTERIOR VAGINAL REPAIR OR PARAVAGINAL REPAIR

These vaginal procedures are often done in women when the bladder is bulging into the vagina. (Such a condition is called a cystocele.) An anterior vaginal repair is done through a surgical cut in the vagina, and a paravaginal repair may be done through a surgical cut in the vagina or abdomen.

In an anterior repair, the supportive tissue between the vagina and bladder is folded and stitched together so the bladder and urethra are in the proper position.

In a paravaginal repair, the supportive tissue between the vagina and bladder is stitched to the tissue covering the pelvic floor muscles, so the bladder and urethra are supported.

Often, these procedures are done along with another procedure for stress incontinence, such as a hysterectomy or retropubic suspension.

NEEDLE BLADDER NECK SUSPENSION

Needle bladder neck procedures use special needles to make a minor cut in the abdomen and vagina. The procedures (Modified Pereyra and Stamey procedure) differ based on the structures that are used to anchor and support the bladder. This type of surgery is only done on women.

Because the success rate tends to be lower than other surgeries, they are not being done as often as they used to be. Possible complications include:

Fistula (rarely)
Inability to urinate
Urge incontinence
Urinary tract infection
Wound infection

RETROPUBIC SUSPENSION

Retropubic suspension is used to describe a group of surgical procedures done to lift the bladder and urethra. These procedures are done through a surgical cut in the abdomen. The procedures (Burch colposuspension and Marshall-Marchetti-Krantz -- MMK) differ based on the structures that are used to anchor and support the bladder.

Possible complications include:

Fistula (rarely)
Inability to urinate
Infection
New urge incontinence
Urinary tract infection

SLING PROCEDURE

Most doctors who treat incontinence recommend a sling operation as the first choice for the treatment of uncomplicated stress incontinence in women. This procedure is rarely done in men.

A sling is formed by taking a piece of the abdominal tissue (fascia) or synthetic material. The man-made sling pushes on the urethral sphincter, preventing leakage of urine during stressful movements.

These procedures require a small surgical cut in the abdomen and vagina. Many different types of the sling procedure have been developed, including a transvaginal tape procedure which uses smaller cuts and can be done as an outpatient surgery.

Possible complications include:

Abnormal connection (fistula) or infection (abscess)
Infection
Urgency
Urge incontinence
Urinary retention
Wearing away of the sling
Vaginal wall that doesn't heal

ARTIFICIAL URINARY SPHINCTER

Artificial urinary sphincter is a surgical device used to treat stress incontinence in men. Artificial urinary sphincters are rarely used in women.

Most health care providers tell their patients to try other treatments first. Possible complications include infection and urethral erosion, which requires that the device be removed. You may need to modify some activities (such as bicycle riding) to accommodate the device.

Expectations (prognosis)

Behavioral changes, pelvic floor exercise therapy, and medication usually improve symptoms rather than cure stress incontinence. Surgery can cure most patients, if they are carefully selected.

Treatment does not work as well in people with:

Conditions that may prevent healing or make surgery more difficult
Other genital or urinary problems
Previous surgical failures

Complications

Complications are rare and usually mild. They can include:

Irritation of the vulva
Pain during intercourse
Unpleasant odors
Vaginal discharge

The condition may affect or disrupt social activities, careers, and relationships.

Calling your health care provider

Call for an appointment with your health care provider if you have symptoms of stress incontinence and they are bothersome.

Prevention

Performing Kegel exercises (tightening the muscles of the pelvic floor as if trying to stop the urine stream) may help prevent symptoms. Doing Kegel exercises during and after pregnancy can decrease the risk of developing stress urinary incontinence after childbirth.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Incontinence is the inability to control the passage of urine. This can range from an occasional leakage of urine, to a complete inability to hold any urine.

The three main types of urinary incontinence are:

Stress incontinence -- occurs during certain activities like coughing, sneezing, laughing, or exercise.
Urge incontinence -- involves a strong, sudden need to urinate followed by instant bladder contraction and involuntary loss of urine. You don't have enough time between when you recognize the need to urinate and when you actually do urinate.
Mixed incontinence -- contains components of both stress and urge incontinence.

Bowel incontinence, a separate topic, is the inability to control the passage of stool.

Alternative Names

Loss of bladder control; Uncontrollable urination; Urination - uncontrollable; Incontinence - urinary

Considerations

Incontinence is most common among the elderly. Women are more likely than men to have urinary incontinence.

Infants and children are not considered incontinent, but merely untrained, up to the time of toilet training. Occasional accidents are not unusual in children up to age 6 years. Young (and sometimes teenage) girls may have slight leakage of urine when laughing.

Nighttime urination in children is normal until the age of 5 or 6.

NORMAL URINATION

The ability to hold urine is dependent on having normal anatomy and a normally functioning urinary tract and nervous system. You must also possess the physical and psychological ability to recognize and appropriately respond to the urge to urinate.

The process of urination involves two phases:

The filling and storage phase
The emptying phase

Normally, during the filling and storage phase, the bladder begins to fill with urine from the kidneys. The bladder stretches to accommodate the increasing amounts of urine.

The first sensation of the urge to urinate occurs when approximately 200 ml (just under 1 cup) of urine is stored. A healthy nervous system will respond to this stretching sensation by alerting you to the urge to urinate, while also allowing the bladder to continue to fill.

The average person can hold approximately 350 to 550 ml (over 2 cups) of urine. The ability to fill and store urine properly requires a functional sphincter (the circular muscles around the opening of the bladder) and a stable, expandable bladder wall muscle (detrusor).

The emptying phase requires the ability of the detrusor muscle to appropriately contract to force urine out of the bladder. At the same time, your body must be able to relax the sphincter to allow the urine to pass out of the body.

Common Causes

Incontinence may be sudden and temporary, or ongoing and long-term. Causes of sudden or temporary incontinence include:

Bedrest -- for example, when recovering from surgery
Certain medications (such as diuretics, antidepressants, tranquilizers, some cough and cold remedies, and antihistamines for allergies)
Increased urine amounts, like with poorly controlled diabetes
Mental confusion
Pregnancy
Prostate infection or inflammation
Stool impaction from severe constipation, causing pressure on the bladder
Urinary tract infection or inflammation
Weight gain

Causes that may be more long-term:

Alzheimer's disease
Bladder cancer
Bladder spasms
Depression
Large prostate in men
Neurological conditions such as multiple sclerosis or stroke
Nerve or muscle damage after pelvic radiation
Pelvic prolapse in women -- falling or sliding of the bladder, urethra, or rectum into the vaginal space, often related to having had multiple pregnancies and deliveries
Problems with the structure of the urinary tract
Spinal injuries
Weakness of the sphincter, the circular muscles of the bladder responsible for opening and closing it; this can happen following prostate surgery in men, or vaginal surgery in women

Home Care

See your doctor for an initial evaluation and to come up with a treatment plan. Treatment options vary, depending on the cause and type of incontinence you have. Fortunately, there are many things you can do to help manage incontinence.

The following methods are used to strengthen the muscles of your pelvic floor:

Bladder retraining -- this involves urinating on a schedule, whether you feel a need to go or not. In between those times, you try to wait to the next scheduled time. At first, you may need to schedule 1 hour intervals. Gradually, you can increase by 1/2 hour intervals until you are only urinating every 3 - 4 hours without leakage.
Kegel exercises -- contract the pelvic floor muscles for 10 seconds, then relax them for 10 seconds. Repeat 10 times. Do these exercises three times per day. You can do Kegel exercises any time, any place.

To find the pelvic muscles when you first start Kegel exercises, stop your urine flow midstream. The muscles needed to do this are your pelvic floor muscles. DO NOT contract your abdominal, thigh, or buttocks muscles. And DO NOT overdo the exercises. This may tire the muscles out and actually worsen incontinence.

Two methods called biofeedback and electrical stimulation can help you learn how to perform Kegel exercises. Biofeedback uses electrodes placed on the pelvic floor muscles, giving you feedback about when they are contracted and when they are not. Electrical stimulation uses low-voltage electric current to stimulate the pelvic floor muscles. It can be done at home or at a clinic for 20 minutes every 1 - 4 days.

Biofeedback and electrical stimulation will no longer be necessary once you have identified the pelvic floor muscles and mastered the exercises on your own.

Vaginal cones enhance the performance of Kegel exercises for women. Other devices for incontinence are also available.

For leakage, wear absorbent pads or undergarments. There are many well-designed products that go completely unnoticed by anyone but you.

Other measures include:

Regulate your bowels to avoid constipation. Try increasing fiber in your diet.
Quit smoking to reduce coughing and bladder irritation. Smoking also increases your risk of bladder cancer.
Avoid alcohol and caffeinated beverages, particularly coffee, which can overstimulate your bladder.
Lose weight if you need to.
Avoid foods and drinks that may irritate your bladder, like spicy foods, carbonated beverages, and citrus fruits and juices.
Keep blood sugar under good control if you have diabetes.

Your doctor may recommend medication or surgery, especially if home care measures are not helping or if your symptoms are getting worse.

Medications that may be prescribed include drugs that relax the bladder, increase bladder muscle tone, or strengthen the sphincter.

Surgery may be required to relieve an obstruction or deformity of the bladder neck and urethra. Uterine or pelvic suspension operations are sometimes needed in women. Men may require prostatectomy (removal of the prostate gland). Incontinence can sometimes be managed by artificial sphincters. These are synthetic cuffs that are surgically placed around the urethra to help retain urine.

If you have overflow incontinence or cannot empty your bladder completely, a catheter may be recommended. But using a catheter exposes you to potential infection.

PREVENTION

Performing Kegel exercises while you are pregnant and soon after delivery may help prevent incontinence related to childbirth.

Call your health care provider if

Discuss incontinence with your doctor. Gynecologists and urologists are the specialists most familiar with this condition. They can evaluate the causes and recommend treatment approaches.

Call your local emergency number (such as 911) or go to an emergency room if any of the following accompany a sudden loss of urine control:

Difficulty talking, walking, or speaking
Sudden weakness, numbness, or tingling in an arm or leg
Loss of vision
Loss of consciousness or confusion
Loss of bowel control

Call your doctor if:

You have been constipated for more than 1 week
You have difficulty starting your urine flow, dribbling, nighttime urination, pain or burning with urination, increased frequency or urgency, or cloudy or bloody urine
You are taking medications that may be causing incontinence -- DO NOT adjust or stop any medications without talking to your doctor
You are over 60 years old and your incontinence is new, especially if you are also having trouble with your memory or caring for yourself
You have the urge to go often, but are only passing small amounts of urine
Your bladder feels full even after you have just urinated
Incontinence persists for more than 2 weeks even with exercises to strengthen your pelvic muscles

What to expect at your health care provider's office

Your doctor will take your medical history and perform a physical examination, with a focus on your abdomen, genitals, pelvis, rectum, and neurologic system.

Medical history questions may include:

How long has incontinence been a problem for you?
How many times does this happen each day?
Are you aware of the need to urinate before you leak?
Are you immediately aware that you have passed urine?
Are you wet most of the day?
Do you wear protective garments in case of accidents? How often?
Do you avoid social situations in case of accidents?
Have you had urinary tract infections in the past? Do you think that you may have one now?
Is it more difficult to control your urine when you cough, sneeze, strain, or laugh?
Is it more difficult to control your urine when running, jumping, or walking?
Is your incontinence worse when sitting up or standing?
Are you constipated? For how long?
Is there anything you do to reduce or prevent accidents?
Have you ever been treated for this condition before? Did it help?
Have you tried pelvic floor exercises (Kegel)? Do they help?
What procedures, surgeries, or injuries have you had?
What medications do you take?
Do you drink coffee? How much?
Do you drink alcohol? How much?
Do you smoke? How much each day?
Do you have diabetes or a family history of diabetes?
Do you have any other symptoms?

Diagnostic tests that may be performed include:

Urinalysis
Urine culture to check for infection if indicated
Cystoscopy (inspection of the inside of the bladder)
Urodynamic studies (tests to measure pressure and urine flow)
Uroflow (to measure pattern of urine flow)
Post void residual (PVR) to measure amount of urine left after urination

Other tests may be performed to rule out pelvic weakness as the cause of the incontinence. One such test is called the Q-tip test. This test involves measurement of the change in the angle of the urethra when it is at rest and when it is straining. An angle change of greater than 30 degrees often indicates significant weakness of the muscles and tendons that support the bladder.

Highlights

Uterine Artery Embolization Versus Standard Surgery

Many women with fibroids are considering a procedure called uterine artery embolization (UAE) as an alternative to standard surgery such as hysterectomy or myomectomy. A study published in 2007 in the New England Journal of Medicine compared these treatment approaches. The study suggested that UAE results in shorter hospital stay and faster recovery time, but a small percentage of women may later need repeat embolization or a hysterectomy. There were similar improvements in quality of life regardless of whether a woman had UAE or standard surgery.

Magnetic-Resonance Guided Focused Ultrasound (MRgFUS)

MRgFUS is a new non-surgical approach for treating fibroids. A 2006 study in Obstetrics and Gynecology indicated that taking gonadotropin-releasing hormone (GnRH) agonist drugs before this procedure may help reduce fibroid volume and improve outcomes.

Predictors of Hysterectomy

Combined factors can predict whether a woman will decide to have a hysterectomy, according to a 2007 study published in the Journal of the American College of Surgeons. Women who met all three criteria had a 95% chance of having a hysterectomy:

Presence of symptoms (pelvic pain, bleeding, symptomatic fibroids)
Lack of symptom improvement despite treatment
Previous use of GnRH agonist drugs

Hysterectomy and Sexual Function

Hormone Replacement Therapy (HRT) and Breast Cancer Risk

Estrogen-only HRT after hysterectomy does not appear to increase breast cancer risk when used in the short term (up to 20 years), according to several 2006 studies. Combination estrogen-progestin HRT does increase breast cancer risk.

Introduction

A uterine fibroid (known medically as a leiomyoma or myoma ) is a noncancerous (benign) growth composed of smooth muscle and connective tissue. The size of a fibroid varies from that of a pinhead to larger than a melon. Fibroids have been reported weighing more than 20 pounds.

Fibroids originate from the thick wall of the uterus and are categorized by the direction in which they grow:

Intramural fibroids grow within the middle and thickest layer of the uterus (called the myometrium). They are the most common fibroids.
Subserosal fibroids grow out from the thin outer fibrous layer of the uterus (called the serosa). Subserosal can be either stalk-like (pedunculated) or broad-based (sessile). These are the second most common fibroids.
Submucous fibroids grow from the uterine wall toward and into the inner lining of the uterus (the endometrium). Submucous fibroids can also be stalk-like or broad-based. Only about 5% of fibroids are submucous.

Fibroid tumors may not need to be removed if they are not causing pain, bleeding excessively, or growing rapidly.

The Primary Organs and Structures in the Reproductive System. The primary structures in the reproductive system are as follows:

The uterus is a pear-shaped organ located between the bladder and lower intestine. It consists of two parts, the body and the cervix.
When a woman is not pregnant the body of the uterus is about the size of a fist, with its walls collapsed and flattened against each other. During pregnancy the walls of the uterus are pushed apart as the fetus grows.
The cervix is the lower portion of the uterus. It has a canal opening into the vagina with an opening called the os, which allows menstrual blood to flow out of the uterus into the vagina.
Leading off each side of the body of the uterus are two tubes known as the fallopian tubes. Near the end of each tube is an ovary.
Ovaries are egg-producing organs that hold 200,000 - 400,000 follicles (from folliculus, meaning "sack" in Latin). These cellular sacks contain the materials needed to produce ripened eggs, or ova.

The inner lining of the uterus is called the endometrium. During pregnancy this inner lining thickens and becomes enriched with blood vessels to house and support the growing fetus. If pregnancy does not occur, the endometrium is shed as part of the menstrual flow. Menstrual flow also consists of blood and mucus from the cervix and vagina.

In women, six key hormones serve as chemical messengers that regulate the reproductive system:

The hypothalamus first releases the gonadotropin-releasing hormone (GnRH).
This chemical, in turn, stimulates the pituitary gland to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
Estrogen, progesterone, and the male hormone testosterone are secreted by the ovaries at the command of FSH and LH and complete the hormonal group necessary for reproductive health.

Causes

Inherited genetic factors may be important in many cases of fibroids. Researchers are investigating unique genetic factors that regulate hormones. Proteins called growth factors may be responsible for some of the abnormalities leading to uterine muscle overgrowth and fibroids. Scientists have identified chromosomes carrying a total of 145 genes that may affect fibroid growth. Some experts report that uterine fibroids are inherited from paternal (the father's) genes.

Uterine fibroids often grow during pregnancy, and they degenerate after menopause. From these observations and certain studies researchers are fairly certain that the female hormones, both estrogen and progesterone, play a role in their growth. Their role, however, is not clear. Some theories about the relationship to fibroids and estrogen include the following:

Estrogen patterns in fibroids are similar to those in pregnancy. That is, like smooth muscle cells in the uterus during pregnancy, fibroid cells exposed to female hormones do not respond normally to signals that would make them self-destruct and return to a nonpregnant state. (This natural self-destruction is a process called apoptosis). Instead, they continue to grow.
Some evidence suggests that estrogen may inhibit a tumor-suppressor gene called p53 in fibroid tissue, therefore triggering cell proliferation leading to fibroid growth. (P53 plays a role in some cancer-cell growth, although in this case the process is not cancerous.)

The formation of fibroids may be attributable to abnormalities in substances called growth factors. These are special proteins, secreted by different cell types, that are responsible for cell-to-cell interaction. Many of these substances regulate a process called angiogenesis, which causes new blood vessels to sprout from pre-existing ones. The production of new blood vessels then feeds any existing growth, such as fibroids.

The growth factors that appear to play an important role in many female reproductive disorders are Basic Fibroblast Growth Factor (BFGF) and Vascular Endothelial Growth Factor (VEGF). BFGFs are involved in the proliferation of cells that form connective tissue, which supports the body's organs and structure. VEGFs are involved with cell growth in smooth muscles that line blood vessels. Some evidence suggests they play a role in uterine fibroids.

Other growth factors being studied specifically for fibroids include Insulin-like Growth Factor (IGF)-I, Epidermal Growth Factor (EGF), Platelet Derived Growth Factor (PDGF), and Transforming Growth Factor (TGF).

Symptoms

Fewer than 25% of patients with fibroids experience symptoms. When they do, they include:

The most common symptom is prolonged and heavy bleeding during menstruation. This is caused by fibroid growth bordering the uterine cavity. In severe cases, heavy bleeding may last as many as 2 weeks. Fibroids rarely bleed between periods, except in a few cases of very large fibroids.
Large fibroids can also cause pressure and pain in the abdomen or lower back that sometimes feels like menstrual cramps.
As the fibroids grow larger, some women feel them as hard lumps in the lower abdomen.
Very large fibroids may give the abdomen the appearance of pregnancy and cause a feeling of heaviness and pressure. In fact, large fibroids are defined by comparing the size of the uterus to the size it would be at specific months during gestation.
Unusually large fibroids may press against the bladder and urinary tract and cause frequent urination or the urge to urinate, particularly during the night when a woman is lying down.
Abnormal pain during intercourse (called dyspareunia).
If the fibroids press on the ureters (the tubes going from the kidneys to the bladder), obstruction or blockage of urine may result.
Fibroid pressure against the rectum can cause constipation.

Risk Factors

Uterine fibroids are the most common tumor found in female reproductive organs. It is estimated that over 50% of women age 30 - 50 have fibroids, although they cause symptoms in only about 25%. A survey of 1,364 women suggested an even higher prevalence of over 80% in African-American women and almost 70% in white women. A number of possible risk factors have been identified, but very little research exists to confirm them.

Uterine fibroids are particularly common in African-American women, with an estimated prevalence of 50 - 75%. These women are also more likely to have severe pain, anemia, and larger and more numerous fibroids than women in other population groups. Although genetics may play a role, women of African descent who live in other countries do not appear to have as high an incidence of fibroids. This suggests that diet or other environmental factors are at work in the development of fibroids in African-American women.

Fibroids can start to grow soon after puberty, although usually they are detected when a woman reaches young adulthood. Women with fibroids are at risk for accelerated fibroid growth when estrogen levels are high or when lifestyle behaviors keep estrogen levels high.

Some examples of risk factors for fibroids that are also associated with high estrogen exposure include:

Early onset of menstrual period (before age 12)
Being overweight and sedentary
Never being pregnant. The risk for fibroids decreases with more children. (This risk factor, however, may be due to a greater risk for infertility caused by fibroids in the first place.)

Combined Oral Contraceptives. Combined oral contraceptives contain estrogen and progesterone and the evidence on their effects on fibroids have been conflicting. Early reports suggested they might be a risk factor. Most studies conducted more recently, however, have found no association and some even suggest that the newer low-dose OC combinations may be protective.

Hormone Replacement Therapy. Hormone replacement therapies (HRT) contain estrogen alone or estrogen plus progesterone. After menopause, fibroids usually shrink. Researchers are investigating whether the hormones used in HRT could cause existing fibroids to persist or even grow. Some studies, but not all, have found greater fibroid growth with the use of patch-administered hormone drugs. (In one of the studies, taking oral estrogen, however, had no effect.) A 2001 systematic review of studies reported some fibroid growth in women taking HRT, but usually without any significant symptoms.

If HRT has an effect on fibroid growth, it is unlikely to be severe. Any increase in fibroid growth during menopause must be evaluated surgically by a gynecologist since such growth, even if a woman is on hormone replacement therapy, may mean cancer.

High blood pressure (hypertension) may be associated with increased fibroid risk according to a 2005 epidemiologic study. The prospective study tracked women in the Nurses’ Health Study for 10 years and found that for every 10 mm/Hg increase in diastolic blood pressure, the risk for developing fibroids increased by 8 - 10%. (Interestingly, women who used antihypertensive medications had the highest risk.). Researchers reported that women with hypertension were 24% more likely to develop fibroids and that the longer a woman had hypertension, the greater her risk.

Complications

Effect on Fertility. The effect of fibroids on fertility is controversial. A 2002 analysis suggested that they may account for infertility in only 1 - 2.4% of women who have trouble conceiving. Large fibroids may cause infertility by:

Impairing the uterine lining
Blocking the fallopian tubes
Distorting the shape of the uterine cavity
Altering the position of the cervix and preventing sperm from reaching the uterus

Some evidence suggests that even small fibroids may reduce the chances of pregnancy in women who are undergoing assisted reproductive techniques. Treatments to reduce fibroids may be helpful in such women, although there has been little research on this subject.

Effect on Pregnancy.Fibroids can increase pregnancy complications and delivery risks. These include:

Cesarean section delivery
Breech presentation (baby enters the birth canal upside down with feet or buttocks emerging first)
Preterm birth
Placenta previa (placenta covers the cervix)
Excessive bleeding after giving birth (postpartum hemorrhage)

A 2006 study found that pregnant women with at least one fibroid had the following increased risks: cesarean delivery (57%), breech birth (64%), preterm delivery (45%), placenta previa (86%), and postpartum hemorrhage (157%).

Anemia due to iron deficiency can develop if fibroids cause excessive bleeding. Oddly enough, smaller fibroids, usually submucous, are more likely to cause abnormally heavy bleeding than larger ones.

Most cases of anemia are mild. Mild anemia can cause weakness and fatigue. Moderate-to-severe anemia can cause shortness of breath, rapid heart rate, lightheadedness, headaches, ringing in the ears (tinnitus), irritability, pale skin, restless legs syndrome, and mental confusion. Heart problems can occur if prolonged and severe anemia is not treated. Pregnant women who are anemic, particularly in the first trimester, have an increased risk for a poor pregnancy outcome.

Large fibroids that press against the bladder occasionally result in urinary tract infections. Pressure on the ureters may cause urinary obstruction and kidney damage.

The female and male urinary tracts are relatively the same except for the length of the urethra.

Fibroids can cause cramping during a period, which can be quite intense at times.

Pain can also develop if the blood supply is cut off from the fibroid tissue. In such cases, the cells blacken and die (a process called necrosis) from lack of oxygen. This event may occur under the following circumstances:

A very large fibroid outgrows its own blood supply.
A pedunculated fibroid (one that grows on a stem from the uterine wall) becomes twisted, thus cutting off its blood supply.
Pregnancy occurs, in which the risk for fibroid cell degeneration and necrosis increases.

Rarely, a fibroid breaks away from the uterus and develops in other locations. They are typically one of the following:

Benign Metastasizing Leiomyoma or BML (which usually spreads to the lung)
Disseminated Peritoneal Leiomyomatosis (which spreads to the abdominal wall)

Neither is cancerous, although there is some evidence that BML, which often occurs after menopause, may represent a slow-growing variant of leiomyosarcoma.

Fibroids are nearly always noncancerous, even if they have abnormal cell shapes. Cancer of the uterus nearly always develops in the lining of the uterus (endometrial cancer). Only in rare cases (less than 0.1%) does cancer develop from a malignant change in a fibroid (called leiomyosarcoma). Nevertheless, rapidly enlarging fibroids in a premenopausal woman or even slowly enlarging fibroids in a postmenopausal woman require surgical evaluation to rule out cancer.

Diagnosis

A doctor will perform a pelvic examination to check for pregnancy-related conditions and signs of fibroids or other abnormalities, such as ovarian cysts.

The doctor needs to have a complete history of any medical or personal conditions that might be causing heavy bleeding:

Any family history of menstrual problems or bleeding disorders.
The presence or history of any medical conditions that might be causing heavy bleeding. Women who visit their gynecologist with menstrual complaints, particularly heavy bleeding, pelvic pain, or both may actually have an underlying medical disorder, which must be ruled out.
The pattern of the menstrual bleeding. (If it occurs during regular menstruation, nonhormonal treatments are tried first. If bleeding is irregular, occurs between periods, with premenstrual pain, after sex, or is associated with pelvic pain, the doctor should look for specific conditions that may cause these problems.)
Regular use of any medications (including vitamins and over-the-counter drugs).
Diet history, including caffeine and alcohol intake.
Past or present contraceptive use.
Any recent stressful events.
Sexual history. (It is very important that the patient trust the doctor enough to describe any sexual activity that might be risky.)

Almost all women, at some time in their reproductive life, experience heavy bleeding during menstrual periods ( menorrhagia ). Being taller, older, and having a higher number of pregnancies increase the chances for heavier-than-average bleeding. In some cases the cause of heavy bleeding is unknown, but a number of conditions can cause menorrhagia or contribute to the risk:

Miscarriage. An isolated instance of heavy bleeding usually after the period due date may be due to a miscarriage. If the bleeding occurs at the usual time of menstruation, however, miscarriage is less likely to be a cause.
Having late periods or approaching menopause. These events may cause occasional menorrhagia.
Uterine polyps. (These are small benign growths in the uterus.)
Certain contraceptives. (Oral contraceptives or an intrauterine device, an IUD.)

The intrauterine device (IUD) shown uses copper as the active contraceptive; others use progesterone in a plastic device. IUDs are very effective at preventing pregnancy (less than 2% chance per year for the progesterone IUD, less than 1% chance per year for the copper IUD). IUDs come with an increased risk of ectopic pregnancy and perforation of the uterus, and do not protect against sexually transmitted disease. IUDs are prescribed and placed in the uterus by a health care provider.

Bleeding disorders. Bleeding disorders that impair blood clotting can cause heavy menstrual bleeding and, according to different studies, have been associated with between 10 - 17% of menorrhagia cases. Von Willebrand disease, a genetic condition, is the most common of these bleeding disorders. Most, but not all, studies report this problem to be more common in African-American than Caucasian women. Most bleeding disorders have a genetic basis and should be suspected in adolescent girls who experience heavy bleeding.
Uterine cancer.
Pelvic infections.
Endometriosis. (These are small implants of uterine tissue. They are more likely to cause pain than bleeding.)

Adenomyosis. This condition occurs when glands from the uterine lining become embedded in the uterine muscle. Its symptoms are nearly identical to fibroids (heavy bleeding and pain), and in one study fibroids were also present in 62% of cases. It is most likely to develop in middle-aged women who have had many children.
A number of medical conditions, including thyroid problems, systemic lupus erythematosus, diabetes, certain cancers and chemotherapies, and some uncommon blood disorder.
Certain drugs, including anticoagulants and anti-inflammatory medications.
In many cases, the cause of heavy bleeding is unknown.

Hysteroscopy is a procedure that may be used to detect the presence of fibroids, polyps, or other causes of bleeding. Although less invasive procedures can also detect causes of abnormal uterine bleeding, hysteroscopy has the added advantage of serving as a surgical procedure for the removal of submucous fibroids. It is also quite useful in ruling out cancer. If cancer is suspected, more invasive procedures, such as dilation and curettage (D&C) or endometrial biopsy, are warranted.

Hysteroscopy is non-invasive; however, 30% of women report severe pain with the procedure. The use of an anesthetic spray, such as lidocaine, may be highly effective in preventing pain during this procedure. Other complications include excessive fluid absorption, infection, and uterine perforation.

Ultrasound and Sonohysterography. Ultrasound is the standard imaging technique for evaluating the uterus and ovaries, detecting fibroids, ovarian cysts and tumors, and also obstructions in the urinary tract. It uses sound waves to produce an image of the organs and entails no risk and very little discomfort.

Transvaginal sonohysterography uses ultrasound along with saline infused into the uterus, which enhances the visualization of the uterus. This technique is proving to be more accurate than standard ultrasound in identifying potential problems. Some experts believe it should be the first-line tool for diagnosing heavy bleeding.

Magnetic Resonance Imaging. Magnetic resonance imaging (MRI) provides a better image of any fibroids that might be causing bleeding. An MRI can help the doctor decide if a woman is a candidate for minimally invasive uterine artery embolization (UAE). Fibroids with low blood flow (“nonviable tumors”) may not be suitable for UAE. An MRI may also be better than an ultrasound for evaluating uterine size and fibroid location.

When heavy or abnormal bleeding occurs, an endometrial (uterine) biopsy can be performed in the office along with an ultrasound. It is usually used with a procedure called dilation and curettage (D&C), which is particularly important to rule out uterine (endometrial) cancer. A D&C is a somewhat invasive procedure:

A D&C is usually done in an outpatient setting so that the patient can return home the same day, but it sometimes requires a general anesthetic. It may need to be performed in the operating room to rule out serious conditions or treat some minor ones that may be causing the bleeding.
The cervix (the neck of the uterus) is dilated (opened).
The surgeon scrapes the inside lining of the uterus and cervix.

Click the icon to see an image of a D&C.

The procedure is used to take samples of the tissue and to relieve heavy bleeding in some instances. D&C can also be effective in scraping off small endometrial polyps, but it is not very useful for most fibroids, which tend to be larger and more firmly attached.

Lifestyle Changes

Because fibroids are almost never life-threatening, watchful waiting is a reasonable option for many women (even those with large fibroids), particularly if they are approaching menopause.

Any woman who chooses watchful waiting should be sure other causes of heavy bleeding have been ruled out. She should also have regular pelvic examinations and ultrasounds performed to monitor the growth of the fibroid.

Foods for Maintaining Healthy Iron Stores. The following are some suggestions for increasing iron levels in the diet:

The best foods for increasing or maintaining healthy iron levels contain absorbable iron, called heme iron. Such foods include (in order of iron-richness) clams, oysters, organ meats, beef, pork, poultry, and fish.
About 60% of iron in meat is poorly absorbed; this is a form called non-heme iron. Eggs, dairy products, and vegetables that contain iron only have the non-heme form. Such plants include dried beans and peas, iron-fortified cereals, bread, and pasta products, dark green leafy vegetables (chard, spinach, mustard greens, kale), dried fruits, nuts, and seeds.
Increasing intake of vitamin-C rich foods can enhance absorption of non-heme iron during a single meal, although regular intake of vitamin C does not appear to have any significant effect on iron stores. In any case, vitamin-C rich foods are healthy and include broccoli, cabbage, citrus fruits, melon, tomatoes, and strawberries. One orange or 6 ounces of orange juice can double the amount of iron your body absorbs from plant foods.

Like most vitamins, vitamin C may be obtained in the recommended amount with a well-balanced diet, including some enriched or fortified foods.

Foods containing riboflavin (vitamin B2) may help enhance the response of hemoglobin to iron. Sources include liver, dried fortified cereals, and yogurt.
Cooking in cast iron pans and skillets is known to increase iron content of food. According to one study, however, boiling, steaming, or stir-frying many vegetables in utensils composed of any material significantly increases the release of iron stored in plants so it is available to the body.
Certain nutrients, such as tannin (found in tea) or phytic acid (found in foods such as seeds and bran) interfere with the body's absorption of dietary iron. (It is commonly believed that fiber impedes iron absorption, but researchers report that it most likely has no effect.)

Sources of Vitamins B12 and Folate. Vitamins B12 and folate are important for prevention of anemia related to nutritional deficiencies. Although this anemia is not necessarily related to fibroids, these vitamins are very important for good health in general and for reproductive health in women.

The only natural dietary sources of B12 are animal products such as meats, dairy products, eggs, and fish (clams and oily fish are very high in B12). Like other B vitamins, B12 is added to commercial dried cereals. The recommended daily allowance (RDA) is 2.4 mcg a day. Deficiencies are rare in young people, although the elderly may have trouble absorbing natural vitamin B12 and require synthetic forms from supplements and fortified foods.

Folate is best found in avocado, bananas, orange juice, cold cereal, asparagus, fruits, green, leafy vegetables, dried beans and peas, and yeast. The synthetic form, folic acid, is added to commercial grain products. Vitamins are usually made from folic acid, which is about twice as strong as folate. Many experts recommend that adults have 400 mcg of folic acid daily, which is considerably higher than standard recommendations of 400 mcg of folate. Low levels of folate during pregnancy are common without supplements; deficiencies at that time increase the risk of neural tube defects in newborns. Women who are planning to get pregnant should take 400 mcg of folic acid before conception as well as when they are pregnant or breast feeding.

Iron Supplements. Iron supplements are best for restoring iron levels, but they should be used only when dietary measures have failed. Women should always discuss such supplements with their doctor.

See In-Depth Report #57: Anemia.]

Many women with menstrual disorders may resort to alternative treatments. There has been little research on whether any such therapies benefit fibroids.

Acupuncture. Some women report relief from pelvic pain and heaviness after acupuncture

Click the icon to see an image of acupuncture.

Yoga. Yoga exercises help some women relieve sensations of heaviness and pressure.

Herbal Remedies. Herbal remedies used for fibroids include ginseng or herbal combinations of rhubarb, cinnamon, and sargassum seaweed. There is no scientific evidence that these herbs are effective. Pycnogenol is a plant extract from the bark of the French maritime tree. Studies suggest it may provide some relief for menstrual pain (dysmenorrhea).

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Patients should check with their doctor before using any herbal remedies or dietary supplements.

Medications

Because fibroid growth tends to stop and regress after menopause, the important reproductive hormones -- estrogen, progesterone, or both -- most likely play a critical role in their survival. Some drugs that block either of these hormones are used to treat severe fibroids with some success.

Oral contraceptives (OCs) are sometimes used to control the heavy menstrual bleeding (menorrhagia) associated with fibroids, but they do not help prevent fibroid growth. Newer types of continuous-dosing OCs, such as Seasonique, reduce the number of periods a woman has per year. In May 2007, the FDA approved Lybrel, a continuous-dosing OC that completely eliminates periods.

Intrauterine devices (IUDs) that release progestin can be very beneficial for menorrhagia. Specifically, the levonorgestrel-releasing intrauterine system, or LNG-IUS (Mirena, FibroPlant), has shown excellent results. Many experts now recommend the LNG-IUS as a first-line treatment for menorrhagia, particularly for women who may face hysterectomy (removal of uterus), conservative surgery such as endometrial resection (removal of endometrial lining), or endometrial ablation (destruction of endometrial lining). [See In-Depth Report #100: Menstrual disorders.]

Gonadotropin releasing hormone (GnRH) blocks the release of the reproductive hormones LH (luteinizing hormone) and FSH (follicular-stimulating hormone). As a result, the ovaries stop ovulating and no longer produce estrogen. GnRH agonists include goserelin (Zoladex), buserelin, a monthly injection of leuprolide (depot Lupron), and nafarelin (Synarel), a nasal spray. Such drugs may be used alone or in preparation for procedures used to destroy the uterine lining.

These drugs may be used in the following situations:

As preoperative treatment 3 - 4 months before uterine surgery. In a major analysis, the use of GnRH agonists reduced fibroid size and uterus volume, helped correct any existing anemia due to blood loss, reduced blood loss during surgery, and reduced the duration of hospital stay. (Some experts question, however, whether the benefits outweigh the costs.)
For women with fibroids nearing menopause. (Such women only need them for a short period.)
Possibly helpful in improving subsequent fertility. (However, women should not try to become pregnant while taking these drugs, as they pose a risk for birth defects.)

While GnRH agonists can reduce fibroids by between 30 - 90% of original size, they have certain limitations:

They are not permanent cures, and fibroids regrow after the drugs are discontinued.
They are injected drugs and cannot be taken orally.
They are expensive.
Long-term use of GnRh agonists causes bone density loss, which can lead to osteoporosis.

Before using these drugs, the doctor should be certain that no other complicating conditions are present, particularly leiomyosarcoma (cancer). The use of these drugs can delay treatment of the malignancy and cause severe complications.

Commonly reported side effects, which can be severe in some women, include menopausal-like symptoms. These symptoms include hot flashes, night sweats, changes in the vagina, weight change, and depression. The side effects vary in intensity, depending on the GnRH agonist. They may be more intense with leuprolide and persist after the drug has been stopped.

The most important concern is possible osteoporosis from estrogen loss. Women should not take these drugs for more than 6 months. Certain approaches may preserve enough estrogen to protect bones and still effectively relieve endometriosis symptoms:

Add-back therapy, which provides doses of estrogen and progestin that are high enough to maintain bone density but too low to offset the beneficial effects of the GnRH agonist.
Intermittent leuprolide, which uses repeated 6-month courses of GnRH agonists followed by an average of 9 months of symptom control only.
Taking GnRH agonists in very low doses is an alternate approach, but is still largely untested.
Adding a bone-protective drug may be helpful. The standard ones are bisphosphonates, which include alendronate (Fosamax), risedronate (Actonel), and etidronate (Didronel). Other drugs are being tested in combination with a GnRH agonist to preserve bone. They include the parathyroid hormone teriparatide (Forteo) and selective estrogen-receptor modulators (SERMs), such as raloxifene (Evista).

Danazol (Danocrine) resembles a male hormone. It suppresses estrogen and is effective for heavy menstrual bleeding caused by fibroids. In some women it produces male characteristics, such as facial hair and voice change. Other side effects include weight gain, acne, and dandruff. It may increase the risk for unhealthy cholesterol levels. A few cases of blood clots and strokes have been reported. There is no available long-term experience using danazol for fibroids.

Gestrinone. Antiprogestins are promising drugs for fibroids. Gestrinone has been shown to reduce uterine volume and stop bleeding. In addition, benefits appear to persist. In one study, 89% of the women maintained smaller uterine volume for at least 18 months after stopping the treatment. In another study, bone density even increased slightly. Adverse effects of gestrinone include male hormone symptoms, such as acne, and possibly the development of unhealthy cholesterol levels.

Mifepristone. Mifepristone (Mifeprex) is an anti-progestin that has reduced fibroid size in some studies. In one study, it reduced fibroids as significantly as GnRH agonists, and the fibroids were less likely to recur. However, this medicine can have severe side effects.

Asoprisnil. A promising new antiprogestin called Asoprisnil has been shown to reduce fibroids. The drug is in late-stage clinical trials.

Although they have not been studied for fibroids, nonsteroidal anti-inflammatory drugs (NSAIDs) taken on a regular schedule reduce heavy menstrual bleeding and pain from unknown causes. These drugs reduce inflammation, in part by their action against prostaglandins, the chemicals that stimulate uterine contractions and cause pain. Aspirin is the most common NSAID, but there are dozens of others, including ibuprofen (Advil, Motrin) and naproxen (Aleve, Anaprox, Naprosyn). Both ibuprofen and naproxen are recommended for menstrual pain. However, long-term use of any NSAID can increase the risk for gastrointestinal bleeding and ulcers. In addition, long-term use of high-dose NSAIDs (with the exception of aspirin) can increase the risk for heart attacks and strokes. To reduce these risks, it is best to take the lowest dose of NSAIDs for the shortest time possible.

A number of other drugs are under investigation for treating fibroids:

Selective estrogen-receptor modulators (SERMs) are drugs that have some of the effects of estrogen but do not produce some of its complications, such as a higher risk for uterine cancer. Raloxifene (Evista) is proving to help prevent bone loss in patients taking GnRH agonists for uterine fibroids, and may also be helpful as a single drug for preventing fibroid growth.
Drugs that block growth factors believed to play a role in fibroids are also under investigation. Pirfenidone is one such drug, which blocks fibroid cell reproduction. Another is interferon alpha, substance that inhibits angiogenesis (the growth of new blood vessels).
Drugs derived from retinoids (vitamin A compounds) may inhibit cell proliferation in fibroid tissue.
Fulvestrant (Faslodex) blocks estrogen and has been studied for uterine fibroids and endometriosis, although progress in these areas has stalled in favor of research for its use in breast cancer.

Surgery

If nonsurgical strategies do not relieve symptoms, surgery may be the best option for treatment. Surgery may be indicated depending on a number of factors:

Intractable Side Effects. Surgery may be warranted if fibroids are causing distressing and intractable symptoms that have not been relieved by nonsurgical or minimally invasive therapies. Assuming, however, that symptoms do not pose serious health or life-threatening conditions, a woman should make her decision based on the factors she deems important (the desire for children, for example).

Ureteral Obstruction. Large fibroids sometimes press down on the ureters (the tubes going from each kidney to the bladder), thereby blocking urine from emptying into the bladder. Because ureteral obstructions can permanently damage kidneys, surgery may be indicated.

Inability to Evaluate Ovaries. The risk for missing a diagnosis of ovarian cancer is higher when fibroids are too large to permit evaluation of the ovaries by pelvic examination or ultrasound. Ovarian cancer is particularly deadly because it is so difficult to catch early enough for curative treatment. The risk for this cancer, however, is very low in women without a family history, especially before menopause. Women with a family history of ovarian cancer and large fibroids may need to consider surgery.

Enlarging Fibroids. Rapidly growing fibroids may signify cancer (leiomyosarcoma), which must be ruled out. In postmenopausal women, even slow growth raises suspicions for cancer. However, many hysterectomies have been inappropriately performed because of large noncancerous fibroids that were only suspected to be cancerous. Women should be sure that diagnostic procedures have been as thorough as possible if they want to avoid an unnecessary hysterectomy.

Severe Anemia from Heavy Bleeding. When iron supplementation, resection (surgical removal) of submucous fibroids by hysteroscopy, or GnRH agonist therapy fails to resolve anemia and bleeding, major surgery (myomectomy or hysterectomy) may be recommended.

Hysterectomy. Until recently, hysterectomy was the only surgical option for uterine fibroids. This procedure involves the surgical removal of the uterus and is often accompanied by oophorectomy (the removal of the ovaries). With this procedure, fertility is not preserved. Other options may be available for many women, even those who have large fibroids. Discuss all possibilities with your physician.
Myomectomy. Myomectomy is the surgical removal of only one or more fibroids. Myomectomy usually involves a laparotomy (a procedure that uses a wide abdominal incision) or less invasive surgical techniques, such as laparoscopy and hysteroscopy. In such cases, unlike with hysterectomy, this technique may preserve fertility.
Uterine Artery Embolization (UAE). UAE, also called uterine fibroid embolization (UFE), is a non-surgical radiology procedure. An interventional radiologist injects small plastic particles through a catheter placed in the uterine artery. The particles block the blood supply to the fibroids and cause them to shrink
Other Procedures. Endometrial ablation (destruction of the lining of the uterus) may be useful in women with small fibroids and heavy bleeding. Myolysis is another procedure best suited for women with specific types of small fibroids. Magnetic resonance-guided focused ultrasound (MRgFUS) is the newest type of fibroid procedure. Myolysis and MRgFUS use heat to cut off the blood supply to fibroids.

Women should discuss each option with their doctor. Deciding on the surgical procedure depends on the location, size, and number of fibroids. Certain procedures affect a women’s fertility and are recommended only for women who are past childbearing age or who do not want to become pregnant. The risk for bleeding increases with the surgeon's inexperience, so patients are urged to investigate the surgeon's track record.

A study published in 2007 in the New England Journal of Medicine compared outcomes for uterine artery embolization (UAE) versus standard surgery (hysterectomy or myomectomy). Researchers found that after 1 year, women experienced similar improvements in quality of life regardless of the procedure. Women who had UAE had shorter hospitalizations and faster recovery than those who had standard surgery. However, around 10% of women who had UAE required a repeat procedure (embolization or hysterectomy) during the first year, and another 10% required additional treatment after the first year.

Other Procedures

In order to operate on the uterus, the surgeon may choose to reach the area through a wide abdominal incision (laparotomy) or use less invasive measures with the use of endoscopy. The decision is usually based on the severity of the case. Women should discuss all options very carefully and be sure that their surgeons have had experience with any procedure they choose.

Laparotomy. Laparotomy is the standard abdominal surgical procedure. It is invasive and usually requires a wide abdominal horizontal incision right above the pubic bone, the so-called bikini incision.

Endoscopy. Endoscopic techniques used for uterine disorders are hysteroscopy and laparoscopy. Endoscopic techniques are used increasingly to replace conventional surgical techniques for many disorders. A common factor in all endoscopic procedures is the use of a fiberoptic scope and tubes, tiny camera lenses, and minuscule surgical instruments. Any incisions made are very small, Band-Aid size.

Operative Hysteroscopy. In this procedure, the cervix is dilated, which requires either a local or general anesthetic. A device called a hysteroscopy is inserted up through the vagina and cervix into the uterine cavity. It contains tiny surgical instruments as well as a mini-camera and light source to view images of the uterus, which are transmitted to a video monitor. This approach is becoming increasingly common. Complication rates include excessive fluid absorption, infection, and uterine perforation.
Laparoscopy. This procedure uses two or more small incisions, one at the navel, and one or more in the lower abdomen. Carbon dioxide gas is injected into the abdomen, distending it and pushing the bowel away. A laparoscope is inserted through the navel incision and a probe is inserted through a second incision above the pubic hairline. The probe allows the doctor to directly view the abdominal cavity, including the outer walls of the uterus, fallopian tubes, and ovaries. The doctor manipulates surgical instruments that are passed through additional small abdominal incisions, using the image of the uterus on the video monitor as the guide.

GnRH agonists, usually depo-Lupron or Synarel, are often used for 2 - 3 months before many uterine surgical procedures.

These drugs may help by:

Reducing the volume of fibroids by 40 - 60%, in some cases to the extent that a less invasive procedure may be performed
Reducing the risk of bleeding
Shortening surgical time
Reducing postoperative symptoms

Treatments may not be useful, however, for small fibroids, which may shrink to the point that they are no longer visible at the time of surgery. Since fibroids regrow after treatment, the problem would recur.

There has also been some question whether these drugs provide any additional advantages for myomectomies that use conventional surgical techniques. Ultrasound may be useful in helping to detect fibroids most likely to benefit from GnRH agonists before such a procedure.

A myomectomy surgically removes only the fibroids and leaves the uterus intact, often preserving fertility. Myomectomy may also help regulate abnormal uterine bleeding caused by fibroids. Not all women are candidates for myomectomy. If the fibroids are numerous or large, myomectomy can become complicated, resulting in increased blood loss. If cancer is found, conversion to a full hysterectomy may be necessary.

To perform a myomectomy, the surgeon may use standard surgical approaches (laparotomy) or less invasive ones (hysteroscopy or laparoscopy).

Laparotomy. Laparotomy uses a wide abdominal incision and conventional surgery. It is used for subserosal or intramural fibroids that are very large (usually more than 4 inches), that are numerous, or when cancer is suspected. Using this approach, the doctor may be able to feel the fibroids, particularly intramural types, which can be missed during laparoscopy or hysteroscopy. (The doctor can only view the uterine cavity or outside surface with these latter procedures.) After the fibroids are removed, careful reconstruction of the uterine wall is critical in both laparotomy and laparoscopy, so that bleeding and infection do not occur. While complete recovery takes less than a week with laparoscopy and hysteroscopy, recovery from a standard abdominal myomectomy takes as many as 6 - 8 weeks. It also poses a higher risk for scarring and blood loss than with the less invasive procedures, which is a concern for women who want to retain fertility.
Hysteroscopy. A hysteroscopic myomectomy may be used for submucous fibroids found in the uterine cavity. With this procedure, fibroids are removed using an instrument called a hysteroscopic resectoscope, which is passed up into the uterine cavity through the vagina and cervical canal. A wire loop carrying electrical current is then used to shave off the fibroid. In one study, nearly 60% of patients conceived after this procedure. However, it is not appropriate for many women.
Laparoscopy. Women whose uterus is no larger than it would be at a 6-week pregnancy and who have a small number of subserous fibroids may be eligible for treatment with laparoscopy. Laparoscopy requires incisions, but they are much smaller than with laparotomy. As with hysteroscopy, a thin scope is employed that contains surgical and viewing instruments. In centers with extensive experience, laparoscopy has fewer complications, and also shorter recovery time and lower costs than laparotomy. On the other hand, compared to the invasive surgery, laparoscopy has a greater chance for fibroid recurrence (over 16% at 5 years in one study), and a greater danger for a weakened uterine wall, which could threaten pregnancies.

Complications and Postoperative Factors. Any procedure for myomectomy is very complex. To reduce the risk for complication, patients should seek a surgeon experienced in myomectomies. Complications that occur during a myomectomy from any procedure include:

Excessive blood loss (occurs more often with laparotomy)
Uterine weakening and rupture during pregnancy (more of a concern with laparoscopy)
Development of scar tissue called adhesions (more common with laparotomy)
Infection
Damage to the bowel or bladder (more common with laparotomy)

Pregnancies After Myomectomy. Studies suggest that pregnancy can be restored in more than half of women after the procedure. In appropriate candidates, there appears to be no differences in fertility rates and pregnancy complications between laparotomy or laparoscopy. The best candidates for retaining fertility include women with pedunculated and superficial serosal fibroids (stalk-like fibroids that grow out from the uterine surface). Women with deep intramural fibroids are at higher risk for infertility after myomectomy.

Although studies indicate that between 40 - 58% of women become pregnant after myomectomy, only about a quarter of the women carry their babies to term. Women who become pregnant face a higher risk for cesarean section or miscarriage. It is unclear whether laparoscopic myomectomy weakens the uterine walls and poses a higher risk for rupture during pregnancy than laparotomy.

Recurrence of Fibroids and Recurrent Surgeries. The recurrence rate for fibroid growth after myomectomy is high. Between 11 - 26% of patients will have recurring fibroids that are severe enough to need additional treatment. One study suggested that women who had uteruses that were less than the equivalent size of a 12-week pregnancy and women who were overweight had a higher risk for needing repeat surgery.

Uterine Artery Embolization (UAE), also called uterine fibroid embolization (UFE), is a relatively new way of treating fibroids. UAE deprives fibroids of their blood supply, causing them to shrink. UAE is a minimally invasive radiology treatment and is technically a nonsurgical therapy. It is much less invasive than hysterectomy and myomectomy, and involves a shorter recovery time than the other procedures. The patient remains conscious, although sedated, during the procedure, which takes around 60 - 90 minutes.

The procedure is typically performed in the following manner:

The patient receives a sedative to cause drowsiness, and a local anesthetic is applied to the skin around the groin.
An interventional radiologist makes a small quarter-inch incision in the skin and inserts a catheter (a thin tube) into the femoral artery. The femoral artery is a large artery that begins in the lower abdomen and extends down to the thigh. The radiologist then threads the catheter into the uterine artery.
Small plastic particles are injected into the artery. These particles block the blood supply to the tiny arteries that feed fibroid cells, and the tissue eventually dies.
Patients usually stay in the hospital overnight after UAE and are given pain medication. Pelvic cramps are common for the first 24 hours after the procedure.
It takes 1 - 2 weeks for the patient to recover from the procedure and return to work. It may take 2 - 3 months for the fibroids to shrink enough so that symptoms improve.

Effect on Fertility. In general, UAE is considered an option for only those who have completed childbearing. Although UAE may protect fertility in many women, the procedure does pose some risk for ovarian failure and infertility. In 2004, the American College of Obstetricians and Gynecologists issued an opinion statement advising women who wish to have children that it is not yet known how this procedure affects their potential for becoming pregnant. A 2005 British study of 671 women who underwent UAE found that the procedure did not interfere with fertility. The study did find a slight increase in caesarean section delivery.

Complications and Postoperative Effects. UAE has a lower rate of complication than hysterectomy and myomectomy and a shorter hospital stay. Compared to other procedures, women who undergo UAE miss fewer days of work. Serious complications occur in less than 0.5% of cases, and no deaths have been associated with the procedure.

Pain. Abdominal cramps and pelvic pain after the procedure are nearly universal and may be intense. Pain usually begins soon after the procedure and typically plateaus by 6 hours. On-demand painkillers may be required. The pain usually improves each day over the next several days. A low-grade fever is also common in the first week after the procedure.
Fibroid slough. Around 2 – 3% of patients pass small fragments of fibroid tissue during the first few days after UAE. This can cause intense labor-like pain and also increase the risk for infection. Some women may require dilation and curettage (D&C) to make sure that infection does not develop.
Early menopause. Most women who have UAE will continue to have normal menstrual periods. Around 1 – 5% of women, however, experience menopause after the procedure. Menopause is more likely to occur in women over age 45 who undergo UAE.

Success Rates. Studies on uterine artery embolization show high patient satisfaction (over 90%) and low complication rates. A 2003 study reported 83% improvement in heavy bleeding, 77% reduction in menstrual cramps, and 85% improvement in urinary symptoms. Results from the first long-term UAE study, presented at the 2005 annual scientific meeting of the Society of Interventional Radiology, reported that 73% of women experienced symptom relief that lasted for 5 years. The success rate for UAE was comparable to that of myomectomy. A 2006 study reported a success rate of 89% for UAE compared to 100% for hysterectomy.

For around 10 - 20% of women, symptom control fails or fibroids reoccur. Some studies suggest that women with large fibroids are not good candidates for UAE.

In either endometrial ablation or endometrial resection, the entire lining of the uterus (the endometrium) is removed or destroyed. These procedures are useful for women with severe heavy menstrual bleeding, including some with fibroids. They are generally not useful for large fibroids. Standard resection uses an electrosurgical wire loop to surgically remove the lining. With ablation, uterine tissue is usually vaporized using a thin powerful laser beam or high electric voltage. Newer ablation procedures include balloon ablation (ThermaChoice) and techniques that use electric wands, freezing, hot saline, lasers, microwaves, and radiofrequency.

Myolysis, or laparoscopic leiomyoma coagulation, uses either lasers or electrosurgery to heat and coagulate and destroy the fibroid tissue. This approach may prove to be beneficial for women with fibroids that measure a diameter of 10 cm (about 4 inches) or less and that respond to hormone treatments with GnRH agonists.

Myolysis uses a needle or a Nd:YAG laser that rapidly punctures a number of holes in the fibroid, heating and destroying the tissue in various locations. This widespread destruction cuts off the blood supply and shrinks the fibroid over ensuing months. The uterus is left intact, but tissue destruction makes childbearing unlikely.

In one study, myolysis performed either alone or with endometrial resection was successful in avoiding the need for major surgery in 97% of women. Advanced techniques that are performed by surgeons who are highly skilled in the procedure may make it possible to destroy even large intramural fibroids, but further study is required.

In most cases, patients return home the same day and can return to normal activities within a week. There are few side effects. However, as the fibroids degenerate over time, many women report considerable pain.

MRgFUS is a non-invasive procedure that uses high-intensity ultrasound waves to heat and destroy (ablate) uterine fibroids. This “thermal ablation” procedure is performed with a device that combines magnetic resonance imaging (MRI) with ultrasound. The FDA approved this device, the ExAblate 2000 System, in 2004.

During the 3-hour procedure, the patient lies inside an MRI machine. The patient receives a mild sedative to help relax but remains conscious throughout the procedure. The radiologist uses the MRI to target the fibroid tissue and direct the ultrasound beam. The MRI also helps the radiologist monitor the temperature generated by the ultrasound.

MRgFUS is appropriate only for women who have completed childbearing or who do not intend to become pregnant. The procedure cannot treat all types of fibroids. Fibroids that are located near the bowel and bladder, or outside of the imaging area, cannot be treated.

Research presented at the 2005 Radiological Society of North America annual meeting reported that MRgFUS helps improve fibroid symptoms and reduce fibroid size. A 2006 study indicated that the procedure provides symptom relief for up to 1 year. Another 2006 study indicated that pre-treatment with GnRH-agonist drugs before the MRgFUS procedure may help improve outcomes. However, because this procedure is new and long-term results are not yet available, some insurance companies do not pay for this treatment.

Hysterectomy

Presence of symptoms (pelvic pain, bleeding, symptomatic fibroids)
Lack of symptom improvement or resolution despite treatment
Previous use of GnRH agonist drugs

The number of procedures has continued to increase, but the rise has slowed substantially in recent years. The percentage of hysterectomies performed because of fibroids, however, has risen significantly. Fibroids now account for 38% of these operations, but the rates vary widely by ethnic group. In a major 2002 government report, 68% of fibroid-related hysterectomies were performed in African-American women, 33% in Caucasians, and 45% among women of other ethnic groups.

Most women are satisfied with the procedure. A major analysis on hysterectomies reported that symptoms related to menstrual problems decline significantly in most women (although none completely disappear for all women). Most women also experience improved quality of life and mood. Women who have a hysterectomy are less likely to experience hot flashes than women who have a natural menopause.

Still, in one study in 70% of cases when doctors recommended hysterectomies, they did not give their patients alternative choices or adequate diagnostic evaluations. Any woman, even one who has reached menopause, uncertain about a recommendation for a hysterectomy for fibroids should certainly seek a second opinion.

Once a decision for a hysterectomy has been made, the patient should discuss with her doctor what will be removed. The common choices are:

Total Hysterectomy (removal of uterus and cervix).
Supracervical Hysterectomy (removal of uterus and preservation of the cervix); performed in about 20 - 25% of cases.
Bilateral Salpingo-Oophorectomy (removal of the fallopian tubes and ovaries); used with either total or supracervical hysterectomy.

Total Hysterectomy. In a total hysterectomy the uterus and cervix are removed, which eliminates the risk of uterine and cervical cancer. (Given technical advances and growing surgical experience, a total hysterectomy may eventually be unnecessary except in special circumstances, such as when cancer is present.)

Supracervical Hysterectomy. In a supracervical hysterectomy (also called subtotal hysterectomy) the uterine body is removed, and the cervix is retained. Retaining the cervix helps support the pelvic floor and may help maintain full sexual sensation, but the risk for cervical cancer remains. Women may experience cyclical bleeding for up to a year after surgery.

Bilateral Oophorectomy. Bilateral oophorectomy is the removal of both ovaries. (When only one ovary is removed, the procedure is called oophorectomy.) Bilateral salpingo-oophorectomy is the removal of both fallopian tubes and ovaries. These procedures may be performed with either total or supracervical hysterectomy. When deciding to remove the ovaries, a woman must be aware of various consequences, both positive and negative.

Oophorectomy helps to reduce the risk for ovarian cancer, by elimination of ovaries, and breast cancer, by causing estrogen loss. Ovarian cancer is very rare, in any case, except in women with a family history of the disease. Even in these women, removal is not 100% preventive. Cancer can still develop from cancer cells that may be present in the lining of the pelvis (the peritoneum).
Removal of the ovaries ceases estrogen and testosterone production, which can increase the risk for menopause-related conditions. These include osteoporosis, heart disease, skin wrinkling, and reduced muscle tone. Estrogen replacement, however, can help offset these problems. Women who have a bilateral oophorectomy and do not receive hormone replacement therapy may experience more severe hot flashes than women who enter menopause naturally.

Abdominal Hysterectomy. Abdominal hysterectomy is the most common procedure and is used in over 80% of hysterectomies in African American women and about 60% in Caucasian and other ethnic groups. It is best suited for women with large fibroids, when the ovaries need to be removed, or when cancer or pelvic disease is present. With the abdominal procedure, a wide incision is required to open the abdominal area from which the surgeon removes the uterus. If possible, the incision should cut horizontally across the top of the pubic hairline (the bikini incision). This incision heals faster and is less noticeable than a vertical incision, which is used in more complicated cases. The patient may need to remain in the hospital for 3 - 4 days, and recuperation at home takes about 4 - 6 weeks.

Vaginal Hysterectomy. Vaginal hysterectomy requires only a vaginal incision through which the uterus is removed. This approach is most often performed for small fibroids (although advances in imaging and other techniques may allow it to be used on larger fibroids). At this time, it is used in fewer than 20% of African-American women and slightly under 40% of Caucasians and other groups.

A variation of the vaginal approach is called laparoscopic-assisted vaginal hysterectomy (LAVH). It uses several small abdominal incisions through which the surgeon severs the attachments to the uterus and ovaries. They can then be removed through the vaginal incision, as in the standard approach. Hospital stays may be longer and costs are greater than with standard vaginal hysterectomy. The use of LAVH has risen significantly and is used in over a quarter of vaginal procedures. LAVH is very costly and time consuming, however, and some experts question whether it adds any significant benefits compared to the standard vaginal procedure.

The patient should ask a family member or friend to help out for the first few days at home. The following are some of the precautions and tips for postoperative care:

For a day or two after surgery, the patient is given medications to prevent nausea and painkillers to relieve pain at the incision site.
As soon as the doctor recommends it, usually within a day of the operation, the patient should get up and walk in order to help prevent pneumonia, reduce the risk of blood-clot formation, and speed recovery.
Walking and slow, deep breathing exercises may help to relieve gas pains, which can cause major distress for the first few days.
Coughing can cause pain, which may be reduced by holding a pillow over a surgical abdominal wound or by crossing the legs after vaginal surgery.
Patients are advised not to lift heavy objects, not to douche or take baths, and not to climb stairs or drive for several weeks.
For the first few days after surgery, many women weep frequently and unexpectedly. These mood swings may be due to depression from the loss of reproductive capabilities and from abrupt changes in hormones, particularly if the ovaries have been removed.

The patient should discuss with the doctor when exercise programs more intense than walking can be started. The abdominal muscles are important for supporting the upper body, and recovering strength may take a long time. Even after the wound has healed, the patient may experience an on-going feeling of overall weakness, which can be demoralizing, particularly in women used to physical health. Some women do not feel completely well for as long as a year while others may recover in only a few weeks.

More serious complications, such as those described below, are uncommon, but patients should be aware of their symptoms and call the doctor immediately if they occur.

Infection. Infection occurs in 10 - 15% of patients, the risk being higher with abdominal than with vaginal surgery. Risk factors for infection include obesity, a longer than normal operative time, and low socioeconomic status. Patients should be aware of any symptoms and call the doctor immediately if they occur. Symptoms of infection include:

Continuing or increasingly severe pain
Fever
Heavy discharge
Bleeding (antibiotics given at the time of surgery help to reduce this risk)

Other Serious Complications. Other serious and even life-threatening complications are rare but can include:

Pulmonary embolism (blood clots that travel to the lung).
Surgical injury of the urinary or intestinal tracts.
Abscesses.
Perforation of the bowel.
Fistulas (a passage that bores from an organ to the skin or to another organ).
Dehiscence (opening of the surgical wound).

Long-Term Complications. Women who have had a total hysterectomy are at higher risk for the following long-term complications:

Muscle weakness in the pelvic area.
Prolapse (descent) of the bladder, vagina, and rectum if the muscle's walls are overly weakened; may require further surgery.
Bowel problems if adhesions (extensive scarring) have formed and obstruct the intestines; may require additional surgery.
Shortening of the vagina is a possible complication specific to vaginal hysterectomy. It can cause pain during intercourse.

Such complications are uncommon.

Two procedures associated with hysterectomy may affect sexuality directly:

Although the clitoris can trigger orgasm even if the cervix is removed, many experts believe that uterine contractions stimulated by sexual intercourse also cause a so-called “deep orgasm.” Retaining the cervix may help to retain this sensation. However, a 2006 review found that women who undergo a total hysterectomy (removal of both uterus and cervix) are no more likely to have sexual difficulties or problems with urinary and bowel function than women who have only their uterus removed.
Patients who have both ovaries removed may be at higher risk for loss of sexuality. Ovaries produce small amounts of testosterone (the male hormone responsible for sexual drive) even after menopause.

Testosterone Replacement. Testosterone replacement therapy may restore sexuality in women who experience a decline in sexual drive. Occasionally, oral or injection treatments can produce male characteristics such as facial hair and voice change. A slow-release pellet inserted every 6 months under the skin in the hip appears to reduce these side effects. Taking hormones long term almost always carries some risk, and it is not yet known what danger testosterone replacement may pose in women.
