Prolapse of pelvic organs such as the bladder, rectum, bowel and uterus have rapidly increased over the years as the baby boomer generation ages and the traumas of childbearing become apparent. Many women are either too shy or too embarrassed to even bring up the problem with their physicians. While it may be an embarrassing topic, living with these conditions without seeking medical help has consequences.
How Does it Happen?
The origin of a pelvic organ prolapse can usually be traced to the weakening of tissues as a baby passes through the birth canal. This stretching an tearing of tissues gradually worsens over time as gravity and estrogen loss results in the loss of collagen in the vaginal tissues and various muscles, fascia (bands of fibrous connective tissue), and ligaments. Babies born today are usually larger than those born a few generations ago, causing more trauma during birth. In addition, women today are heavier and have more weight pushing on their pelvic organs. It also doesn’t help if one is a smoker. The loss of connective tissue and the chronic smoker’s cough also factor in. a coughing asthmatic or one with chronic bronchitis is also more prone to prolapse and incontinence. Occasionally, these problems occur in women who have never had children or have had cesarean sections. This is explained by one’s inherited weakness of supporting structure.
A Look at the Symptoms
The general symptoms of pelvic organ prolapse include a sensation of fullness or heaviness in the vaginal region. A woman finds a bulge starting to protrude through the vaginal opening. Sometimes the entire vagina or uterus may protrude between a woman’s legs.
Others find physical activity difficult because of the incontinence that often accompanies the prolapse. It takes a careful examination by a gynecologist or urogynecologist to precisely diagnose whether the defect is a cystocele/urethrocele (bladder and urethral prolapse), a rectocele (rectal prolapse into the vagina), an enterocele (small bowel into the vagina) or a uterine prolapse (the uterus descending down the vaginal canal).
Diagnosis of pelvic prolapse includes a complete history and physical examination. “Bladder studies,” performed with a computerized machine, are often required to make a specific diagnosis.
Treatment Options
Nonsurgical Treatments include the use of pessaries. These are latex, or rubber devices that are placed inside the vagina to hold back the prolapsing structures. Some women even find the use of a tampon to function a similar manner. Unfortunately, the well-known Kegel exercises have essentially no effect on pelvic organ prolapse but may be helpful for incontinence.
Surgery is often needed to repair the weakened tissues that bulge into and out of the vagina. However, surgical repair of the cystocele remains one of the most difficult challenges in female pelvic floor reconstruction. Failure rates of traditional “anterior colporrhaphy” range from 20 to 40 percent. New techniques using biologic tissue or polypropylene mesh have dramatically reduced these failures to less than 10 percent. Unfortunately, most gynecologists, urologists, and even urogynecologists have not been trained in laying down tissue or mesh in the repair of these vaginal hernias. The use of tissues, such as human or pig dermis carries its own risks, including rejection and infection. The use of polypropylene mesh also has added risks of erosion into the vagina or bladder.
With improving techniques and technology, these risks have been lowered, and acceptance of these methods in the United States has increased dramatically. The European and Australian medical communities are about five years ahead of the United States. They deserve the credit for the changes affecting American urogynecology today.
