Pelvic organ prolapse is a medical condition that occurs when the normal support of the vagina is lost, resulting in sagging or dropping of the bladder, urethra, cervix, and rectum. As the prolapse of the vagina and uterus progresses, women can feel bulging tissue protruding through the opening of the vagina.

Types of pelvic organ prolapse

Over 50% of women experience the involuntary loss of urine in their lifetime, but fortunately there are many excellent available treatments. The two most common types of urinary incontinence are stress incontinence — leakage with coughing, laughing, sneezing, exercise, etc. — and urge incontinence, a feeling that you have to constantly urinate with or without urine leakage.


A wide array of treatment options, ranging from behavioral and diet changes all the way through surgical options exist, and are being used every day to help women recover parts of their lives they may have let go.

Weakening and stretching of the back wall of the vagina allows the rectum to bulge into and out of the vagina. Most often, the damage to the back wall of the vagina occurs during vaginal childbirth, although not everyone who has delivered a child vaginally will develop a rectocele.

Mild rectoceles rarely cause symptoms. However, straining with constipation puts significant pressure on the weak vaginal wall and can further thin it out. Avoiding constipation may prevent progression and also reduce symptoms from the rectocele.

Some women may find benefit from pelvic floor muscle strengthening and vaginal pessaries. When these low-risk interventions are insufficient to relieve symptoms, surgery is performed to reinforce the posterior vaginal wall.

When the supporting ligaments and muscles of the pelvic floor that keep the uterus in the pelvis are damaged, the cervix and uterus descend into and eventually out of the vagina. Often, uterine prolapse is associated with loss of vaginal wall support (cystocele, rectocele). When the cervix protrudes outside the vagina, it can develop ulcers from rubbing on underwear or protective pads. There is a risk that these ulcers will bleed and become infected. As with other forms of prolapse, it is not until the uterine descent is bothersome that treatment is necessary.

Women who have uterine prolapse often report pelvic pressure, the need to sit or lay down to relieve the discomfort, a sensation that their insides are falling out, difficulty emptying their bladder, and urine leakage. Strengthening the pelvic muscles with Kegel exercises, avoiding heavy lifting, constipation, and weight gain may reduce the risk of progression of uterine descent. Additional treatment options include pessary devices which provide support when worn or surgery.

If a woman has already had a hysterectomy, the very top of the vagina (where the uterus used to be) can become detached from its supporting ligaments. This can result in the tube of the vagina turning inside out. This condition is also known as vaginal “vault” prolapse. Depending upon how extensively the top of the vagina is turning inside out, one or several pelvic organs, such as the bladder, small and large bowel, will prolapse into the protruding bulge.

Symptoms depend on which organs prolapse. When the bladder is involved, women report difficulty in starting to urinate, and emptying their bladder well. If it is the bowel, then many report the need to push up the vaginal bulge and strain to have a bowel movement. Skin sores may develop if the bulge is rubbing on pads or underwear. A pessary may provide support for the bulge otherwise surgery is recommended.


Some loss of support is a very common finding upon physical exam in women, many of whom do not have bothersome symptoms. Those women who are uncomfortable often describe the very first signs as subtle — such as an inability to keep a tampon inside the vagina, dampness in the underwear, or discomfort due to dryness during intercourse.

As the prolapse gets worse, some women complain of:

  • A bulging pressure or heavy sensation in the vagina that worsens by the end of the day or during bowel movements
  • The feeling that they are “sitting on a ball”
  • Needing to push stool out of the rectum by placing their fingers into the vagina during bowel movement
  • Difficulty starting to urinate, a weak or spraying stream of urine
  • Urinary frequency or the sensation that they are not emptying their bladder well
  • The need to lift up the bulging vagina or uterus to start urination
  • Urine leakage with intercourse

Causes and risk factors

By studying large numbers of women with and without prolapse, researchers and urogynecologists have identified certain risk factors that predispose, cause, promote or worsen pelvic organ prolapse. The strength of our bones, muscles, and connective tissue are influenced by our genes and our race. Some women are born with weaker tissues and are therefore at risk to develop prolapse. Caucasian women are more likely than African American women to develop pelvic organ prolapse. Loss of pelvic support can occur when any part of the pelvic floor is injured during vaginal delivery, surgery, pelvic radiation, or back and pelvic fractures during falls or motor vehicle accidents.


Hysterectomy and other procedures done to treat pelvic organ prolapse also are associated with future development of prolapse. Some other conditions that promote prolapse include:

  • Constipation and chronic straining
  • Smoking
  • Chronic coughing
  • Heavy lifting
  • Obesity

Obesity, like smoking, is one of the few modifiable risk factors. Women who are obese have a 40 to 75% increased risk of pelvic organ prolapse. Aging, menopause, debilitating nerve, and muscle diseases contribute to the deterioration of pelvic floor strength and the development of prolapse.


It is estimated that nearly 50% of all women between the ages of 50 and 79 have some form of prolapse. The lifetime risk that a woman will have surgery for the correction of prolapse or urinary incontinence in the United States is about 11%. We also know that only one-third of these women will undergo repeat corrective surgery for these conditions. Approximately 300,000 procedures for correction of pelvic organ prolapse are performed nationwide each year. Many more women manage their prolapse without surgery.
