Uterine prolapse
Uterine prolapse is when the uterus descends towards or through the opening of the vagina. Symptoms may include vaginal fullness, pain with sex, trouble urinating, urinary incontinence, and constipation. Often it gets worse over time. Low back pain and vaginal bleeding may also occur.Risk factors include pregnancy, childbirth, obesity, constipation, and chronic coughing. Diagnosis is based on examination. It is a form of pelvic organ prolapse, together with bladder prolapse, large bowel prolapse, and small bowel prolapse.Preventive efforts include managing chronic breathing problems, not smoking, and maintaining a healthy weight. Mild cases may be treated with a pessary together with hormone replacement therapy. More severe cases may require surgery such as a vaginal hysterectomy. About 14% of women are affected. It occurs most commonly after menopause.

Causes
The most common cause of uterine prolapse is trauma during childbirth, in particular multiple or difficult births. About 50% of women who have had children develop some form of pelvic organ prolapse in their lifetime. It is more common as women get older, particularly in those who have gone through menopause. This condition is surgically correctable.

Pathophysiology
The uterus (womb) is normally held in place by a hammock of muscles and ligaments. Prolapse happens when the ligaments supporting the uterus become so weak that the uterus cannot stay in place and slips down from its normal position. These ligaments are the round ligament, uterosacral ligaments, broad ligament and the ovarian ligament. The uterosacral ligaments are by far the most important ligaments in preventing uterine prolapse.
In some cases of uterine prolapse, the uterus can be unsupported enough to extend past the vaginal wall for inches.

Treatment
Treatment is conservative, mechanical or surgical.

Conservative
Conservative options include behavioral modification and muscle strengthening exercises such as Kegel exercise.  Pessaries are a mechanical treatment that supports the vagina and elevates the prolapsed uterus to its normal, correct position. Pessaries are frequently offered as a first-line treatment for uterine prolapse.

Surgery
Surgical options are many and may include a hysterectomy or a uterus-sparing technique such as laparoscopic hysteropexy, sacrohysteropexy or the Manchester operation.
In the case of hysterectomy, the procedure can be accompanied by sacrocolpopexy.  This is a mesh-augmented procedure in which the apex of the vagina is attached to the sacrum by a piece of medical mesh material.A Cochrane review found that sacral colpopexy was associated with lower risk of complications than vaginal interventions, but it was unclear what route of sacral colpopexy should be preferred.  No clear conclusion could be reached regarding uterine preserving surgery versus vaginal hysterectomy for uterine prolapse. The evidence does not support use of transvaginal mesh (TVM) compared to native tissue repair for apical vaginal prolapse. The use of a transvaginal mesh is associated with side effects including pain, infection, and organ perforation. According to the FDA, serious complications are "not rare".

Society and culture
A number of class action lawsuits have been filed and settled against several manufacturers of TVM devices.
