Pelvic organ prolapse (POP) occurs when the muscles, ligaments, and connective tissue that support the pelvic organs — the bladder, uterus, vagina, and rectum — weaken or stretch, allowing one or more organs to drop from their normal position and bulge into or out of the vagina.
POP is extremely common: it affects up to 50% of women at some point in their lives, and nearly 1 in 9 women will undergo surgery for prolapse or incontinence by age 80. Despite how common it is, many women feel isolated or embarrassed — but prolapse is not dangerous and is very treatable.
Types of Prolapse
Anterior Compartment
- Cystocele — the bladder drops into the front wall of the vagina. Often called a "dropped bladder."
- Urethrocele — the urethra bulges into the vaginal wall (often combined with a cystocele).
Posterior Compartment
- Rectocele — the rectum bulges into the back wall of the vagina.
- Enterocele — the small intestine bulges into the upper vaginal wall.
Apical (Top) Compartment
- Uterine prolapse — the uterus descends into the vagina.
- Vaginal vault prolapse — after hysterectomy, the top of the vagina drops down.
Multiple Compartments
Most women have prolapse in more than one compartment. A careful exam identifies each affected area so treatment can address all of them together.
