The pelvic organ prolapsequantification (POP-Q) exam is used to quantify, describe, and stage pelvic support.

There are 6 points measured at thevagina with respect to the hymen.

Points above the hymen are negative numbers; points belowthe hymen are positive numbers.

Point Description Range of ValuesAa Anterior vaginal wall 3 cm proximal to -3 cm to +3 cm

the hymenBa Most distal position of the remaining upper -3 cm to + tvl

anterior vaginal wallC Most distal edge of cervix or vaginal cuff scarD Posterior fornix (N/A if post-hysterectomy)Ap Posterior vaginal wall 3 cm proximal to -3 cm to +3 cm

A prolapse occurs when pelvic organs drop from their natural position and sometimes protrude. There are several different types of prolapse. Often a woman can have more than one type of prolapse

The following tabs present common types and stages of prolapse. See the inside front cover to learn more about the pelvic organ prolapse quantification (POP-Q) exam.

In uterine prolapse, pelvic support structures break down and the uterus drops into the vagina. Most often, other pelvicorgans are also out of place.

For a woman who has undergone a hysterectomy, the top of the vagina (or vaginal cuff) can push into the lower vagina. This is called vaginal vault prolapse.

Women with vaginal vault prolapse often have a prolapse of the small intestine called an enterocele. In this type of enterocele, the small intestine drops through support tissue and into the vagina.

Anterior wall prolapse (or cystocele) isthe most common type of pelvic floor defect. It occurs when the anterior wall of the vaginaloses its support. As a result, the bladder drops and rotates into, and often out of, the vaginal opening. Some cystoceles can causeurine leakage while large cystoceles can cause difficulty voiding.

A posterior wall prolapse (or rectocele)occurs when the posterior wall of the vagina loses its support. As a result, the rectum can bulge into, and often out of, the vaginal opening. A large rectocele canmake it difficult to move the bowels.
