Posterior vaginal wall defects and their relation to measures of pelvic floor neuromuscular function and posterior compartment symptoms.
OBJECTIVE
The purpose of this study was to describe the pelvic floor neuromuscular function and posterior compartment symptoms in patients with posterior vaginal wall prolapse.


METHODS
Two hundred twenty-seven women who were referred to a urogynecology and urology clinic were enrolled prospectively. Each patient completed a health history questionnaire and standardized physical examination that specifically graded uterovaginal prolapse according to the pelvic organ prolapse quantification system.


RESULTS
Sixty-nine women had a pelvic organ prolapse quantification system point (most dependent portion of the posterior vaginal wall during straining as measured from the hymeneal ring) of < or =-1. Older age, a history of hysterectomy, a genital hiatus of >3 cm (48% vs 24%; P =.002), and perineal descent of > or =2 cm (14% vs 5%; P =.042) were significantly more common in women with posterior vaginal prolapse. When women with posterior prolapse and symptomatic complaints were compared with asymptomatic women with prolapse, a perineal descent of > or =2 cm (21% vs 0%; P =.004) was significantly more common in the symptomatic group.


CONCLUSIONS
Pelvic floor neuromuscular function should be related to posterior vaginal prolapse and symptoms; however, only perineal descent appears associated strongly with both symptoms and prolapse in this population.
