Urgency, detrusor overactivity and posterior vault prolapse in women who underwent pelvic organ prolapse repair.

Introduction: We investigated the relationship between posterior vault prolapse and overactive bladder (OAB) symptoms or detrusor overactivity (DO) and their changes after surgical repair.

Methods: Forty-three patients with vault prolapse and prevalent posterior compartment prolapse underwent pelvic organ prolapse repair surgery: 28 received colposacropexy and 15 were treated by the vaginal approach. Subjective success was lack of prolapse-related symptoms or urgency. OAB symptoms, voiding symptoms and constipation were evaluated. Patient satisfaction was defined by a visual analog scale score (range 0-10). Objective anatomical success was defined as no vaginal prolapse of stage ≥2 at any vaginal site.

Results: The median follow-up was 75 months (range 24-143). Preoperatively, 33/43 patients (76.74%) reported urgency. DO was found in 11/43 patients (25.6%), and 22/43 patients reported constipation. The anatomical outcome showed 2 persistent stage II rectoceles (6.9%). After surgery, OAB symptoms disappeared in 25/33 (75.88%) and persisted in 8 patients (24.2%); there was no de novo urgency. DO disappeared in 8/11 subjects (72.7%). Preoperative constipation was present in 17/33 patients with OAB symptoms (51.5%) and disappeared postoperatively in 13/17 patients (76.4%) (p < 0.013). De novo constipation appeared in 3 patients (associated with OAB in 2 patients).

Conclusions: Prevalent posterior compartment pelvic organ prolapse and OAB/DO were often associated. After surgery, OAB symptoms and DO were significantly reduced.
