Abstract

OBJECTIVE: The objective was to determine whether the addition of prophylactic retropubic colposuspension is superior to no anti-incontinence procedure during minimally invasive surgical sacrocolpopexy for stress-continent patients in decreasing rates of postoperative de novo stress urinary incontinence (SUI).

METHODS: In this randomized superiority trial, we recruited stress-continent prolapse patients undergoing either conventional or robotic-assisted laparoscopic sacrocolpopexy with negative preoperative supine cough stress tests. Patients were randomized to receive either prophylactic retropubic colposuspension or no retropubic colposuspension (control). The primary outcome was the composite measure of postoperative de novo SUI at 3 months, which included either (1) "Yes" to Question #17 on the Pelvic Floor Distress Inventory-20 endorsing symptoms of urinary leakage with coughing, sneezing, laughing, (2) positive retrofill cough stress test, or (3) any SUI treatment after sacrocolpopexy. Using data from the Colpopexy and Urinary Reduction Efforts trial, a sample size of 42 participants would demonstrate the addition of prophylactic retropubic colposuspension to be superior to control with a superiority margin of 15%.

RESULTS: Fifty patients underwent randomization, with 26 assigned to prophylactic retropubic colposuspension and 24 as controls. Three months after surgery, 50.0% of the patients in the retropubic colposuspension group and 41.7% of controls met one or more…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 42 participants or records.
