Clinical Trial Summary

The primary aim of this double-blind, randomized clinical trial (RCT) is to test the hypothesis that the addition of a standardized technique of interpositional synthetic polypropylene mesh placement improves the one-year outcome of vaginal reconstructive surgery for anterior prolapse compared to traditional vaginal reconstructive surgery without mesh.

Description:

Multiple vaginal, abdominal and laparoscopic procedures have been described for surgical correction of pelvic support problems. However, conventional pelvic reconstructive surgeries have been associated with a 20-30% prolapse recurrence rate. The anterior vaginal wall is the site most often recognized as the area of vaginal prolapse recurrence. Minimally invasive surgical procedures using mesh have rapidly developed in the field of pelvic floor reconstruction in an attempt to improve surgical cure rates. Unfortunately, safety and efficacy data have lagged behind the technical advancements. This trial will randomize women with advanced anterior wall prolapse to two treatment arms: vaginal reconstructive surgery with mesh and vaginal reconstructive surgery without mesh. The primary outcome is cure of anterior wall prolapse at one year. Secondary outcomes are cure of apical and posterior wall prolapse, quality-of-life measures and complication rates. Patients will be approached for recruitment only after they have made the decision to undergo vaginal surgery for anterior prolapse. The patient and examiner will be blinded to the surgical treatment assignment. Interim measurement of primary and secondary outcomes will be conducted three months post-operatively. Additional follow-up will be conducted at one-year intervals subsequent to the expected one-year endpoint.
