The Design of a Randomized Trial of Vaginal Surgery for Uterovaginal Prolapse: Vaginal Hysterectomy With Native Tissue Vault Suspension Versus Mesh Hysteropexy Suspension (The Study of Uterine Prolapse Procedures Randomized Trial).
OBJECTIVES: We present the rationale for and design of a randomized controlled superiority trial comparing 2 vaginal surgical approaches for the treatment of uterovaginal prolapse. The Study of Uterine Prolapse Procedures Randomized Trial (SUPeR) trial compares the efficacy and safety of native tissue repair with vaginal hysterectomy and suture apical suspension versus uterine conservation with mesh hysteropexy through 36 to 60 months postoperatively for primary repair of uterovaginal prolapse. METHODS: The selection of the primary outcome measure, timing of randomization, patient and evaluator masking to surgical intervention, collection and adjudication of adverse events, cost effectiveness evaluations, partnering with industry, and surgeon certification of competency to perform the 2 procedures is described. A composite primary outcome of success defined as no prolapse symptoms, no objective prolapse beyond the hymen, and no retreatment of prolapse, with a minimum of 36 months postsurgery follow-up using survival analyses is planned. Secondary outcomes measured at baseline and every 6 months postsurgery include validated condition-specific and general quality of life assessments, global impression of improvement, body image, and sexual function measures. Unique challenges during the trial design include maintenance of patient masking to the intervention with routine gynecologic health maintenance and maintenance of evaluator masking. RESULTS: Recruitment and randomization of 180 participants is complete, and participants are currently in the follow-up phase. CONCLUSIONS: This trial will provide information to help surgeons counsel patients and contribute evidence-based information regarding risks and benefits of 2 approaches for the treatment of uterovaginal prolapse.
