BELIEVE trial: Bulking versus Sling for Treating Stress Urinary Incontinence at the time of Vaginal

UCI Specialty Area: Urology
Principal Investigator: Olivia Chang
Official Title: BELIEVE trial: Bulking versus Sling for Treating Stress Urinary Incontinence at the time of Vaginal Prolapse Repair
A Study On:
Genital Bladder - Genitourinary
Pelvic Organ Prolapse
Urinary Incontinence

Study Description

This will be a double-blinded, non-inferiority, controlled trial utilizing a 1:1 randomization scheme to assign patients to each treatment arm (PAHG vs. RP-MUS). Patients undergoing PAHG will be given sham incisions in order to mask the type of SUI procedure they underwent. This will consist of two "earring-hole" sized superficial scratches in the epidermis and fibrin glue applied to the expected suprapubic exit sites for the RP-MUS. Sham incisions are not associated with an increased risk of infection and are considered low risk. Validated symptom questionnaires will be administered to the patient by a study investigator prior to surgery and at 1, 6, 12, and 24 months. At the final study visit, patients will be un-blinded and provided information on which SUI procedure they underwent. Unless it is necessary for subsequent care, as in the case of a procedure specific complication like a mesh erosion, patients who might require additional intervention for recurrent SUI during the study period will remain blinded to their initial treatment assignment. If patients request this information, they will be informed that they would need to exit the study, however their data would still be analyzed as part of the intention to treat protocol. Data of patients who dropout will be analyzed in the same manner. Pelvic organ prolapse procedures will be limited to native tissue repairs only and may include either or both apical and non-apical repair procedures; selection of appropriate POP repair procedure will be at the surgeon's discretion. All randomized patients will complete surveys at 12 and 24 months will assess patient recovery, satisfaction with care, and calibrating surveyed and clinically assessed outcomes to their daily life experiences. Based on prior similar studies, this number is sufficient to ensure saturation of themes83. Between 8 to 20 participants in each arm will be randomly selected from across all sites to participate in individual semi-structured telephone interviews preoperatively, at 12 months and at 24 months after surgery.
