OBJECTIVE: To retrospectively compare surgical success and complications between vaginal vault prolapse compared with uterovaginal prolapse in women who underwent apical prolapse repair for stage II-IV prolapse. METHODS: Women in one of three Pelvic Floor Disorders Network prolapse surgical trials were included. Absence of bothersome bulge symptoms, no prolapse beyond the hymen, and no subsequent prolapse treatment defined success and was our primary outcome. Secondary outcomes included comparison of quality-oflife measures, anatomic changes, and adverse events. Pelvic organ prolapse quantification (POP-Q) and quality-of-life measures were administered at baseline and 1-2 years postoperatively. Comparisons were controlled for study site, age, body mass index, baseline POP-Q, apical and anterior or posterior repair performed, and prior prolapse repair. Outcomes measured at multiple time points were analyzed using longitudinal models to assess whether differences existed across study follow-up. RESULTS: Four hundred twenty-one women underwent vault prolapse, and 601 underwent uterovaginal prolapse apical repair. The vault prolapse group was older, more likely to be white, and to have prior urinary incontinence or prolapse repair, stage IV prolapse, and more prolapse bother on a validated scale (all P#.034). The vault prolapse group was more likely to undergo sacrocolpopexy (228/421 [54%] vs 93/601 [15%]); the uterovaginal prolapse group was more likely to undergo vaginal repair (508/601 [85%] vs 193/421 [46%] P,.001). There were no differences in success (odds ratio [OR] 0.76 for vault prolapse vs uterovaginal prolapse, 95% CI 0.51-1.15, P5.20), changes in Pelvic Organ Prolapse Distress Inventory scores (279.4 vs 279.8, P5.89), postoperative POPQ point C measurements (27.0 vs 27.1 cm, P5.41), or serious adverse events (86/421 [20%] vs 90/601 [15%], P5.86) between groups. Among women who underwent a vaginal approach for repair of vault prolapse (n5193) or uterovaginal prolapse (n5508), there were no differences in success rates (OR 0.67, 95% CI 0.43-1.04, P5.09) at 1-2 years postoperatively. CONCLUSION: Surgical success of stage II-IV vault prolapse and uterovaginal prolapse apical repair was similar whether performed vaginally or abdominally at 1-2 years postoperatively.
