Abstract

Abstract : Importance: Concomitant surgery for stress urinary incontinence (SUI) during pelvic organ prolapse (POP) operations are debated. Objectives: We aimed to assess the risk of an SUI operation after a uterine prolapse operation and compare the risk after the Manchester procedure versus vaginal hysterectomy. Study Design: We performed a nationwide historical cohort study including women with no history of hysterectomy undergoing the Manchester procedure (n = 6065) or vaginal hysterectomy (n = 9, 767) for POP during 1998 to 2018. We excluded women with previous surgery for SUI and POP, concomitant surgery for SUI (n = 34, 0.2%), and diagnosed with gynecological cancer before or within 90 days from surgery. Women were followed up until SUI operation/death/emigration/diagnosis of gynecological cancer/December 31, 2018, whichever came first. Women undergoing the Manchester procedure were censored if they had undergone hysterectomy. We assessed the rate of SUI surgery with cumulative incidence plots. We performed Cox Regression to analyze the risk of SUI surgery, adjusting for age, calendar year, income level, concomitant surgery in anterior and posterior compartments, and diagnosis of SUI before POP operation. Results: We found that 12.4% women with and 1.6% without SUI diagnosed before the POP surgery who underwent SUI surgery within 10 years. During follow-up (median, 8.5 years), 129 (2.1%) underwent SUI surgery after the Manchester procedure and 175 (1.8%) after vaginal hysterectomy (adjusted hazard ratio, 1.06 [0.84–1.35]). Conclusions: Of women diagnosed with SUI before POP operation 1 in 8 subsequently underwent SUI surgery. Few women not diagnosed with SUI subsequently underwent SUI surgery. There was no difference in risk of SUI after the Manchester procedure and vaginal hysterectomy.
