Rates and Risk Factors for Future Stress Urinary Incontinence Surgery after Pelvic Organ Prolapse Repair in a Large Population-based Cohort in California.

OBJECTIVES: To determine the rate and risk factors for future stress urinary incontinence (SUI) surgery in a large population-based cohort of previously continent women following pelvic organ prolapse (POP) repair without concomitant SUI treatment.

METHODS: Data from the Office of Statewide Health Planning and Development were used to identify all women who underwent anterior, apical, or combined anteroapical POP repair without concomitant SUI procedures in the state of California between 2005 and 2011 with at least 1-year follow-up. Patient and surgical characteristics were explored for associations with subsequent SUI procedures.

RESULTS: Of 41,689 women undergoing anterior or apical POP surgery, 1,504 (3.6%) underwent subsequent SUI surgery with a mean follow-up time of 4.1 years. Age (odds ratio [OR] 1.01), obesity (OR 1.98), use of mesh at the time of POP repair (OR 2.04), diabetes mellitus (OR 1.19), white race, and combined anteroapical repair (OR 1.30) were associated with increased odds of future SUI surgery.

CONCLUSION: The rate of subsequent surgery for de novo SUI following POP repair on a population level is low. Patient and surgical characteristics may alter a woman's individual risk and should be considered in surgical planning.
