OBJECTIVE: The purpose of this study was to compare the risk of surgically treated stress urinary incontinence (SUI) and pelvic organ prolapse (POP) in relation to mode of delivery and age at first childbirth. STUDY DESIGN: This was a cohort study. Data from the Swedish Medical Birth Register on women with only cesarean delivery (n = 30,880 women) or only vaginal delivery (n = 59,585 women) were compared with the Swedish Patient Register to calculate incidence rates and hazard ratios (95% confidence interval [CI]) for SUI and POP surgery. RESULTS: In analyses that were stratified by age, vaginal delivery consistently increased the risks of SUI and POP surgery. Among vaginally delivered women who were ≥ 30 years old, incidence rates of POP surgery were 13.8 (95% CI, 12.7-15.1), and for younger women were 6.4 (95% CI, 6.0-6.8) per 10,000 person-years. Exclusion of instrumental vaginal delivery did not alter the conclusions. CONCLUSION: Increasing age at first delivery increased the risk of subsequent SUI and POP surgery after both vaginal and cesarean delivery.
