A Retrospective Study Analyzing the Incidence of Urine Incontinence after Cesarean Section Delivery in Comparison with Vaginal Delivery

Abstract

Introduction: Urine incontinence is the involuntary leakage of urine. Its actual prevalence is underestimated. There is a general belief that vaginal delivery is a major risk. Elective cesarean delivery is increasing worldwide; one reason is to protect against pelvic floor disorders, including urine incontinence. Previous studies included small samples with controversial results. This study aimed to compare the risk of urine incontinence in women who had cesarean delivery with those who had vaginal delivery. Methods: It was a retrospective study on 1751 women delivered in a university hospital over a 5- year period. Data collected on number of deliveries, age at first and last delivery, mode of each delivery, gestational age, birth weight, indication of cesarean section, induction of labor, episiotomy, perineal tears, smoking, chronic cough, chronic constipation, presence and severity of urine incontinence using ICIQ score. Patients were categorized into 2 groups: all cesarean section deliveries and at least one vaginal delivery. Results: A total of 600 respondents delivered only by cesarean section, and 1151 had at least one vaginal delivery. Urine incontinence prevalence in the cesarean group was 5.8%, and 6.9% in the vaginal group. Age, perineal tear, chronic cough, and chronic constipation were found to be significantly associated with urinary incontinence. After adjusting for all other variables, vaginal delivery was not found to be significantly associated with incontinence compared to cesarean. Conclusion: Vaginal and cesarean deliveries have a comparable incidence of urinary incontinence. It is difficult to get a firm conclusion on whether cesarean is protective. Chronic constipation and cough are important factors regardless of delivery mode.
