Changes in connective tissue during pregnancy, pressure and weight of the uterus on the pelvic floor, weight gain of the mother, trauma to the pelvic
floor during vaginal delivery, abdominal straining during labor and ensuing nerve damage all promote prolapse.
Urinary incontinence (UI) has an effect on quality of life
during the postpartum period.1, 2 Fear of UI is one of the most common reasons for maternal demand for cesarean
delivery.3, 4 The muscle strength of the pelvic
floor returns to the antepartum value 6 — 10 weeks postpartum in most women.5, 6 However, UI symptoms after
delivery do not resolve in the long term in some women.7, 8 Studies have variously concluded that the prevalence of UI changed9 or did not change within 6 months or 1 year postpartum.10, 11 A higher prevalence or incidence of UI has been observed in women who had a
vaginal delivery than in women who underwent cesarean
delivery.10 — 18 In contrast, a recent study found that
vaginal delivery was not associated with postpartum UI.19 The long - term protective effect of cesarean
delivery has not been determined.20 Validated and reliable questionnaires to evaluate UI, including severity and quality of life, are needed for postpartum evaluation.21 However, comparisons of UI severity and the effect on daily life between women who have had
vaginal and cesarean
deliveries are scarce.22
