AIMS: To analyze the effect of one interval vaginal delivery on the prevalence of stress @entity322 amongst a cohort of nulliparous @entity1 . METHODS: A cohort of 276 nulliparous @entity1 without @entity322 was recruited consecutively in 1996, after they had vaginal delivery, and were followed-up for @entity322 in 2000. The age, obstetric variables of the 1996 delivery (mode of delivery, genital tract @entity130 , birth weight, @entity1337 , episiotomy, durations of labor, postpartum urinary retention), and the presence of interval vaginal delivery during the follow-up period were recorded. The obstetric factors and the prevalence of @entity3142 at follow-up were then compared between @entity1 with and without interval vaginal delivery. Logistic regression analysis was performed to test the independence of the obstetric variables in the index pregnancy and the presence of one interval vaginal delivery, with @entity3142 being the dependent variable. RESULTS: A total of 148 (53.6%) @entity1 were followed-up. The prevalence of @entity322 was 28.6% in @entity1 without interval delivery and 21.1% in @entity1 with one interval delivery. There was no significant difference in the prevalence of @entity322 between the two groups (chi(2) test, P = 0.31). Logistic regression showed that none of the obstetric variables or the presence of one interval vaginal delivery was significantly associated with @entity322 . CONCLUSIONS: One interval vaginal delivery does not increase risk of @entity3142 4 years after the index vaginal delivery.
