Does the severity of spontaneous genital tract trauma affect postpartum pelvic floor function?

We describe the impact of genital trauma on pelvic floor function in a low-risk cohort of women after vaginal birth. Questionnaires (Present Pain Intensity Scale, Incontinence Impact Questionnaire, Fecal Incontinence Score, and Intimate Relationship Scale) were completed up to 12 weeks postpartum. Severity of trauma was recorded at delivery. Overall follow-up was 444/565 (79%). Major trauma (trauma that involved perineal muscles or required suturing) occurred in 20%; 20% delivered intact. At 12 weeks, 10% complained of perineal pain; 24% reported anal (AI) and 27% urinary incontinence (UI). Women with trauma were no more likely than those intact to complain of UI or AI, sexual inactivity, or perineal pain postpartum (all P=NS). Women with major trauma had weaker pelvic floor exercise strength than those who delivered intact or with minor trauma (odds ration 3.06, 95% confidence interval 1.41-6.63). Pelvic floor complaints postpartum were common but not associated with severity of genital trauma in a cohort of low-risk women.
