ABSTRACT

Objective: The aim of this study was to identify obstetric and maternal risk factors for stress urinary incontinence and anal incontinence after an obstetric event. Methods: 720 women were evaluated six weeks after the obstetric event. The cases of urinary incontinence were defined as those women who had urine leak during stress. The cases of anal incontinence were defined as those women who had an involuntary passing of gas, liquid or solid feces or fecal staining. The controls for urinary and anal incontinence were defined as those that did not show all these symptoms before or during pregnancy. We reviewed the following characteristics: maternal age, gestational age, newborn birth weight, parity, type of delivery, presence of third degree tear, episiotomy, duration of the second stage of labor. Results: The frequency of stress urinary incontinence was 15.6% and anal incontinence was 8.3%. The newborn weighing 4 kg increases the risk of stress urinary incontinence (odds ratio, 1.2; CI 95%, 1.1-1.2); however, after adjusting, we find a not significant association (odds ratio, 2.6; CI 95%, 0.9-7.2). Third degree perineal tear increased the risk of anal incontinence (adjusted odds ratio, 7.9; CI 95%, 2.3-26.7). Cesarean section became a protecting factor both for urinary incontinence (odds ratio, 0.4; CI 95%, 0.2-0.8), as well as for anal incontinence (odds ratio, 0.1; CI 95%, 0.05-0.6). Conclusions: Urinary and anal incontinence are often present after the obstetric event and there is an association between anal sphincter injury during delivery and the development of anal incontinence. Cesarean section is a protective factor for both.
