PUDENDAL NERVE DAMAGE INCREASES THE RISK OF FECAL INCONTINENCE IN WOMEN WITH ANAL SPHINCTER RUPTURE AFTER CHILDBIRTH

Aim. To evaluate anal function after childbirth in 94 women in whom sphincter rupture occurred and in 19 control women. The findings of anorectal physiological assessment and history of childbirth were related to the presence of fecal incontinence. Methods. Anal manometry and electromyography were performed the first days after childbirth and repeated 3 months post partum together with measurement of pudendal nerve terminal motor latency.Results. Eighteen patients (19%) presented with incontinence. None of the controls developed fecal incontinence after delivery. Anal manometry showed that both incontinent and continent patients had decreased resting and squeeze pressures compared to control subjects (p 2.0 millis...
