Relation between perineal descent and pudendal nerve damage in idiopathic faecal incontinence.
In 60 patients with idiopathic anorectal incontinence, without neurological disease, there was a significant relationship, shown by regression analysis, between the pudendal nerve terminal motor latency and the extent of perineal descent during straining (r 0.59; p less than 0.001), and the plane of the perineum on straining (r -0.61; p less than 0.001). These data are consistent with the suggestion that perineal descent can lead to stretch-induced damage to the perineal nerves in this condition.
