Description:Open in a separate window The pudendal nerve plays a critical role in maintenance of integrity and function of the anal sphincter. Neurologic compromise of the anal sphincter complex can result in incontinence and is classified as primary idiopathic or secondary. Idiopathic causes are usually a result of pudendal neuropathy resulting from repeated stretch forces exerted on the terminal portion of the pudendal nerve, due to rectal prolapse, descending perineum syndrome, multiple vaginal deliveries, or habitual straining at defecation. Stool consistency is another important etiologic factor in anal incontinence that must be considered. Incontinence to diarrhea may be a result of rapid transit of liquid stool to the rectum, which overloads the normal continence mechanisms that include capacity of the rectum, pelvic floor muscles, and anal sphincter complex.
