XXXX Alone Results in Urge Incontinence Rather Than in Complete @entity1241 .

BACKGROUND: Conscious external anal sphincter contraction is mediated by the pudendal nerve. @entity16 is, therefore, believed to result in @entity1241 . Until urge sensation is experienced, fecal continence is maintained by unconscious external anal sphincter contraction, which is regulated by the anal-external sphincter continence reflex. The innervation of unconscious contraction is yet unknown. OBJECTIVE: We aimed to determine whether unconscious contraction is mediated by the pudendal nerve and whether age influences unconscious contraction. DESIGN: This was a retrospective comparative study. SETTINGS: The study was conducted in a tertiary care center. @entity1 : Seventy adult @entity1 experiencing defecation problems who underwent anorectal function tests were included in this study. MAIN OUTCOME MEASURES: Conscious and unconscious contractions were compared between @entity1 with and without @entity16 . Conscious contraction was defined by maximum anal sphincter contractility, unconscious contraction by pressure in the anal canal at maximum tolerable or retainable sensation during the balloon retention test. RESULTS: Unconscious contraction did not differ significantly between @entity1 with @entity16 and @entity16 @entity1 , whereas conscious contraction was significantly lower in @entity1 with @entity16 . Multiple linear regression analyses demonstrated that unconscious contraction, in contrast to conscious contraction, was not predicted significantly by age and anal electrosensitivity at 2   cm, which represents @entity16 . @entity1 with @entity16 were significantly older than @entity1 with @entity16 . LIMITATIONS: The pudendal nerve motor latency and EMG tests were not performed. CONCLUSIONS: The pudendal nerve does not mediate unconscious external anal sphincter contraction. @entity16 alone, therefore, results in urge @entity322 rather than in complete @entity1241 . Unconscious contraction appears not to be influenced by age. Therefore, most of the elderly @entity1 experience urge @entity322 rather than complete @entity1241 .
