Abstract

71 women delivered at St Bartholomew's Hospital, London, were studied by electrophysiological tests of the innervation of the external anal sphincter muscle and by manometry. The investigations were done 2-3 days after delivery and again, in 70% of these women, 2 months later. Faecal and urinary incontinence developing after vaginal delivery has been thought to be due to direct sphincter division, or muscle stretching, but the results of the study suggest that in most cases this incontinence results from damage to the innervation of the pelvic floor muscles.

摘要

对伦敦圣巴塞洛缪医院分娩的71名女性进行了研究,通过对肛门外括约肌神经支配的电生理测试和测压法进行研究。这些调查在分娩后2至3天进行,并且在其中70%的女性中,两个月后再次进行。阴道分娩后出现的粪便和尿液失禁一直被认为是由于括约肌直接撕裂或肌肉拉伸所致,但研究结果表明,在大多数情况下,这种失禁是由盆底肌肉神经支配受损引起的。
