An electrophysiologic technique to evaluate the anatomic integrity of the peripheral pathways to the bladder and sphincters is described. Evoked electromyographic responses of the anal sphincter are produced by stimulating the bladder wall and urethra. Impulses travel via the pelvic nerves and cauda equina to the conus medullaris, activating the pudendal nerve nucleus and resulting in contraction of the external anal sphincter. Lesions along this pathway produce either prolonged latencies and depressed responses or complete loss of response. Correlation of the results of this technique in 110 patients with clinical myelographic and operative findings indicates that the technique is a useful clinical tool.
描述了一种评估膀胱和括约肌外周通路解剖完整性的电生理技术。通过刺激膀胱壁和尿道产生肛门括约肌的诱发肌电图反应。冲动经盆腔神经和马尾神经传至脊髓圆锥，激活阴部神经核，导致肛门外括约肌收缩。该通路的损伤会导致潜伏期延长和反应减弱或反应完全丧失。对110例患者的该技术结果与临床脊髓造影和手术结果进行的相关性分析表明，该技术是一种有用的临床工具。
