Urethral function following radical hysterectomy was studied by chronologic analysis of the urethral pressure profile. Thirty patients who had radical hysterectomy were divided into 2 groups according to the degree of preservation of the plexus pelvicus at operation. The method of complete preservation is described. Urethral pressure profiles showed a significant postoperative decrease of mean maximum urethral closure pressure in the group of 20 patients with bilateral nerve transection; this was not found in the group of 10 patients with complete preservation of the plexus pelvicus. The decrease was ascribed to possible damage of sympathetic nerves originating from the hypogastric nerve. The results indicated that postoperative abnormalities in urination are caused by damage not only to the parasympathetic nerves (the pelvis nerve) but to the sympathetic nerves (the hypogastric nerve) as well.
通过对尿道压力曲线进行时间分析，研究了根治性子宫切除术后的尿道功能。30例行根治性子宫切除术的患者根据术中盆腔神经丛的保留程度分为2组。描述了完全保留的方法。尿道压力曲线显示，20例双侧神经切断患者组术后平均最大尿道闭合压显著降低；而10例盆腔神经丛完全保留的患者组未发现这种情况。这种降低归因于发自腹下神经的交感神经可能受损。结果表明，术后排尿异常不仅是由副交感神经（盆神经）受损引起的，也是由交感神经（腹下神经）受损引起的。
