为了提高直肠癌的治疗效果,不仅行上方淋巴结的扩清、而且还强调进行侧方淋巴结的扩清,其疗效已被多数学者所承认。但术后排尿及性功能障碍,几乎是不可避免的,原因是术中损伤了植物神经。从84年至今我们行保留植物神经的直肠癌根治术70例,本文就不同程度保留植物神经的术式,研究其对排尿及性功能的影响。 In order to improve the therapeutic effect of rectal cancer, not only the expansion of the upper lymph nodes, but also emphasize the expansion of lateral lymph nodes, its efficacy has been recognized by most scholars. However, postoperative urination and sexual dysfunction are almost unavoidable due to the damage to the autonomic nerve during surgery. We have preserved 70 cases of rectal cancer resection of autonomic nerves from 84 years ago. This article has preserved the autonomic nerves in different degrees and studied its effect on urination and sexual function.
