The objective of this study was to introduce the nerve plane-sparing radical hysterectomy technique and compare its efficacy and safety with that of nerve-sparing radical hysterectomy. Methods From September 2006 to August 2010, 73 consecutive patients with International Federation of Gynecology and Obstetrics stage IB to IIA cervical cancer underwent radical hysterectomy with two different nerve-sparing approaches. Nerve-sparing radical hysterectomy was performed for the first 16 patients （nerve-sparing radical hysterectomy group）. The detailed autenomic nerve structures were identified and separated by meticulous dissection during this procedure. After January 2008, the nerve plane-sparing radical hysterectomy procedure was developed and performed for the next 57 patients （nerve plane-sparing radical hysterectomy group）. During this modified procedure, the nerve plane （meso-ureter and its extens;ion） containing most of the autonomic nerve structures was integrally preserved. The patients＇ clinicopathologic characteristics, surgical parameters, and outcomes of postoperative bladder function were compared between the two groups. Results There were no significant differences between the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups regarding age, International Federation of Gynecology and Obstetrics stage, pathological type, preoperative treatment, or need for intraoperative blood transfusion. The nerve plane-sparing radical hysterectomy group had a higher body mass index than that of the nerve-sparing radical hysterectomy group （P=0.028）. The mean surgical duration in the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups were （262_＋46） minutes and （341＋36） minutes （P 〈0.01）.展开更多
