目的 探讨肾错构瘤的保留肾单位手术方法并总结临床经验。方法 对我院自2010年3月-2014年9月共12例行保肾 手术的肾错构瘤患者临床资料进行回顾性分析。结果 12例手术均获得成功，其中7例行后腹腔镜下肾错构瘤剜 除术，5例行开放肾错构瘤剜除术。手术时间75-210min，平均(122.9±39.2)min；热缺血时间15-40min，平均 (26.0±8.6)min；术中出血量30-650ml，平均(127.9±174.9)ml。术中输血1例。术后病理均证实为肾血管平滑肌 脂肪瘤。术后随访3-18个月，均无复发。结论 肾错构瘤剜除术手术效果确切，能最大限度保护肾功能，是一种安 全有效的手术方法。

Objective To discuss the methods of nephron-sparing surgery for treatment of renal hamartoma and summarize the clinical experience. Methods The clinical data of 12 cases of renal angeomyolipoma treated by nephron-sparing surgery from March 2010 to September 2014 were analyzed retrospectively. Results All prcedures were performed successfully ,7 cases were treated by retroperitoneal laparoscopic enucleation. 5cases were treated by open surgery of enucleation.Mean operation time was (122.9±39.2)min(from 75 min to 210 min), Mean warm ischemia time was (26.0±8.6)min(from 15 min to 40 min),Mean blood loss was (127.9±174.9)ml( from 30ml to 650ml).1case was received blood transfusion during the operation.All 12 cases of renal angiomyolipoma were confirmed by postoperative pathological test. None recurred during the follow-up from 3 to 18 months. Conclusions The effect of enucleation for treatment of renal hamartoma is exactly.This method can maximally protect ranal function and it is a safe and effective surgery.
