2μm激光在肾癌保留肾单位手术中的临床应用(附5例报告)

Clinical applications of 2-micron continuous wave laser in nephron sparing surgery for renal cell carcinoma(report of 5 cases)

目的探讨2μm激光在肾癌保留肾单位手术中的临床应用效果。方法经腰开放手术下使用功率50W的2μm激光对5例无症状肾癌患者行保留肾单位的肾肿瘤切除术,患者均为男性,平均年龄47岁,均为单侧,左侧4例,右侧1例。结果5例患者均手术成功,手术时间105～120min,平均110min,术中出血80～400ml,均未输血,未出现术中集合系统损伤、术后尿瘘、术后出血及急性肾功能不全等并发症,肾周引流管留置时间4～5d。术后病理示5例患者均为肾脏透明细胞癌。结论2μm激光用于肾癌保留肾单位手术止血效果佳,出血少,切除完整,是对肾癌保留肾单位手术方式的新的探索。

Objective To review our initial experience with 2-micron continuous wave laser in nephron-sparing surgery for renal cell carcinoma. Methods Clinical data of 5 patients with kidney neoplasms who received nephron-sparing surgery with 2-micron continuous wave laser were reviewed retrospectively. Results Operations were performed successfully on 5 patients （mean operation time 110 min, ranged 105-120 rain）. The mean volume of blood loss was 200 ml, ranged 80-400 ml. Conclusions 2-micron conclusions wave laser assisted nephron-sparing surgery is a new explora- tion on the treatment of renal cell carcinoma.
