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 investigate the clinical effect of 2μm laser in renal cell nephron surgery. Methods Five patients with asymptomatic renal cell carcinoma undergoing open surgery under the condition of 50W 2μm laser were treated with nephron excision. The patients were all male, with a mean age of 47 years. All were unilateral and 4 on the left, Right in 1 case. Results All the 5 patients were operated successfully. The operation time was 105 ~ 120min, average 110min, intraoperative bleeding 80 ~ 400ml, no blood transfusion, no intraoperative collection system injury, postoperative urinary fistula, postoperative bleeding and acute renal insufficiency Symptoms, renal drainage tube indwelling time 4 ~ 5d. Postoperative pathology showed that 5 patients were renal clear cell carcinoma. Conclusion 2μm laser for renal cell nephron surgery to retain the hemostatic effect, less bleeding, complete resection, renal cell nephron surgery is to retain a new way of exploration.
