目的探讨后腹腔镜下肾部分切除术治疗早期肾肿瘤的临床疗效。方法选择我院早期肾肿瘤患者30例,对其采取后腹腔镜下肾部分切除术。结果本组均成功进行手术,未发生转开放手术情况。平均手术时间36.8±30.5min。其中28例只阻断肾动脉,热缺血时间24-43min;2例位于肾下极背侧的肿瘤患者未阻断肾蒂。术中平均出血量120.2±45.6ml。平均住院时间1.8±4.5d。本组患者均未出现漏尿、出血等并发症。经病理检查显示肾透明细胞癌25例,肾血管平滑肌脂肪瘤5例,切缘均呈阴性。随访6-12个月,30例患者的肾功能均正常,未见肿瘤复发及转移迹象。结论后腹腔镜肾部分切除术治疗早期肾肿瘤效果确切,具有住院时间短、创伤小、恢复快等优点,保障了患者的就医质量。 Objective To investigate the clinical effect of retroperitoneal partial nephrectomy in the treatment of early renal tumors. Methods Thirty patients with early renal tumors in our hospital were selected and underwent laparoscopic partial nephrectomy. Results All the patients in this group were successfully operated and did not switch to open surgery. The average operation time was 36.8 ± 30.5min. Among them, 28 cases only blocked the renal artery, and the warm ischemic time was 24-43 minutes. Two patients with tumors located in the dorsal ramus did not block the renal pedicle. Intraoperative blood loss was 120.2 ± 45.6ml. The average length of stay 1.8 ± 4.5d. The patients did not appear leakage of urine, bleeding and other complications. The pathological examination showed 25 cases of clear cell renal cell carcinoma, 5 cases of renal angiomyolipoma, margin was negative. All cases were followed up for 6-12 months. The renal function of the 30 patients was normal. No signs of tumor recurrence and metastasis were observed. Conclusions Retroperitoneal laparoscopic partial nephrectomy for the treatment of early renal tumors is effective and has the advantages of shorter hospital stay, less trauma and faster recovery, which ensures the quality of medical care of patients.
