Recently, robot-assisted laparoscopic partial nephrectomy (RAPN) has become a commonly performed surgical treatment for small renal tumors, but for difficult cases, such as those presenting with multiple tumors, there are few institutions with experience. We herein report two cases of unilateral multifocal renal cell carcinoma that were successfully treated with RAPN. Case 1: A 65-year-oldwoman was incidentally identified to have two right kidney tumors on imaging. RAPN under cold ischemia was performed. Pathological examinations revealed both tumors to be clear cell carcinoma. Case 2: A 56-year-oldman was incidentally found to have two left kidney tumors on imaging. RAPN under zero-ischemia and warm ischemia was performed. Pathological examinations revealed both tumors to be clear cell carcinoma. In both cases, no recurrence has been observed, and the decrease that occurred in the renal function was mild during the one-and-a half year follow-up.
最近，机器人辅助腹腔镜肾部分切除术（RAPN）已成为治疗小肾肿瘤的常用手术方法，但对于复杂病例，如存在多个肿瘤的病例，有经验的机构较少。我们在此报告两例经RAPN成功治疗的单侧多灶性肾细胞癌病例。病例1：一名65岁女性在影像学检查中偶然发现右肾有两个肿瘤。在冷缺血下行RAPN。病理检查显示两个肿瘤均为透明细胞癌。病例2：一名56岁男性在影像学检查中偶然发现左肾有两个肿瘤。在零缺血和温缺血下行RAPN。病理检查显示两个肿瘤均为透明细胞癌。在这两个病例中，均未观察到复发，且在一年半的随访期间肾功能仅有轻度下降。
