Multiple synchronous renal tumors (MSRT) in unilateral kidney are clinically rare. Simultaneous resection for multiple tumors with RAPN is complicated and challenging. Herein, we report the successful resection of three synchronous renal tumors located in unilateral kidney with RAPN using the hinotori surgical robot system.
A 75-year-old man was diagnosed with multiple left renal tumors (45 mm and 20 mm in diameter) that presented very close to each other. We performed RAPN using hinotori and excised the tumors simultaneously. Postoperative renal function was maintained. No complications were identified. The three histological types were distinct: ccRCC, pRCC, and small renal angiomyolipoma.
To the best of our knowledge, this is the first report of MSRT in unilateral kidney successfully treated with RAPN using hinotori.
单侧肾脏的多发同步性肾肿瘤（MSRT）在临床上较为罕见。使用机器人辅助腹腔镜肾部分切除术（RAPN）同时切除多个肿瘤复杂且具有挑战性。在此，我们报告使用火鸟手术机器人系统通过RAPN成功切除位于单侧肾脏的三个同步性肾肿瘤。
一名75岁男性被诊断为左肾多发肿瘤（直径分别为45毫米和20毫米），这些肿瘤彼此位置非常接近。我们使用火鸟进行了RAPN，并同时切除了肿瘤。术后肾功能得以维持。未发现并发症。三种组织学类型各不相同：透明细胞肾细胞癌（ccRCC）、乳头状肾细胞癌（pRCC）和小肾血管平滑肌脂肪瘤。
据我们所知，这是首例使用火鸟通过RAPN成功治疗单侧肾脏MSRT的报告。
