Introduction:
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.
Case Presentation:
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.
Conclusion:
To the best of our knowledge, this is the first report of MSRT in unilateral kidney successfully treated with RAPN using hinotori.
