Robot-Assisted Partial Nephrectomy for Multiple Synchronous Renal Tumors in Unilateral Kidney Using Hinotori Surgical...

Area of Science:

• Urology
• Surgical Oncology
• Robotic Surgery

Background:

• Multiple synchronous renal tumors (MSRT) in a unilateral kidney are rare and pose surgical challenges.
• Robotic-assisted partial nephrectomy (RAPN) offers minimally invasive options for renal tumor resection.
• Simultaneous resection of multiple tumors via RAPN requires advanced surgical skill and planning.

Purpose of the Study:

• To report the successful application of the hinotori surgical robot system for RAPN in a patient with MSRT.
• To demonstrate the feasibility and safety of simultaneous resection of multiple renal tumors using this robotic platform.
• To highlight the potential of hinotori in managing complex renal tumor cases.

Main Methods:

• A 75-year-old male patient with three distinct synchronous renal tumors in the left kidney underwent RAPN.
• The hinotori surgical robot system was utilized for precise tumor excision.
• Simultaneous resection of all three tumors was performed, followed by assessment of renal function and complications.

Main Results:

• Successful simultaneous resection of three synchronous renal tumors (45mm, 20mm, and angiomyolipoma) was achieved using the hinotori system.
• Postoperative renal function was well-maintained.
• No intraoperative or postoperative complications were observed.

Conclusions:

• This case represents the first documented instance of MSRT in a unilateral kidney successfully treated with RAPN using the hinotori surgical robot.
• The hinotori system facilitates complex RAPN procedures, including simultaneous resection of multiple tumors.
• This approach shows promise for preserving renal function in patients with multiple renal tumors.
