Preliminary Experience of Partial Nephrectomy Through a New Single-Port Surgical Robot System

Area of Science:

• Urology
• Surgical Technology
• Robotics in Medicine

Background:

• Partial nephrectomy (PN) is the standard treatment for T1a renal tumors.
• Minimally invasive surgical techniques are continually evolving to improve patient outcomes.
• Single-port (SP) robotic surgery offers potential advantages in reducing invasiveness.

Purpose of the Study:

• To evaluate the preliminary safety and efficacy of the Shurui SP surgical robot system.
• To assess the feasibility of using the Shurui SP robot for partial nephrectomy (PN).
• To analyze operative outcomes and perioperative data in patients undergoing robotic PN.

Main Methods:

• Prospective enrollment of 13 patients with T1a renal tumors from February to July 2022.
• Data collection included operative outcomes, perioperative data, clinical, and histological information.
• Analysis of metrics such as warm ischemia time, docking time, operation time, and NASA-TLX scores.

Main Results:

• All 13 operations were completed successfully using the Shurui SP robot without conversion to open surgery.
• Average warm ischemia time was 26.2 minutes, with no device-related adverse events reported.
• All patients achieved negative tumor margins, and no Clavien grade ≥3 complications occurred during follow-up.

Conclusions:

• The Shurui SP surgical robot system is safe and effective for partial nephrectomy.
• The system demonstrated flexibility and stability during robotic-assisted partial nephrectomy.
• Further studies are warranted to confirm these preliminary findings in a larger patient population.
