Robot-assisted partial nephrectomy in complex renal tumors using the Versius platform: An initial but promising...

Area of Science:

• Urology
• Robotic Surgery
• Nephrology

Background:

• Robotic surgery is increasingly used in urology, prompting exploration of robot-assisted partial nephrectomy (RAPN).
• The CMR Versius system's application in RAPN for complex renal masses remains under-explored.

Purpose of the Study:

• To evaluate the initial experience of performing RAPN for complex renal masses using the CMR Versius platform.
• To assess the feasibility and outcomes of this novel approach.

Main Methods:

• A prospective study of 30 patients with complex renal masses undergoing RAPN with the CMR Versius system.
• Tumor complexity was assessed using the preoperative aspects of the dimension used for anatomic (PADUA) nephrometry scores.
• Key outcomes included surgical margins, warm ischemia time (WIT), and complications (Clavien-Dindo II).

Main Results:

• All 30 cases were completed successfully without conversion to open or laparoscopic surgery.
• The mean WIT was 26.67 minutes, and surgical margins were free in all patients.
• The 'TRIFECTA' outcome (free margins, WIT < 30 min, no major complications) was achieved in 83.33% of patients.

Conclusions:

• RAPN with the CMR Versius platform is a feasible option for complex renal masses.
• This approach may involve slightly increased but acceptable warm ischemia time and operative time.
• Successful implementation requires a highly experienced surgical team.
