Robotic and laparoscopic partial nephrectomy: a matched-pair comparison from a high-volume centre

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Partial nephrectomy (PN) is a standard treatment for kidney tumors.
• Robotically assisted partial nephrectomy (RPN) and laparoscopic partial nephrectomy (LPN) are minimally invasive techniques.
• Direct comparison of RPN and LPN outcomes is limited.

Purpose of the Study:

• To compare the outcomes of robotically assisted partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN).
• To evaluate the relative merits of RPN and LPN in a matched-pair analysis.

Main Methods:

• A retrospective matched-pair analysis of 12 patients undergoing RPN versus 12 patients undergoing LPN.
• Patients were matched based on age, gender, BMI, ASA score, tumor characteristics, and unclamping technique.
• Outcomes assessed included operative time, blood loss, warm ischemia time (WIT), renal function, complications, and surgical margins.

Main Results:

• No significant differences were observed in perioperative variables, renal function, transfusion rates, or complication rates between RPN and LPN.
• Laparoscopic PN required fewer ports compared to RPN.
• A subset analysis indicated a shorter warm ischemia time (WIT) with LPN during early unclamping.

Conclusions:

• Robotically assisted partial nephrectomy (RPN) is a technically feasible and safe procedure.
• RPN is associated with a longer warm ischemia time (WIT) compared to LPN.
• Further studies and experience are needed to fully establish the comparative advantages of RPN.
