Simplified robot-assisted partial nephrectomy: step-by-step technique and perioperative outcomes

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robot-assisted partial nephrectomy (RAPN) has technical aspects with ongoing debate.
• A standardized, simplified RAPN technique is needed for broader adoption and training.

Purpose of the Study:

• To present a simplified, step-by-step technique for robot-assisted partial nephrectomy (RAPN).
• To report the perioperative outcomes of a single-center series using this simplified RAPN technique.

Main Methods:

• A 12-step simplified RAPN technique was developed and standardized over 7 years.
• Prospective collection of patient characteristics and perioperative outcomes for 406 patients undergoing RAPN.
• Key steps include transperitoneal approach, minimal mobilization, ureter identification, early unclamping, and no drains/agents.

Main Results:

• Mean warm ischemia time was 15.3 minutes.
• Conversion rates to open surgery and radical nephrectomy were 3.5% and 5.2%, respectively.
• Post-operative complications occurred in 32.5% of patients (11.6% major), with a positive surgical margin rate of 5.6%.

Conclusions:

• The simplified RAPN technique is feasible and reproducible.
• Satisfactory perioperative outcomes were achieved with this simplified approach.
• The technique is suitable for surgeons with varying experience levels, facilitating easier learning.
