Summary
This study introduces a novel zero-ischaemia robotic partial nephrectomy (RPN) technique for complex hilar tumours, demonstrating its safety and feasibility. The clamp-free approach successfully preserved renal function without compromising oncological outcomes.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Robotic partial nephrectomy (RPN) is a minimally invasive option for kidney tumours.
- Concerns exist regarding prolonged ischaemia time and outcomes for complex hilar tumours.
- A novel zero-ischaemia RPN technique aims to address these challenges.
Purpose of the Study:
- To detail the technique of zero-ischaemia RPN for complex hilar tumours.
- To present initial perioperative outcomes of this novel approach.
- To evaluate the safety and feasibility of clamp-free RPN for challenging renal masses.
Main Methods:
- A prospective database of over 100 patients undergoing minimally invasive zero-ischaemia PN was reviewed.
- Seven patients with hilar tumours who underwent robotic partial nephrectomy (RPN) were selected.
- The zero-ischaemia RPN technique was meticulously detailed, and perioperative outcomes were recorded.
Main Results:
- Zero-ischaemia RPN was successfully performed in all seven cases without hilar clamping.
- Median tumour size was 4.1 cm with a median RENAL score of 10, indicating complexity.
- No intraoperative complications occurred; postoperative complications were minor (Clavien I-II).
- All specimens had negative surgical margins, and no patient experienced kidney loss or significant renal function decline.
Conclusions:
- Zero-ischaemia robotic partial nephrectomy (RPN) is a safe and feasible technique for complex hilar tumours.
- Eliminating warm ischaemia during RPN may optimize renal function preservation.
- Further randomized studies are warranted to confirm the renal functional benefits of clamp-free RPN.
