Summary
Laparoscopic partial nephrectomy (LPN) is safe for multiple kidney tumors. A tailored approach without clamping reduced operative time and hospital stay, with no cancer recurrence in selected patients.
Area of Science:
- Urology
- Surgical Oncology
Background:
- Laparoscopic partial nephrectomy (LPN) is established for solitary renal masses.
- Its use for multiple ipsilateral renal tumors is less documented.
Purpose of the Study:
- To review the experience with LPN for multiple ipsilateral renal tumors.
- To assess the safety and efficacy of LPN in this context.
Main Methods:
- Retrospective review of seven patients with multiple ipsilateral renal tumors treated with LPN.
- Comparison between LPN performed with and without hilar clamping.
Main Results:
- 16 tumors (mean size 2.1 cm) were resected; 9 were renal cell carcinoma.
- The no-clamp group had shorter operative time and hospital stay compared to the clamp-suture group.
- No local recurrence or metastasis observed in cancer patients after 48 months follow-up.
Conclusions:
- LPN is a safe and effective option for selected patients with multiple ipsilateral renal tumors.
- A tailored approach, potentially avoiding renal ischemia, can optimize outcomes.
