Summary
Laparoscopic partial nephrectomy (LPN) and laparoscopic cryoablation (LCA) are effective for multiple kidney tumors. Both minimally invasive options offer similar outcomes for renal function, complications, and survival in select patients.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Nephrology
Background:
- Managing multiple ipsilateral renal tumors presents a clinical challenge.
- The efficacy of minimally invasive nephron-sparing procedures for these cases remains under-assessed.
Purpose of the Study:
- To assess the feasibility and outcomes of laparoscopic partial nephrectomy (LPN) versus laparoscopic cryoablation (LCA).
- To compare LPN and LCA in patients with multiple ipsilateral renal tumors.
Main Methods:
- Retrospective review of 27 patients with synchronous multiple ipsilateral renal tumors.
- Patients underwent either LPN (14 patients, 28 tumors) or LCA (13 patients, 31 tumors) as the sole treatment.
- Data on demographics, intraoperative, postoperative, and follow-up parameters were compared.
Main Results:
- LPN group had fewer tumors and larger dominant tumor size but greater blood loss and longer hospital stays.
- No open conversions or kidney loss occurred in either group.
- Complication rates, renal function, and intermediate-term cancer-specific survival were similar between LPN and LCA.
Conclusions:
- Both LPN and LCA are viable minimally invasive options for select patients with multiple ipsilateral renal tumors.
- Comparable renal functional outcomes, complication rates, and survival suggest suitability of both techniques.
