Summary
Laparoscopic partial nephrectomy (LPN) is feasible for large renal tumors (>4 cm) with acceptable outcomes. However, increased warm ischemia time and complication rates warrant further investigation for this complex procedure.
Area of Science:
- Urology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Partial nephrectomy is the standard for small renal masses.
- The safety and efficacy of laparoscopic partial nephrectomy (LPN) for large renal masses (>4 cm) remain under investigation.
Purpose of the Study:
- To evaluate the perioperative safety and pathological outcomes of LPN for large renal masses (>4 cm).
Main Methods:
- A retrospective review of 100 patients undergoing LPN for renal masses.
- Patients were stratified into two groups: ≤4 cm (Group A, n=67) and >4 cm (Group B, n=33).
- Demographic, perioperative, and pathological data were analyzed.
Main Results:
- Group B tumors were larger (5 cm vs 2.4 cm) and more complex, requiring more transperitoneal approaches and pelvicalyceal repairs.
- Complication rates were higher in Group B (27.2% vs 13.4%), though not statistically significant (P=0.09).
- Postoperative estimated glomerular filtration rate was significantly lower in Group B (P=0.004), while carcinoma and positive surgical margin rates were comparable.
Conclusions:
- LPN for large renal tumors (>4 cm) is feasible with acceptable pathological results.
- The increased warm ischemia time and complication rates in larger tumors require further study.
- The role of LPN in managing large renal masses needs additional research.
