Summary
Robotic partial nephrectomy (RPN) is safe and effective for complex renal masses (R.E.N.A.L. Nephrometry Score ≥10). Experienced surgeons achieve high trifecta rates, with age and eGFR impacting outcomes.
Area of Science:
- Urology
- Surgical Oncology
- Robotic Surgery
Background:
- Complex renal masses present surgical challenges for robotic partial nephrectomy (RPN).
- Increasing use of RPN for small renal masses necessitates evaluation for complex cases.
Purpose of the Study:
- To assess the safety, feasibility, and outcomes of RPN for complex renal masses (R.E.N.A.L. Nephrometry Score ≥10).
- To determine trifecta achievement rates in a multi-institutional cohort.
Main Methods:
- Retrospective analysis of 372 patients undergoing RPN for complex renal masses (R.E.N.A.L. Nephrometry Score ≥10).
- Primary endpoint: trifecta achievement (negative margin, no major complications, warm ischemia time ≤25 min).
- Statistical analysis included chi-square, Fisher exact, Mann-Whitney U, Kruskal Wallis, and logistic regression.
Main Results:
- Overall trifecta achievement was 72.04% in 372 patients.
- No significant differences in trifecta rates, operative time, or complications were observed across R.E.N.A.L. scores.
- Older age and lower baseline eGFR were independently associated with lower trifecta achievement.
Conclusions:
- RPN is a safe and reproducible option for complex renal tumors (R.E.N.A.L. Nephrometry Score ≥10).
- Experienced surgeons achieve excellent short-term outcomes.
- Further long-term oncological and functional data are warranted.
