• Objectives To evaluate the safety and efficacy, and long‐term functional and oncologic outcomes of robot‐assisted partial nephrectomy in high‐complexity tumors. Methods Data of 155 patients with a high‐complexity tumor (PADUA score ≥10) were reviewed. Trifecta achievement, intra‐, perioperative, functional, and oncologic outcomes were analyzed and compared between patients with increasing complexity. Results Of the 155 patients, 65 (41.9%) patients had a PADUA score of 10, 55 (35.5%) had a PADUA score of 11, and 35 (22.6%) had a PADUA score of 12–13, respectively. The median (interquartile range) operative time, warm ischemia time and estimated blood loss were 150 min (112–186 min), 26 min (23–32 min) and 250 mL (100–500 mL), respectively. Postoperatively, complications occurred in 25 (16.1%) patients, and positive surgical margins in 15 (10.5%) patients. Trifecta was achieved in 67 (43.2%) patients. At a median follow‐up period of 58 months, the median estimated glomerular filtration rate preservation was 87% (78–110), and 12 (7.7%) patients developed new‐onset chronic kidney disease. Recurrence‐free survival and overall survival rates were 93.6% and 96.7%, respectively. Positive surgical margins were statistically different between the groups of PADUA score 10, 11 and 12–13 (P = 0.017), whereas functional and oncologic outcomes were similar. In multivariate logistic regression analysis, increasing tumor size (odds ratio 1.48, 95% confidence interval 1.21–1.87; P < 0.001) and the American Society of Anesthesiologists score 2/3 (odds ratio 0.48, 95% confidence interval 0.24–0.96; P = 0.041) were independent predictors of trifecta failure. Conclusions Robot‐assisted partial nephrectomy is a safe and effective treatment for high‐complexity tumors providing excellent long‐term functional and oncologic outcomes.
