We present the oncological and functional results from a series of 43 patients with renal tumours, treated consecutively with robot-assisted partial nephrectomy (RPN). Between 2010 and 2014, we performed 95 RPNs. To assess the results, we included only those patients (n=43) who had a minimum follow-up of 2 years. A descriptive analysis was conducted of the demographic characteristics and perioperative variables. We employed Kaplan-Meier curves to assess overall survival, cancer-specific survival and recurrence-free survival. The patients' mean age was 53.1±13.5 years. The mean preoperative tumour size was 3.7±2.3cm. The mean surgical time was 102.2±37.1min. The mean ischemia time was 21.27±7.74minutes, with a median intraoperative bleeding volume of 150mL (IQR, 87.5-425). There was a 7% rate of postoperative complications (Clavien≥III). There was no mortality. The average Fürhman grade was 2.5±0.56. There were no positive surgical margins or local recurrences. The median follow-up was 38±8 months, with an overal survival, recurrence-free survival and cancer-specific survival of 100% at 3 years of follow-up. The recurrence-free survival was 92,3% at 48 months of follow-up. The mean preoperative glomerular filtration rate was 91.04±28.17mL/min/1.73m(2), and the postoperative rate was 89.9±27.69mL/min/1.73m(2), with a nonsignificant reduction (P=.74). The functional and oncological results of our series confirm the safety and efficacy of RPN. RPN offers optimal preservation of renal function and oncological control in the medium term.
