The surgeon experience was assessed by examining perioperative outcomes among three groups of consecutive patients (first=14, second=14, third=15 patients, respectively).</p><p><strong>Results:</strong> Between February 2014 and February 2020, 45 RAPNs were performed out of a total of 200 robotic procedures. The median tumor size was 3 cm, and 28 (65%) patients had a R.E.N.A.L nephrometry score (RNS) ≥7. The median operative time and warm ischemia time (WIT) were 190 and 16 minutes, respectively. The median estimated blood loss (EBL) was 100 mL. Two (4%) patients had a positive surgical margin (PSM). Overall, five (12%) complications were recorded. All except one were minor (Clavien I–II). The median followup was 26.2 months. Trifecta and pentafecta were achieved in 40 (93%) and 27 (81.8%) patients, respectively. Increased surgeon experience was significantly associated with a shorter operative time and less EBL. Furthermore, there was an independent association between surgeon experience and operative time and EBL, and between RNS and operative time and WIT.</p><p><strong>Conclusions:</strong> With fellowship training and subsequent adequate total number of robotic procedures during practice, it is possible to perform RAPN with favorable perioperative outcomes in the setting of low-volume of cases over an extended duration.</p> ER -
