For completely endophytic renal tumours, both OPN and RAPN have excellent outcomes when performed by experienced surgeons at a high-volume centre. For skilled robotic surgeons, RAPN is a safe and effective alternative to OPN with the advantages of shorter length of stay and less blood loss.

Perioperative morbidity, after partial nephrectomy, is acceptable in cT1/pT3 tumors in comparison to cT1/pT1; however, upstaged patients had a worse oncological outcome. cT1/pT3a tumors are associated with adverse clinico-pathological features. Preoperative risk predictors of upstaging were higher R.E.N.A.L. score and male gender.

At a high volume center the rate of robotic partial nephrectomy conversion to radical nephrectomy was 3.1%, including 2.2% of preoperatively anticipated nephrectomy cases. Increasing tumor size and complexity, and poor preoperative renal function are the main predictors of conversion.
