The median age of the patients was 59 years. The mean histological size of tumor was 32.2\u2009mm (IQR 23.8\u201340). The median total surgical time was 130 minutes (IQR 110\u2013176) with a median warm ischemia time of 22.0 minutes. The tumor was located anteriorly in 25% of the cases. The median R.E.N.A.L.* nephrometry score was 6. The median estimated blood loss was 30\u2009mL (IQR 10\u201380). Three cases were converted to open partial nephrectomy because of bleeding (2.7%). Four patients and one patient returned within 30 days with postoperative complications Clavien-Dindo classification grade 2 and 3a, respectively. Two patients needed perioperative blood transfusion because of bleeding.
