Introduction & Objective :

The rate of benign lesions at pathologic examination after partial nephrectomy is around 25 %,  so that it is preferred to do a conservative treatment even for large renal mass when technically feasible. We reported perioperative, functional and survival outcomes  of robotic partial nephrectomy for benign lesions larger than 7 cm.

Methods :

From a prospective multicentric data base, out of 309 patients, 38  received robotic partial nephrectomy (RPN) for renal masses larger than 7 cm with benign features at pathologic examination. Perioperative results, complication rates and functional results were collected and reported.

Results :

From April 2011 to July 2017, 38 patients, 25 females and 13 males,  received RPN for lesions larger than 7 cm with benign histology. Median age was 54 years (IQR 43-65), median preoperative hemoglobin and eGFR were 13.5 g/dl (IQR 12.75-14.5) and 89 (IQR 77-99) ml/min respectively. Median lesion size was 82 ( IQR 75-100) mm.  RPN was performed clampless in 17 cases (44.7%) and median operative time was 145 (122.5-208) minutes. Median Ischemia time was 22 (IQR 15.5-25.75) minutes. Overall complication rate was 26.3%, while high grade complication rate was 7.8 %. Median postoperative hemoglobin and eGFR were 11 (IQR 9.4-11.8) g/dl  and  80 (IQR 67-90.1) ml/min, respectively. At a median follow up of 23 months no patient developed recurrences and overall survival was rate 100%; median eGFR was 82 (IQR 63.4-91) ml/min, with 3 patients (7.9%) developing new onset stage 3a chronic kidney disease.

Conclusions :

Large renal masses should not be considered imperative indications to radical nephrectomy. RPN proved to be a feasible and safe surgical option. The functional benefits of conservative treatment must be taken into account due to the expected long term survival of these patients.
