Abstrakt:	Objectives: Mesorenal tumors (those located in the renal middle line or between both poles) are complex cases for partial nephrectomy (PN). Our objective is to evaluate oncological and perioperative results of PN in these patients with mesorenal tumors greater than 4 cm, mesophytic or endophytic. Methods: A review of the medical records of patients with tumors with these characteristics operated between January 2016 and June 2016 was performed. Results: 36 cases were included. The mean age was 54.2 years (24-79) with 12 cases of male gender. Mean surgical time: 139 minutes (120-280); 30 cases with complete clamping with mean ischemia of 19 minutes (10-90) and 6 compression of the parenchyma. Mean estimated bleeding: 280 ml (100-900). Mean tumor diameter: 4.3 cm (4.0 to 7.6). Preoperative and postoperative mean glomerular filtration rate 89 ml/min and 76 ml/min (p=0.32) respectively. Median length of stay: 3.8 days (2-21). There were 2 (6.5%) complications (II and IIIb). One case (3.3%) presented positive margin. One patient died due to progression at 14 months. With a median follow-up of 52.1 months (10-168) no recurrences were observed. Conclusions: We consider that mesorenal tumors, with significant penetration within the renal parenchyma and greater than 4 cm, PN presents both oncological and satisfactory results.
