Abstract


Introduction

Partial nephrectomy is considered the gold standard procedure in managing small renal masses less than 4cm. Minimal invasive surgery is a alternative option in those cases. Laparoscopic partial nephrectomy has equivalent oncological results with open partial, offering in the same time all the advantages of minimal invasive surgery. The purpose of our study is to present our initial experience in laparoscopic partial nephrectomy.

 

Material and Methods

Between October 2012 and March 2014 , 9 selected patients with enhancing renal masses observed by CT scan, were submitted to laparoscopic partial nephrectomy . Patient demographics, preoperative tumor characteristics and detailed operative , postoperative and pathologic data were collected.

 

Results 

6 patients had a right partial nephrectomy and 3 a left one, with no intraoperative complications. In one patient a laparoscopic radical nephrectomy was done because of bleeding. The  operation time ranged from 120 to 225 min, estimated blood loss (EBL) ranged from 30 to 300 ml and warm ischemia time (WIT) ranged from 15 to 42 min. One patient didn't require any hilar clamping. Overall, no transfusions were necessary and there were no intraoperative or   major  postoperative adverse events. One patient occurred with a small subcutaneous haematoma in a port side and another one with a slight transient haematuria which was resolved spontaneously. There was one patient with a microscopic positive surgical margin and all patients are disease free at the 6 month follow up 

 

Conclusion 

Laparoscopic partial nephrectomy is a safe and feasible approach in small renal masses, offering all the advantages of minimal invasive surgery
