TRANSPERITONEAL VERSUS RETROPERITONEAL LAPAROSCOPIC PARTIAL NEPHRECTOMY: PATIENT SELECTION AND PERIOPERATIVE OUTCOMES

We perform TLPN for all anterior or lateral tumors as well as for large or deeply infiltrating posterior tumors that require substantive resection (heminephrectomy). The limited retroperitoneal space makes RLPN technically more challenging but provides superior access to posterior and particularly posteromedial lesions. When feasible, we prefer to perform laparoscopic partial nephrectomy by the transperitoneal approach because of its larger working area and superior instrument angles for intracorporeal renal reconstruction.
