“…Both routes, either transperitoneal (TP) or retroperitoneal (RP), can be equally advocated (1,7,(11)(12)(13)(14)(15). A benefit of retroperitoneal LPN (LRPN) is the direct, rapid access to the posterior hilar structures and to posterior RMs allowing for less kidney' s mobilization and rotation (1,7,(12)(13)(14)(15)(16)(17)(18). LRPN avoids bowel mobilization, need for lysis of adhesions in patients with prior abdominal surgery and peritoneal cavity irritation through contamination of blood and urine (1,3,7,11,14,15).…”
