Laparoscopic partial nephrectomy: Comparative study of the transperitoneal pathway and the retroperitoneal pathway

Transperitoneal and retroperitoneal approach in laparoscopic partial nephrectomy for posterior cT1 renal tumors: A retrospective, two-centers, comparative study

“…In our study, LRPN was associated with shorter OT. The difference in OT is probably due to the rapid access of LRPN to the tumor, avoiding bowel and extensive kidney mobilization, and due to the need for lysis of adhesions in the first cohort (1,3,7,(11)(12)(13)(14)(15)(16)(17)(18). It is worth-mentioning that we noticed intrabdominal adhesions in more patients of the group A than anticipated by the history of previous intraperitoneal operation and this might prolong OT.…”

“…A wide variety of endoscopic instruments and the steadily increasing laparoscopic experience rendered LPN a feasible treatment modality for cT1 RMs (1,7,(10)(11). 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).…”
