The retroperitoneal laparoscopic approach is displacing open surgery and transperitoneal approach for several benign renal conditions. In the past 6 years we have performed 20 procedures, 10 with lateral position and 10 with posterior prone one: 13 total nephrectomies and 7 heminephrectomies in children aged 4,1 years on average. Mean operative time was 200 minutes in partial procedures and 278 in the total ones. Oral feeding was restored to 11,4 hours and average hospital postoperative stay was 1,58 days in total nephrectomies and 2,18 in heminephrectomies. There was no intraoperative bleeding. Complications were two urine leaks, two infections due to residual ureteral stumps and a case of transient hematuria. There were no significant differences between posterior and lateral approaches as to hospital stay, time of onset of oral feeding or complications, although the average operative time was shorter in the posterior approach (mean 170 min, SD 17,3) than in the lateral one (mean 216 min, SD 41) (P=0,024) in total nephrectomies. Retroperitoneoscopy allows a safe access to the kidney and avoids morbidity associated with the transperitoneal access. The posterior approach provides better vascular control, maintains the peritoneum far and allows the procedure with fewer ports, maximizing work space. |
