Prospective randomized comparison of transperitoneal vs retroperitoneal laparoscopic simple nephrectomy

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Simple nephrectomy is performed for benign renal diseases.
• Laparoscopic techniques offer minimally invasive options for nephrectomy.

Purpose of the Study:

• To compare transperitoneal laparoscopic simple nephrectomy (TLN) versus retroperitoneoscopic simple nephrectomy (RSN) in a prospective randomized trial.
• To evaluate postoperative pain, analgesic requirements, and convalescence between TLN and RSN.

Main Methods:

• A prospective randomized study included 62 patients (31 TLN, 31 RSN) between January 2009 and August 2013.
• Primary endpoint was visual pain score; secondary endpoints included operative duration, complication rates (Clavien-Dindo), hospital stay, and time to normal activities.
• Statistical analysis used SPSS version 16.0 with significance set at P < .05.

Main Results:

• RSN demonstrated significantly lower visual pain scores (Day 1: 2.7 vs 4.9; Day 2: 1.1 vs 3.2) and reduced tramadol requirements (132.8 mg vs 167.3 mg) compared to TLN.
• RSN group experienced significantly shorter hospital stays and convalescence periods.
• Mean time to return to normal activities was significantly less for RSN (9.34 ± 4.9 days) versus TLN (16.7 ± 3.5 days).

Conclusions:

• Both TLN and RSN are feasible for benign renal diseases.
• RSN is associated with significantly less postoperative pain, reduced analgesic needs, shorter hospital stays, and faster recovery compared to TLN.
