Nephrectomy: A comparative study between the transperitoneal and retroperitoneal laparoscopic versus the open...

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Laparoscopic nephrectomy techniques, including transperitoneal and retroperitoneal routes, are increasingly utilized.
• Limited comparative data exists for these laparoscopic methods versus traditional open nephrectomy regarding outcomes and complications.

Purpose of the Study:

• To compare the clinical outcomes and morbidity of transperitoneal laparoscopic nephrectomy (TLN), retroperitoneal laparoscopic nephrectomy (RLN), and open nephrectomy (Nx).
• To evaluate operative time, analgesic requirements, hospital stay, and convalescence periods for each surgical approach.

Main Methods:

• A comparative study involving 18 TLN, 17 RLN, and 19 Nx for benign renal disease.
• Analysis of key clinical data including operative duration, patient morbidity, analgesic use, and postoperative hospital stay.

Main Results:

• Open nephrectomy had a significantly shorter operative time (117 min) compared to TLN (206.5 min) and RLN (211.2 min).
• Laparoscopic approaches required less analgesia (1-2 days) and shorter hospital stays (6-7 days) than open surgery (4 days, 10 days).
• Convalescence was substantially faster after RLN (21 days) and TLN (24 days) compared to open nephrectomy (40 days).

Conclusions:

• Laparoscopic nephrectomy demonstrates a clear advantage over open surgery for benign renal disease.
• The retroperitoneal approach offers distinct benefits, particularly in terms of patient recovery and reduced postoperative morbidity.
