Right Versus Left Laparoscopic Living-Donor Nephrectomy: A Meta-Analysis

Area of Science:

• Nephrology and Transplant Surgery
• Minimally Invasive Surgical Techniques

Background:

• Laparoscopic living-donor nephrectomy is a common procedure for kidney transplantation.
• Limited comparative studies exist on the safety and efficacy of right versus left laparoscopic living-donor nephrectomy.

Purpose of the Study:

• To compare the outcomes of right versus left laparoscopic living-donor nephrectomy through a meta-analysis.
• To evaluate operative parameters, complications, and graft function between the two approaches.

Main Methods:

• A meta-analysis of published studies comparing right and left laparoscopic living-donor nephrectomy was conducted.
• Databases searched included Medline (PubMed), Embase, Ovid, and Cochrane from January 2000 to January 2014.
• Key outcomes assessed were operative time, blood loss, complications, graft function, and hospital stay.

Main Results:

• The right kidney group demonstrated shorter operative times and lower operative blood loss compared to the left kidney group.
• A higher rate of donor intraoperative complications was observed in the left kidney group.
• No significant differences were found in graft loss, delayed graft function, or postoperative complications between the right and left groups.

Conclusions:

• Right and left laparoscopic living-donor nephrectomy exhibit comparable surgical and postoperative graft function outcomes.
• Surgeons may consider either kidney for transplantation if bilateral renal function is similar.
• The longer renal vein of the left kidney may simplify the procedure, suggesting a potential preference for left-sided donation in practice.
