Laparoscopic living donor nephrectomy: is there a difference between using a left or a right kidney?

Area of Science:

• Nephrology
• Surgical Innovation
• Transplant Surgery

Background:

• Laparoscopic living donor nephrectomy (LLDN) is a common procedure for kidney donation.
• Comparison of outcomes between left and right kidney donation is crucial for donor safety and graft success.

Purpose of the Study:

• To compare intra- and postoperative outcomes of left versus right kidney laparoscopic living donor nephrectomy.
• To evaluate the safety and efficacy of using the right kidney for LLDN.

Main Methods:

• Retrospective review of 279 LLDN cases (260 left, 19 right) between 1998 and 2009.
• Comparison of pre- and postoperative renal function, surgical time, conversion rates, delayed graft function, and complications between left and right donor groups.

Main Results:

• No significant differences in preoperative renal function, surgical duration, postoperative donor creatinine, conversion to open surgery, or delayed graft function between left and right LLDN groups.
• Slightly higher intraoperative and major postoperative donor complications in the left kidney group, though not statistically significant.
• Reasons for right kidney selection included vascular variations, cysts, size, stones, and ureteral anatomy; the single right LLDN conversion occurred early in the learning curve.

Conclusions:

• Intra- and postoperative parameters are comparable between left and right LLDN.
• Right LLDN appears to be as safe and effective as left LLDN, despite a smaller sample size for right-sided procedures.
• Surgical experience and the learning curve significantly impact outcomes, as evidenced by the absence of conversions in recent years.
