Comparison of right and left laparoscopic live donor nephrectomy

Area of Science:

• Urology
• Transplant Surgery
• Surgical Anatomy

Background:

• Laparoscopic live donor nephrectomy (LDN) is a common procedure for kidney transplantation.
• Understanding anatomical and functional differences between right and left kidneys is crucial for optimizing donor nephrectomy outcomes.

Purpose of the Study:

• To compare the anatomical characteristics and functional outcomes of right versus left kidneys obtained through laparoscopic live donor nephrectomy.

Main Methods:

• Retrospective analysis of 84 transperitoneal laparoscopic live donor nephrectomies (66 left, 18 right).
• Comparison of renal vein and artery lengths, operative times, and need for back-table reconstruction.
• Evaluation of graft function using serum creatinine levels at 3 months post-transplant.

Main Results:

• Left kidneys exhibited significantly longer renal veins (38 vs 27 mm) compared to right kidneys.
• No significant difference was observed in renal artery length between right and left kidneys.
• Right-sided LDNs were associated with shorter operative durations (132 vs 182 min) but required more frequent back-table renal vein lengthening (3/18 vs 0/66).

Conclusions:

• Despite technical advantages in operative time, right-sided LDN necessitates greater attention to renal vein length and potential reconstruction.
• The functional outcomes, as assessed by serum creatinine at 3 months, are equivalent for both right and left kidneys following LDN.
• These findings support the feasibility of right-sided LDN while emphasizing the need for careful pre-operative assessment and surgical planning regarding venous anatomy.
