Laparoscopic living donor nephrectomy and multiple renal arteries

Area of Science:

• Nephrology
• Transplant Surgery
• Minimally Invasive Surgery

Background:

• Laparoscopic donor nephrectomy (LDN) is an emerging surgical technique for kidney donation.
• Short-term recipient renal function after LDN is comparable to traditional open donor nephrectomy (ODN).
• Long-term outcomes and suitability for donors with multiple renal arteries remain under investigation.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of Laparoscopic Donor Nephrectomy (LDN).
• To compare graft and patient survival rates between LDN and Open Donor Nephrectomy (ODN).
• To assess the impact of multiple renal arteries on LDN outcomes.

Main Methods:

• Retrospective review of 124 consecutive LDN procedures.
• Comparison with 117 historical Open Donor Nephrectomy (ODN) controls.
• Analysis of graft survival, patient survival, immunologic events, and ureteral complications.

Main Results:

• One-year actuarial graft and patient survival rates for LDN were 94% and 95%, respectively, not statistically different from ODN.
• The presence of multiple renal arteries did not negatively impact survival or immunologic outcomes.
• Initial recipient ureteral complication rates in LDN (11.2%) were higher than ODN (3.4%), but decreased to 7% after technical modifications, becoming non-significant.

Conclusions:

• Laparoscopic donor nephrectomy (LDN) is a safe and effective alternative to open donor nephrectomy (ODN) for living renal transplantation.
• Donor advantages of LDN are accompanied by equivalent recipient functional results.
• Technical refinements have addressed initial concerns regarding ureteral complications in LDN.
