Laparoscopic living donor nephrectomy and multiple renal arteries.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) is a new technique. While the short-term recipient renal function is equivalent to that of the traditional open nephrectomy (ODN), long-term function and potential exclusion criteria, such as the presence of multiple renal arteries, are as yet unknown. METHODS: Retrospective review of 124 consecutive LDN performed from March 1996 to September 1997 with 117 ODN as historical controls. RESULTS: The 1-year actuarial graft and patient survival for LDN kidneys were 94% and 95%, respectively. These were not statistically different from that of the ODN controls. The presence of multiple renal arteries did not alter graft and patient survival or prevalence of immunologic events. The number of recipient ureteral complications in the LDN group was 11.2% compared with 3.4% in ODN (P < 0.01). Following correction for a learning curve with accompanying technical modifications, the prevalence of recipient ureteral complications has decreased to 7% in the last 94 patients (P = nonsignificant versus ODN). CONCLUSIONS: LDN represents a viable alternative to ODN for living renal transplants. Advantages for the donor are matched by equivalent functional results for the recipients.
