[Outcomes of renal transplantation with donor kidneys with multiple arteries]

To compare the outcomes of renal transplantation with donor kidneys with multi-branched renal arteries.

The data about operation time, volume of intra-operational blood loss, postoperative complications, and post-operational renal function status of 251 recipients of donor kidneys with single-branched renal artery (Group A), 12 recipients of donor kidneys with double-branched renal arteries the diameter of one of which was < 2 mm or the estimated blood supply areas of one of which were < 10% (Group B), and 35 recipients of donor kidneys with renal arteries with 2 or more than 2 branches (Group C).

The operation time was (115 +/- 34) min in Group A and was (120 +/- 31) min in Group B, both shorter than that of Group C [(133 +/- 55) min], however, not significantly. There were not significant differences in the intra-operational volume of blood loss, 1-year survival rate of patient/transplanted kidney, and post-operational creatinine level among these three groups. The complication rate was 7.6% (19/251) in Group A, 16.7% (2/12) in Group B, and 11.4% in Group C (4/35).

There are not significant differences in the intra-operational status and post-operational outcomes among the operations of renal transplantation with donor kidneys with different amounts of renal arteries.
