In order to analyze the number and length of the renal arteries and to evaluate abnormalities of the renal parenchyme and vessel digital subtraction angiogram images of 105 potential renal donors(45 men and 60 women aged 17-66 years) were studied retrospectively. For the entire series 31 donors had multiple renal arteries on one side (15 on the left 11 on the right) and 5 donors on the both sides. 89 donors were family related either paents or siblings of recipients. The estimation of the length of the renal artery was based on the mean height of the second lumbar vertebral body(L2) the right renal artery is significantly loner than on the left and measured more than the height of L2 vertebral body in 84 cases on the right and 60 cases on the left. twenty two dnors underwent right nephrectomy dut to presence of multiple renal arteries on the left (N=14) proximal bifurcation of left main renal artery (N=3) and young females in reproductime age(N=5) Unexpected abnormalities found with angiogram were seen in 7 cases and they include renal artery stenosis (N=2) renal cysts (N=4) and focal were seen in 7 cases and they include renal artery stenosis (N=2) renal cysts (N=4) and focal infarction (N=1) In cases of the renal cysts and focal infarcation. there were no serious complications related to the abnomalities. It is concluded that intra-arterial digital subtraction angiography is safe and efficient method to image renal anatomy of the potential renal donors.
