Renal artery stenosis after renal transplantation

Renal artery stenosis occurred in eight of fifty patients who received a renal transplant during a three year period. The evaluation and management of these cases is summarized. Trauma associated with kidney procurement, preservation, or arterial anastomosis as well as the rejection process itself may contribute to the development of these lesions. Arteriography may be indicated at an earlier stage in patients who respond poorly to medical treatment of repeated episodes of "rejection."
