Rivera Gorrín – Renal artery stenosis of the kidney allograft is an infrequent finding, as is mechanical kinking of the artery. The right renal artery’s greater length in comparison to the vein, limited space within the iliac fossa, and post-operative shifting in graft components all increase the likelihood of kinking. Renal artery stenosis and kinking can either coexist or kinking can result in stenosis. Nevertheless, since both these abnormalities can be corrected with timely treatment, early diagnosis is crucial to prevent permanent to the renal allograft.
