Post-transplant Renal Artery Stenosis: A Cause of Anuria. Report of 2 Cases Corrected by Revascularization

Abstract

We report 2 cases of severe hypertension and acute onset of anuria after renal transplantation in which angiography revealed renal artery stenosis. After renal artery reconstructive surgery renal function returned to normal and the hypertension improved, A high index of suspicion is needed to make the diagnosis. Only by heightened awareness of this important entity will patients with posttransplantation anuria secondary to renal artery stenosis be identified. Such patients may benefit from renal artery revascularization to reverse this type of renal failure.
