Renal artery atherosclerosis is an important triggering factor for thrombosis followed by impairment of renal function and viability. The acute occlusion of the renal artery by a thrombus or an embolus is an unusual and potentially reversible cause of renal failure. However, the duration and degree of arterial occlusion compatible with the viability of the renal parenchyma have not been well established, hence the importance of early diagnosis and intervention. The purpose of this study is to describe a case of renal artery thrombosis of a functionally single kidney, with late and spontaneous thrombolysis followed by unexpected functional recovery.
