Fig1
Renal artery dopplers (Fig. 1) were performed which revealed greater than 60% stenosis of the proximal left renal artery and at least 60% stenosis of the distal right renal artery.
Computerized tomography of the right (a) and left (b) proximal renal arteries (arrows). Approximately 50% stenosis of the left renal artery is noted

Fig2
Computerized tomography angiography showed approximately 50% stenosis of the proximal left renal artery without stenosis of the right renal artery (Fig. 2).
