Full history/Diagnosis is available below
Renal ultrasound performed the same day shows normal kidney morphology and normal gray scale appearance. No flow was detected within the renal artery.
Renal scintigraphy allows assessment of both perfusion and function in the transplanted kidney. Activity should be seen in the kidney 3-6 seconds after activity in the iliac artery. Peak activity in the graft should occur in less than 5 minutes, followed by prompt wash-out. In ATN, there is a slight reduction in perfusion, with significant parenchymal dysfunction. In rejection, there is decreased perfusion and relatively preserved function early, with reduction in both perfusion and function with more chronic rejection. In practice, it is usually not possible to definitively distinguish ATN from rejection based on the scintigraphic findings because there is considerable overlap of the findings for these two causes of renal dysfunction. In arterial thrombosis, there is severe or total reduction in perfusion and function.
