If I understand the : Question correctly, the left kidney renogram shows decreased uptake of tracer, which means decreased kidney function. The negligible wash out means little urine production, or possibly a blockage of the upper ureter. Please discuss with your doctor, as this appearance needs to be correlated with your medical condition and the reason your doctor ordered the test.
