Nuclear medicine - Tc-99m DMSA
left kidney is seen at its normal anatomical position and shows non-homogeneous distribution of the radiotracer. A cold area suggestive of scarring, is noted at its upper lateral pole
right kidney is visualised in the midline and slightly to the left of the lower abdomen. It is relatively small in size and shows reduced non-homogeneous radiotracer uptake. A cold area suggestive of cortical scarring, is seen at its upper pole. No fusion is seen between the kidneys
differential function: Left kidney contributes 75% while right kidney contributes 25% of total renal function
