case_images: Differential cortical tracer uptake of the left kidney and the right kidney was 51.45% and 48.55%, respectively (Figure 3).
case_images: Pre-operative MAG-3 renogram. Left kidney (dotted blue line) illustrating an obstructive pattern of drainage with improvement in excretion with a diuretic (solid blue line), in comparison to the right kidney (solid pink line). MAG-3: Technetium-99m mercaptoacetyltriglycine

case_images: The dynamic images reflected dilatation of the left pelvi-calyceal system and the entire length of the left ureter, which persisted 70 minutes post micturition (Figure 4).

case_images: As shown in Figure 7, the previously observed left ureterohydronephrosis markedly improved.

case_images: In comparison to the preoperative MAG-3 renogram in which the left kidney failed to drain until diuretic administration, the postoperative MAG-3 renogram revealed slow but immediate excretion followed by an exceptional response to a diuretic (Figure 8).
