title: Post re-anastomosis demonstration of regain in function in non-visualized upper half of kidney in a dual arterial allogenic renal graft on renal scintigraphy.
abstract: A young male patient with end stage renal disease underwent renal allograft having dual arterial supply. Immediate post-operative urine output dropped, an urgent Technetium-99m-mercaptoacetyltriglycine ((99m)Tc-MAG3) renogram revealed non-visualized upper-half and the preserved perfusion and parenchymal function of the small transplant kidney. Patient was re-explored and re-anastomosis was performed. A renogram at 24h post re-anastomosis revealed increase in the size of renal allograft, with preserved perfusion to the upper-half of transplant. Transplant kidney biopsy of the Upper-half showed acute tubular necrosis. 99mTc-MAG3renogram at 10 days post re-vascularization remains unchanged with persistent improvement at 2 months follow-up. We conclude that early recognition of renal functional loss allows early management and the high probability of salvaging the renal function.
