Unraveling the Cause of Anuria Post Kidney Transplantation by Renal Scintigraphy.

A dynamic renal scintigraphy is widely used after renal transplantation to evaluate transplant function and possible complications. We report the case of a 27-year-old man with persisting anuria after kidney transplantation. A renal scintigraphy using Tc-ethylenedicysteine followed by SPECT/CT of the abdomen was performed showing tracer accumulation in the colon without any activity in the bladder, as a result of ureter reimplantation onto the sigmoid instead of onto the previously reconstructed bladder. Renal scintigraphy identified the cause and localization of the urinary leak, which led to immediate surgical reimplantation of the ureter onto the augmented bladder with onset of diuresis.
