Contribution of SPECT/CT to Evaluate Urinary Leakage Suspicion in Renal Transplant Patients.

It is known that renal scintigraphy is the best imaging modality in the diagnosis of urinary leakage. Usually, only planar images are diagnostic but sometimes they are unclear when urinoma is small and adjacent to kidney or bladder. In other respects, planar images can be false-positive in the case of increased blood flow of abdominal wall. We suggested using SPECT/CT in differential diagnosis. An atlas of SPECT/CT is presented, which includes 3 cases that urinoma was diagnosed by SPECT/CT, which were unclear on planar images, and one case that urinary leakage suspicion on planar image was ruled out by SPECT/CT.
