Identifying and localizing the site of post-renal transplantation urine leaks is important for patient management and treatment planning. Renal scintigraphy is a proven modality for confirming urine leaks after complicated post-renal transplantation. Routinely, renogram studies are performed with a clamped extraperitoneal drain. This results in the spread of radioactivity in the abdominal region, which makes localization of the leak site difficult in the planar images. Here we are trying to give an insight into minimalizing the accumulated urine volume by an unclamped extraperitoneal drain in order to precisely localize the site of the leak.
