“…The reported false-positive scintigraphic results can be explained by the use of radiotracer with hepatobiliary excretion, unusual anatomy of the collecting system, vesicoureteral refl ux, or the presence of the drainage bag within the fi eld of view during the scan [11,12]. These accumulations can be localized more accurately with the use of novel hybrid imaging systems such as singlephoton emission computed tomography/CT [13].…”

Simple provocative maneuvers in renal transplant scintigraphy for detecting urine leak

Urine leak in the early postoperative period following renal transplantation is a serious complication requiring early identification and aggressive intervention, which significantly reduces the morbidity and mortality. Renal transplant scintigraphy is a noninvasive method to evaluate the perfusion and function of a transplanted kidney and urinary drainage including urine leak. Here, we reported two cases in which the standard transplant renogram failed to demonstrate urine leak. The cases were referred for a diethylenetriaminepentaacetic acid renogram following the transplantation to evaluate the cause of symptoms or elevated serum creatinine level. In both the cases, urine leak was successfully detected following simple maneuvers such as diuretic administration or Foley catheter irrigation. Renal transplant scintigraphy is an effective and safe technique and the use of these simple maneuvers can enhance the diagnostic sensitivity of the transplant renogram in the detection of urine leak.
