sodium-pertechnetate-tc-99m and Kidney-Tubular-Necrosis--Acute

A 35-yr-old patient developed severe acute tubular necrosis requiring hemodialysis. A [99mTc]dimercaptosuccinic acid scan of the kidneys showed no renal uptake at 4 or 24 hr, but the patient subsequently recovered normal renal function as judged by a normal serum creatinine. Based on this case report and a review of the literature, one cannot assume irreversible loss of function in patients with acute renal failure, based on the absence of radiopharmaceutical uptake by the kidneys.

131Iodine hippurate sequential scintigrams obtained after transplantation contain prognostic information about the long-term development of a graft. Results of 131 131iodine hippurate sequential scintigrams made within 48 hours after graft implantation were compared to the graft status 2 years after transplantation. Hippurate uptake and transport were rated on a 4-step scale. Disturbed hippurate uptake and abnormal tracer transit were associated with increased frequency of early graft destruction and with a high frequency of chronic rejection. The chi-square test demonstrated a significant relationship between results of the initial hippurate scintigrams and long-term graft development.
