| Abstract: | Tc-99m DTPA scintigraphic findings in patients with postoperative complications of renal transplantation were presented. In acute tubular necrosis, excretion of the tracer was not observed though its perfusion was preserved. In acute rejection, perfusion was reversibly disturbed. In chronic rejection, perfusion was irreversibly disturbed. In renal infarction, multiple defects were observed. In renal vein thrombosis, similar pattern to acute tubular necrosis was found but RI venography was helpful. In lymphocele, perirenal photon deficiency was observed. In renal artery thrombosis, absence of the perfusion and total photon deficient were noted. Tc-99m DTPA renal scintigraphy is useful for diagnosis and follow up of the complications of transplanted kidneys. |
