Computed tomography, ultrasonography and gamma camera scintigraphy after renal transplantation

In routine postoperative observations on 31 transplanted kidneys, computed tomography (CT), ultrasonography (US) and gamma scintigraphy (GS) were compared with respect to diagnosis of abscess or lymphocele in the vicinity of the transplant, rejection and outflow obstruction. The results showed that US was the most reliable procedure for detecting fluid-filled cavities. In cases of graft rejection, GS was of most value. In demonstrating outflow obstruction, there was no definite difference between the three methods.
