Urography and Isotope Renography Following Renal Transplantation

Abstract

The clinical yield from routine urography following renal transplantation was compared with that from isotope renography. In 50 recipients of renal transplants, 59 urograms and 55 renograms were studied. The most common pathologic finding at urography was renal papillary necrosis (in 6 patients). This condition had no obvious correlation with the further fate of the transplant. There were no other significant pathologic changes. It is concluded that isotope renography can be regarded as sufficient for routine follow-up. One baseline urogram is usesul, but additional urographies should be carried out only when clinically indicated.
