Urograms were performed on 16 adult koalas to evaluate this procedure for use in the koala. Because there is only a small amount of intraabdominal fat, radiographs of the abdomen of koalas lack detail. Contrast medium was excreted more slowly in the koala than in the dog and there was considerable variation in the rate of excretion between koalas. The results of this study indicated that urography was a valuable technique for assessing renal anatomy, but there was considerable variation in the time for excretion of the contrast medium.
