Abstract
In 15 patients with extravasation of urine computed tomography (CT) findings immediately after urography were studied. In 11 patients leakage of urine was a postoperative complication. The extent of urine collections was better demonstrated by CT than urography in seven cases. Two patients had recurrent or residual tumor that was shown only by CT. One patient had an unsuspected second site of extravasation localized by CT. Diagnostic information obtained from the CT scan may be useful in planning appropriate treatment.
