title: Intraureteral tumor demonstrated by computed tomography.
abstract: Two cases of papillary carcinoma of the bladder are presented in which the ureter could not be demonstrated by standard radiographic techniques. Computed tomography (CT) allowed identification of the tumor filled ureter. Intraureteral papillary tumor has a radiographic density (CT number) above that of water but less than that of the enveloping ureter.
