A 5-year-old neutered male Akita had a 5-month history of hematuria. Bilateral orthotopic ureteroceles were diagnosed using a combination of sonography, computed tomography (CT), and radiography. With CT excretory urography, the ureteroceles appeared as two intraluminal cystic structures in the vesicoureteral region of the urinary bladder, which directly communicated with dilated ureters. Unlike the other imaging modalities CT excretory urography provided a definitive diagnosis by confirming the communication between the hydroureters and the cystic dilations in the caudodorsal aspect of the urinary bladder.
