Abstract

An intact male, 3-month-old, Great Pyrenees mountain dog, weighing 7.3 kg with a history of severe hematuria during 2 months was referred. Hematology showed mild leukocytosis. There were no remarkable findings in abdominal radiographs due to ingesta and gas in the gastrointestinal tracts. Ultrasonographs showed bilateral hydronephrosis, bilateral dilated and tortuous ureters, and hyperechoic sludges in the urinary bladder (UB). And a dilated cavity was identified cranial to the UB. Excretory urography and cystography were performed to examine the cause of hydronephrosis and an abnormal cavity cranial to the UB. Bilateral ureters were tortuously dilated and opened into the craniodorsal part of the UB. An abnormal cavity was connected to the UB at the left cranioventral part of the UB. Therefore bilateral ectopic ureters and urachal remnant were diagnosed.
