Dysuria due to urachal abscessation in calves diagnosed by contrast urography.

Two heifer calves with dysuria were presented to the Large Animal Clinic of the Western College of Veterinary Medicine. Although no external indications of omphalitis were present, urachal abscessation, resulting in impeded urinations, was highly suspect due to the age of the animals. Intravenous contrast urography showed abnormal bladder position in both cases and consequently afforded a presurgical diagnosis. The cases and the diagnostic techniques employed are discussed.
