Bilateral ectopic ureteroceles complicated by a large calculus within the left ureterocele in a dog

Abstract

A 4‐year‐old, entire female Siberian husky was presented with a history of urinary incontinence since she was a puppy and intermittent haematuria. A diagnosis of bilateral ectopic ureteroceles, calculus in the left ureterocele and bilateral pyelectasia was made by ultrasonography and CT excretory urography. The ureters were visualized communicating with opacified oblong structures, both located in the bladder neck, and the left one extended into the urethra. Resection of ureteroceles, neoureterostomy and calculus removal was performed. The dog made an uneventful recovery and was discharged from the hospital after 36 hours. A 2‐week course of antibiotic treatment was followed (marbofloxacin). Chemical analysis of the calculus revealed that it was composed of struvite. Treatment is mandatory at the time of diagnosis to prevent chronic kidney injury and urolithiasis secondary to obstructive uropathy. To the best of our knowledge, this is the first description of bilateral ectopic ureteroceles associated with calculus in a dog.
