title: Surgical treatment of a duplicated and ectopic ureter in a dog.
abstract: An eight-month old female bull mastiff was referred for evaluation of urinary incontinence. Contrast-enhanced computed tomography identified complete duplication of the left ureter with ectopic insertion of the duplicate ureter into the proximal urethra. Ureteroneocystostomy was performed, which improved but did not resolve urinary continence. To the authors' knowledge, this report details only the second reported case of duplicated ectopic ureter in the dog and the first documenting surgical reimplantation; thus, double-system ureteral ectopia should be considered as a possible differential diagnosis for urinary incontinence.
