title: Computed tomographic excretory urography features of intramural ectopic ureters in 10 dogs.
abstract: OBJECTIVE
  To describe the morphologic and morphometric computed tomographic excretory urography features of intramural ectopic ureters in dogs.
  
  
  METHODS
  Retrospective evaluation of computed tomographic excretory urography studies in 10 dogs with surgical and/or cystoscopically confirmed intramural ectopic ureters. All studies were assessed for ureteral ectopia, dilatation, tortuosity, ureterovesicular junction morphology and ureteral orifice location.
  
  
  RESULTS
  A total of 14 intramural ectopic ureters were confirmed at surgery/cystoscopy with reviewers correctly identifying 100% (14/14). Abnormalities on computed tomographic excretory urography included ureteral dilatation (7), ureteral tortuosity (3), lack of a normal ureterovesicular junction (14), urethral ureteral orifice location (14) and lack of ureteral divergence (14).
  
  
  CONCLUSIONS
  Lack of a normal ureterovesicular junction, a urethral-ureteral orifice location and lack of ureteral divergence are common computed tomographic excretory urography findings in dogs with intramural ectopic ureters. This technique requires further investigation to determine whether it might allow differentiation of intramural and extramural ectopic ureters.
