What diagnosis is suggested by the contrast study? | The excretory urogram shows ureteral ectopia; here the dilated left ureter drains into the urethra. It is a congenital disorder where one (70–80% of dogs) or both ureters (most cats) terminate and drain at a site other than the urinary bladder, most often in the urethra or vagina.

Vagino-urethrography is also useful for evaluating the termination of the ureter. Radiography cannot be used to identify the morphologic type of ectopic ureter. |
