'''This is a one-year-old, female Terriermix breed presented for intermittent dribbling since its acquisition at three months
of age. This dog periodically voids the bladder normally.'''

|q1=What diagnosis is suggested by the contrast study?
|a1=
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.
The condition occurs most frequently in Siberian Huskies, Newfoundlands, Terriers, Golden and Labrador Retrievers and Toy Poodles; the mode of inheritance is unknown.
|l1=
|q2=What are five morphologic variations of this anatomic anomaly?
|a2=
The five morphologic variations of this anatomic anomaly are:
*Intramural ureter with the opening distal to the bladder sphincter. This is the most common type of ectopic ureter.
*Intramural ureter with no distal opening.
*Intramural ureter with two distal openings – one above and one below the bladder sphincter.
*Intramural ureter with a normal opening and a ureteral trough continuing distal to the sphincter.
*Extramural ureter that enters directly into the vagina or urethra without penetrating the bladder wall.
|l2=
|q3=What are the methods of choice for assessing the ureteral pathway and its termination?
|a3=
An excretory urogram in conjunction with pneumocystogram is useful to assess the presence or absence of an ectopic ureter.
Vagino-urethrography is also useful for evaluating the termination of the ureter.
Radiography cannot be used to identify the morphologic type of ectopic ureter.
