*Ultrasound examination of the bladder after residual air and contrast has been removed and the bladder moderately filled with sterile saline. This allows identification of ureterovesical junctions and visualization of ureteral jets from ureters entering the trigone normally. Alternatively, direct visualization of ureteral emptying with fluoroscopy. | *Ultrasound examination of the bladder after residual air and contrast has been removed and the bladder moderately filled with sterile saline.

A two-year-old, neutered female Giant Schnauzer presented with urinary incontinence of several months’ duration. The dog leaked when recumbent and the severity of the incontinence varied. The dog was otherwise normal. She was spayed at 11 months old after her first season and was not incontinent as a puppy.

This radiograph was obtained. What is your main differential diagnosis? | In this case the history, lack of specific findings on clinical and radiographic examinations, and presence of an intrapelvic bladder neck on the radiograph were highly suggestive of urethral sphincter mechanism incompetence. The dog responded well to treatment with phenylpropanolamine and subsequent colposuspension. Other common causes of urinary incontinence were ruled out by the above investigation. |
