Nephroureterectomy and Ureteroneocystostomy in an Alpaca With Bilateral Ectopic Ureters Diagnosed by Computed Tomographic Excretory Urography

A 5-month-old domestic shorthair cat was presented for evaluation of urinary incontinence since birth. Excretory urography revealed dilated double ectopic ureters draining a hydronephrotic right kidney. Urine culture yielded a pure culture of Klebsiella pneumoniae. The cat was treated initially with bactericidal antibiotics, followed by right-sided nephroureterectomy. The surgery and antibiotic therapy led to complete resolution of urinary incontinence and urinary tract infection. Ureteral duplication is an unusual congenital anomaly that has not been previously reported in the cat.

Ureteral pseudodiverticulosis is rarely reported in veterinary medicine. This case study aimed to describe the radiographic, ultrasonographic and computed tomographic findings for dogs with radiologically confirmed ureteral pseudodiverticulosis. Three dogs met the inclusion criteria. Radiographic findings included multiple small, round-shaped mineral opacities located around the periphery of the ureters (3/3), and multiple contrast medium-filled outpouchings that appeared and disappeared when the contrast medium washed in and out on intravenous excretory urography (2/3). The outpouchings were approximately 1 mm in diameter. In the ultrasonographic images, the mineral foci were located adjacent to the ureter, but not within the ureteral lumen (1/3). Contrast-enhanced CT findings were similar to those of excretory urography (2/3). Ureteral pseudodiverticulosis should be considered in the differential diagnosis for old-aged and small-breed dogs with radiopaque materials along the ureteral pathways; excretory urography or contrast-enhanced CT are recommended for a more definitive imaging diagnosis.

Ureteral ectopia is a well-described cause of urinary incontinence in female dogs, but this condition has not been completely characterized in male dogs. Sixteen male dogs with ectopic ureters were evaluated between Jan 1999 and Mar 2007. Male dogs were similar to female dogs with ectopic ureters in terms of breed, presenting complaint, age of onset, and bilateral nature of the ectopia. Diagnosis was made by expert interpretation of imaging techniques such as excretory urography and contrast-enhanced computed tomography (CT). Overall, 11 of 13 dogs that had surgical correction of ectopic ureters were incontinent preoperatively. Urinary continence was restored in 82% of those dogs.
