Bilateral ectopic ureters in a Labrador Retriever puppy
Silver, Ebony N.
Ectopic ureters are a rare malformation of the urogenital system whereby the ureter abnormally inserts at a site distal to the trigone of the bladder. Commonly seen in young female dogs with urinary incontinence, the disorder is most often diagnosed with the use of various imaging modalities such as ultrasound, excretory urography and retrograde positive contrast vaginourethrography. These imaging modalities allow for visualization of the basic size, shape and location of the kidneys, ureters and bladder. There are several types of ectopic ureters including intraluminal, extraluminal, ureteral troughs and double ureteral openings. The type of ectopic ureter and the extent of concurrent renal dysfunction ultimately dictate the type of surgical technique necessary to correct the malformation. Typically, an intraluminal ureter is corrected via a neoureterostomy and extraluminal ureters are corrected via a ureteroneocystostomy. The prognosis for post surgical resolution of urinary incontinence [is] fair and is highly dependent on post-surgical complications and the presence of concurrent urogenital abnormalities. A case of bilateral ectopic ureters in a young Labrador Retriever including case history, diagnosis, surgical technique and outcome are discussed in detail.
