Original publication title: Endoscopic diagnosis of unilateral ectopic ureter in a yearling filly.
Plain-English summary
An 18-month-old female horse, known as a filly, was having a problem with chronic urine dribbling. To find out what was wrong, veterinarians used a special camera called an endoscope to look inside her body. They discovered that she had a condition called unilateral ectopic ureter, which means that one of her ureters (the tubes that carry urine from the kidneys to the bladder) was not in the right place. They used a medication that changed the color of her urine to help see the problem more clearly. The endoscopy showed that only one ureter was connected to her bladder and helped locate the misplaced ureter.
Abstract
Unilateral ectopic ureter was diagnosed by endoscopic examination in an 18-month-old filly examined because of chronic urine dribbling. Intramuscular administration of azosulfamide discolored the urine and enhanced visualization of the ectopic ureter. Endoscopy proved valuable in determining that only one ureter entered the urinary bladder and in locating the ectopic ureter in the ventral portion of the vagina.
