Plain-English summary
A 2.5-year-old female neutered Maine Coon cat was brought in for urinary incontinence, which means she was unable to control her urination. An ultrasound revealed a problem with her right kidney and ureter, showing that she had a duplicated kidney and an ectopic ureter (a ureter that connects to the urethra instead of the bladder). The vet performed surgery to correct this by ligating the ectopic ureter and creating a new connection to the bladder. After the surgery, the cat's incontinence was resolved, and she had no complications five months later.

Abstract
A two-and-a-half-year-old female neutered Maine Coon cat was presented for investigation of urinary incontinence to an academic referral hospital. An ultrasound of the abdomen performed at the referring veterinarian showed a distended ureter with no clear ureterovesical junction visible. The cat was referred for further investigations and treatment. Ultrasound, cystoscopy and computed tomography urography were performed. A duplication of the right kidney with a separate and ectopic duplicated ureter, joining the right dorsolateral aspect of the urethra, was diagnosed. A normal ureter was closely associated with the ectopic ureter and entered the bladder at the level of the trigone. The left kidney and ureter were normal in appearance. The ectopic ureter was ligated before entering the urethra and neoureterocystostomy of the dilated ectopic ureter was performed without complications. Incontinence resolved following surgery, and the patient showed no clinically apparent complications 5 months post-surgery.
