Plain-English summary
An 8-month-old male English Bulldog was brought in after a surgery to remove an undescended testicle caused an accidental cut in his urethra. After the surgery, he developed kidney problems due to a blockage in his ureters, which carry urine from the kidneys to the bladder. The vet suspected this was caused by severe inflammation from the initial injury. To fix the blockage, the vet placed stents in both ureters, which helped resolve the kidney issues. The dog was also treated for urinary infections and incontinence, but after 46 months, he showed no ongoing urinary problems.

Abstract
An 8-month-old male English Bulldog was presented to an academic referral center following iatrogenic urethral transection during an elective unilateral cryptorchidectomy. A contrast cystourethrogram demonstrated contrast leakage from the pre-prostatic urethra. An exploratory laparotomy confirmed ligation and transection of the pre-prostatic urethra, and a urethral anastomosis was performed. Postoperatively, the patient developed progressive azotemia, and abdominal imaging revealed bilateral hydroureter and hydronephrosis consistent with bilateral ureteral obstruction. No apparent cause of mechanical obstruction was identified during the subsequent ultrasound, cystoscopy, or laparotomy. A functional ureteral obstruction was suspected to be caused by acute, severe inflammation of the urinary bladder following the initial urethral trauma and subsequent ischemic injury, resulting in the occlusion of the ureteral papillae. Bilateral ureteral stents were surgically placed, and the azotemia resolved. Following stent placement, the dog was treated for recurrent multidrug-resistant urinary infections and urinary incontinence. The owner reported no persistent lower urinary signs during a follow-up call 46 months following the cryptorchidectomy.
