A 10-month-old, unilateral cryptorchid, male English bulldog underwent urethropexy for the treatment of urethral prolapse. Six hours after surgery the dog developed dysuria, haematuria, discomfort, severe penile oedema, inflammation, and inability to extrude the penis from the prepuce. Urethral patency was restored by placing an indwelling catheter into the urethral lumen. Penile swelling was managed with cold and warm compresses for 2 days, and antibiotics, nonsteroidal anti-inflammatory drugs, and opioids for 4 days. Complete resolution of the swelling was evident by 3 days after surgery. One year after surgery the dog was reported to be in good health.
