Plain-English summary
A 12-year-old Thoroughbred stallion was having severe belly pain, which was found to be caused by a blockage in his urinary tract due to a stone and a possible rupture of his bladder. After treating the bladder issue and removing the stone, the stallion developed a narrowing in his urethra (the tube that carries urine out of the body). Initial treatments to fix the stricture, including a catheter and balloon dilation, did not work. Eventually, a special absorbable stent was placed in the urethra to help keep it open, and follow-up examinations showed that the stent was successfully absorbed by the body and the stallion was able to urinate normally. Overall, using the absorbable stent was an effective solution for this stallion's urethral stricture.
Abstract
OBJECTIVE: To describe the successful management of a urethral stricture with an absorbable stent in a stallion. STUDY DESIGN: Clinical report. ANIMALS: Stallion with a urethral stricture. RESULTS: A 12-year-old Thoroughbred breeding stallion was evaluated for acute onset of colic. Uroperitoneum because of presumptive urinary bladder rupture, with urethral obstruction by a urethrolith, was diagnosed. The uroperitoneum was treated conservatively. The urethrolith was removed through a perineal urethrotomy. Approximately 15 weeks after urethrolith removal, the stallion presented with a urethral stricture. The stricture was unsuccessfully treated with an indwelling urinary catheter and 4 attempts at balloon dilation. Eight weeks after diagnosis of stricture, an absorbable polydioxanone (20 mm × 80 mm) urethral stent was implanted under percutaneous, ultrasound guidance. Urethroscopy was performed at 70, 155, and 230 days after stent placement and the endoscope passed through the affected site without complication. Urethroscopy at 155 days showed the stent had been reabsorbed. Follow-up 20 months after stent placement reports the stallion was able to void a normal urine stream. CONCLUSIONS: Absorbable urethral stent placement was a feasible treatment for urethral stricture in this stallion.
