Objective: To assess the outcome and safety of surgically placed artificial urethral sphincters in male dogs with urethral sphincter mechanism incompetence. Materials and Methods: We included dogs with urethral sphincter mechanism incompetence treated by placing an artificial urethral sphincter from January 1, 2010 to December 31, 2017. The continence score (scale 1 to 5, with 5 indicating complete continence) was evaluated before and after implantation. Follow‐up information was obtained from the institution's medical records (short‐term up to 12 months) and questionnaires were completed by telephone (long‐term ≥12 months) for evaluation. Results: Medical therapy was unsuccessful in 18 dogs and unknown in one dog before the artificial urethral sphincter placement. Short‐term continence improved in 16 of the 19 (84%) dogs. Four patients were lost to follow‐up. Nine of 15 (60%) dogs showed long‐term continence improvement, eight of 15 (53%) remained completely continent. The median follow‐up was 1785 (range 2 to 3234) days. The complication rate was 56% (9/16). Minor complications, including haematoma, stranguria/temporary dyssynergia and mild inflammation at the port, were reported in four of 16 (25%) dogs. Five of 16 (31%) experienced major complications, including stranguria/mechanical urethral obstruction, persistent dyssynergia, fistula at the port and port rotation. Clinical Significance: Artificial urethral sphincter placement is a valid option for treating incontinent male dogs that show an insufficient response or become refractory to medical or other prior surgical management. A high‐complication rate is associated with this procedure. [ABSTRACT FROM AUTHOR] |
