Plain-English summary
A 7-year-old Swedish Warmblood mare was experiencing urinary incontinence, which means she was unable to control her urination. This problem happened after a surgical procedure to remove a bladder stone, which damaged her urethral sphincter, the muscle that helps keep urine in the bladder. The veterinarian successfully repaired the damaged muscle by stitching the ends back together. After the surgery, the mare was able to control her urination again, showing that the treatment worked well.
Abstract
OBJECTIVE: To describe successful surgical treatment of urinary incontinence caused by a ruptured and/or transected urethral sphincter in a mare. STUDY DESIGN: Clinical report. ANIMAL: A 7-year-old, Swedish Warmblood mare with urinary incontinence. METHODS: The urethral sphincter, which had been damaged during removal of a cystic urolith, was repaired by apposing the ends of the disrupted urethralis muscle and tunica muscularis. RESULTS: The mare was no longer incontinent after repair of the defect by apposition of the ends of the urethralis muscle and tunica muscularis. CONCLUSIONS: Transection and/or rupture of the urethral sphincter of a mare may result in urinary incontinence. CLINICAL RELEVANCE: Apposition of the ends of the ruptured or transected urethralis muscle and tunica muscularis can correct urinary incontinence caused by this defect.
