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.
