Objective: To describe the successful management of pelvic urethral strictures in 3 young cats (1 after perineal urethrostomy, 1 after a third-time urethral obstruction, and 1 with prolonged lower urinary tract signs post-urethral obstruction) using balloon dilation and a short-term, indwelling urethral catheter.Case Summaries: A 9-month-old neutered male domestic longhair cat with a urethral obstruction and a suspected congenitally narrowed urethra was treated via perineal urethrostomy. The cat later developed acute kidney injury, multidrug-resistant urinary tract infections, and a pelvic urethral stricture. A second case, a 2.3-year-old neutered male domestic shorthair cat, developed a stricture of the pelvic urethra after multiple obstructions and catheterizations. A third case, a 1.2-year-old neutered male domestic shorthair cat, had persistent and prolonged lower urinary tract signs after treatment for a urinary obstruction. The cat also had an abnormally small urethral opening and was ultimately found to have a proximal urethral stricture. The strictures in all 3 cases were successfully treated with a combination of fluoroscopic-guided balloon dilation and short-term indwelling urethral catheterization while managing any present infection.
