Strategies to Lessen Calciuria in Dogs and Cats with Recurrent Calcium Oxalate Urolithiasis

摘要

Calcium oxalate urolithiasis is one of the most common calculi found in dogs and cats.1 Middle-aged (8 to 12-year-old) castrated male dogs have increased risk for formation of calcium oxalate (CaOx) urolithiasis.2 Urolith formation is also associatedwith increased age. Certain breeds like Miniature and Standard Schnauzer, Lhasa Apso, Yorkshire Terrier, Bichon Frise, Shih Tzu, and Miniature and Toy Poodle, have increased risk for developing CaOx uroliths.2 Overweight dogs also have increased risk.2 Recurrent calcium oxalate urolithiasis (CaOx) is common in dogs and cats. The recurrence rate increases over time and it is estimated at 3% after 3 months, 9% after 6 months, 36% after 1 year, 42% after 2 years, 48% after 3 years, and 52% after 6 years in dogs.3 Given the high recurrence rate and inability to dissolve CaOx calculi, the treatment focus should be on prevention of recurrence after initial removal.
