Canine Calcium Phosphate

These radiopaque stones are similar to calcium oxalate, but are more common in dogs with hypercalcemia.

Calcium phosphate uroliths (hydroxyapatite, brushite, whitlockite, and octacalcium phosphate) are uncommon in dogs. Common conditions associated with these minerals include hypercalcemia, hyperparathyroidism, hypervitaminosis D, and dystrophic and ectopic mineralization of vital tissues (blood clots, urothelium, etc.).

Calcium phosphate uroliths include apatite, brushite, and octacalcium phosphate. • Serum calcium. Investigate causes for hypercalcemia, when present.

• Correct hypercalcemia based on cause (e.g. parathyroidectomy for primary hyperparathyroidism). • Hydrochlorothiazide with highly recurrent stones (2mg/kg q12-24 hr).

• Lower sodium foods that do not overly acidify urine (e.g. c/d multicare, u/d, g/d, others). If needed, feed canned therapeutic foods or add water to achieve a urine specific gravity less than 1.020.

Urinalysis every 3 to 6 months to adjust pH to 6.5 to 7.5, and urine specific gravity to 1.020 or lower. Medical imaging every 6 to 12 months to detect recurrent stones when small to permit their easy removal without surgery.

Nous vous conseillons de consulter la documentation du fabricant concernant certains aliments thérapeutiques afin d'en déterminer les indications et les contre-indications. Pour les animaux présentant des problèmes de santé multiples, nous suggérons que le choix de l'aliment prenne en compte tous les besoins de l'animal en matière de santé.
