Bladder Stones in Pets
Bladder stones in pets, or uroliths, are commonly found in dogs and cats, and can cause urinary tract infection and blockage. The bladder stones found in pets are very similar to those found in humans. Most of these stones are composed of mineral salts from common elements, including phosphorus, calcium, magnesium, ammonia, and carbonates. Stones may form in the bladder, often in varying size and number. Types of bladder stones include struvite, calcium oxylate, urate, cystine, calcium phosphate, and silicate stones.
Bladder stones normally do not affect the rest of your pet's body unless the stones break off or lodge in the urethra, leading to potential urinary tract obstruction. This is especially a risk for male pets with a narrower urethra. In these emergency situations, your pet may often experience intense pain, vomiting, and severe blood electrolyte abnormalities such as a high blood potassium, acute kidney failure, bacterial infection, and death within a few days, if the obstruction is not relieved.
