Bladder Stones

Abnormal concretion of mineral salts that form in the bladder under certain conditions and can lead to obstruction of the urethra. Typically crystals will be noted in the urine prior to the formation of the stones. The two most common types of bladder stones are Calcium Oxalate (CaOx) and Struvite, though others can also be found. Stones can be found when the urine has a very high or very low pH, is highly concentrated, has inflammation or infection present, or has high levels of certain substances due to the pet’s diet. Some bladder stones can be dissolved, other times surgical removal is the treatment of choice. Due to the effect that diet has on the urine, a prescription diet is often recommended to prevent crystals and stones from forming in pets that are at risk.
