This is an inherited metabolic disorder affecting the kidneys, where the kidneys fail to reabsorb the amino acid cystine, a protein building block, from the urine. Because the cystine is not properly filtered, it accumulates in the urinary tract and clumps together. This leads to the formation of painful crystalline deposits and stones in the bladder or kidneys.
Owners may notice blood in the urine, frequent straining to urinate, or recurrent urinary tract infections, typically starting in young to middle-aged dogs. Male dogs are at a higher risk of developing a complete, life-threatening blockage of the urethra.
While the underlying condition is lifelong and incurable, it is manageable with a specialized diet and regular veterinary monitoring. If a blockage occurs, emergency surgery is required to remove the stones, with overall treatment costs typically ranging from 1,500 to 7,000 EUR.
