Cystinuria is an inherited autosomal recessive disorder and is characterized by the formation of cystine stones in the kidneys, ureter, and bladder.

Causes

Cystinuria is characterized by the inadequate reabsorption of cystine during the filtering process in the kidneys, thus resulting in a excessive concentration of this amino acid. Cystine will precipitate out of the urine, if the urine is neutral or acidic, and form crystals or stones in the kidneys, ureters, or bladder.

Occurrence in other Animals

Newfoundland dogs are at an increased risk to cystinuria, compared with other breeds of dogs.
