Cystinuria is a disorder characterized by cystine stones in the
kidney, ureter, and bladder. A genetic abnormality results in
abnormal transport of amino acids in the kidney. The high levels of
the amino acid cystine in the urine lead to stone formation. While
this disease only accounts for 1-2 % of urinary tract stones in the
general population, it is the most common cause among children.
