cystine kidney stones
Kidney stones formed
due to an excess of cystine in the urine. Small stones
are passed in the urine, but big stones remain in the
kidney, impairing the outflow of urine. Medium-size
stones can make their way from the kidney into the
ureter and lodge there, further blocking the flow of
urine. See also 
cystinuria.
