Detailed Description:
  1. To investigate the outcome of melamine-related-calculus.

    • The change of calculus.
    • The change of obstruction features,including hydronephrosis and ureterectasia.
    • The change of the urinalysis.
  2. To investigate the change of renal function in children with melamine-related-calculus during the follow up.

    • Creatinine, urea and uric acid.
    • α and β2 microglobulin.
