Methods Data of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children’s Hospital affiliated to the Capital Medical University and the Xuzhou Children’s Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, image features as well as effects of 4 types of therapies. Results All the 34 infants with urinary calculus were plicated with acute renal failure, their blood urea nitrogen (BUN) was ()mmol/L and creatinine (Cr) was ()μmol/L. The chemical analysis on the urinary calculus sampled from 14 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was () d for cy
