title: Utility of CT Scan in detection of melamine--associated urinary stones.
abstract: OBJECTIVE
  To detail the utility of CT scan in detection of urinary stones induced by melamine tainted formula.
  
  
  METHODS
  A total of 1062 children fed with melamine-contaminated infant formula were screened for urinary stones in our institute from September through December 2008. Ultrasonography of the urinary tract system was performed in all these children. If the children with suspected stones or severe obstruction were presented after ultrasound examination, the multi-detector row CT urographic examination was advocated subsequently.
  
  
  RESULTS
  Ultrasound examination in combination with multi-detector row CT urography could increase the diagnostic rate from 3.4% (36/1062) by ultrasound examination alone to 4.6% (49/1062).
  
  
  CONCLUSIONS
  The specificity and sensitivity of the multi-detector row CT urographic examination is higher than ultrasonography.
