title: Hypercalciuria and recurrent urinary tract infections among children in Zahedan, Iran.
abstract: OBJECTIVE
  To evaluate the association of idiopathic urinary tract infection (UTI) and hypercalciuria in Iranian children.
  
  
  METHODS
  Seventy children with episodes of UTI, and 70 healthy controls were studied. Random urine calcium-creatinine ratio (UCa/Cr) and plasma calcium were measured.
  
  
  RESULTS
  Hypercalciuria was found significantly higher (p<0.05) in UTI patients (30%) than normal subjects (11.4%). The results showed that frequency of hypercalciuria is higher in females (42.9%) than males (17.1%).
  
  
  CONCLUSIONS
  The investigation of urinary calcium excretion in children with recurrent UTI is recommended.
