title: The prevalence of hypercalciuria in girl kids with over active bladder.
abstract: BACKGROUND
  Hypercalciuria may be a sign of over active bladder, these symptoms may be treated if we get rid of hypercalciuria.
  
  
  OBJECTIVE
  This paper is intended to get to the prevalence of hypercalciuria in girl kids with over active bladder.
  
  
  METHODS
  All patients with index of over active urinary bladder who admitted to Amir-Kabir hospital of Arak and children who have admitted without any particular disease just for a laboratory check were studied simultaneously. Urine sample was taken from both groups.
  
  
  RESULTS
  The prevalence of hypercalciuria in the group with normal urinary bladder was 22.6% and in the case group was 42.9%. Hypercalciuria was reported in 30 (22.6%) children of control group and 57 (42.9%) children of case group. Based on chi-square test, hypercalciuria distribution between the two groups is not homogeneous (P = 0.001). Mean calcium to creatinine ratios were 2.384330 ± 0.55694 (mg/mg) and 2.186552 ± 0.56714 (mg/mg) for control and case groups respectively and no significant difference is observed between the two groups (P = 0.976). Based on logistic regression test, there is a significant relationship between both case and control groups and the occurrence of hypercalciuria with 2.58 times more than control group observed in case group.
  
  
  CONCLUSIONS
  Based on the high prevalence of hypercalciuria in case group, examination and treatment of hypercalciuria in patients with over active bladder may be effective.
