title: The frequency and frequency dysuria syndromes of childhood: hypercalciuria as a possible etiology.
abstract: OBJECTIVE
  The syndromes of frequency and frequency dysuria of childhood are believed to have multifactorial etiologies. Hypercalciuria has been reported to be associated with the frequency dysuria syndrome and a direct cause and effect relationship has been postulated due to a positive response to treatment with hydrochlorothiazide. This study was designed to compare the urinary calciums of children with the frequency syndrome and the frequency dysuria syndrome.
  
  
  METHODS
  Calcium screening in 30 consecutive patients with the frequency syndrome and 39 consecutive patients with the frequency dysuria syndrome is reported.
  
  
  RESULTS
  There was no statistical difference in the urinary calcium excretion in the two groups.
  
  
  CONCLUSIONS
  There was no significant difference in the calcium excretion in children with isolated urinary frequency or frequency dysuria. No definite cause and effect relationship to hypercalciuria could be identified in these two groups.
