title: [Pollakiuria and idiopathic hypercalciuria in childhood].
abstract: OBJECTIVE
  To determine the incidence of pollakiuria in children with idiopathic hypercalciuria.
  
  
  METHODS
  The clinical records of 56 children with idiopathic hypercalciuria were reviewed. In addition to pollakiuria, they were evaluated for other associated disorders, maximum urinary osmolality, urodynamic study and overall clinical course.
  
  
  RESULTS
  Nine children (16%), 4 boys and 5 girls, presented with pollakiuria associated with urgency, nocturnal enuresis, hematuria and urinary incontinence. Two showed normal urodynamic studies and unstable bladder was observed in another case. All but one patient preserved normal renal concentration capacity. The course of the micturition symptoms was satisfactory and only three cases required pharmacological treatment.
  
  
  CONCLUSIONS
  In the absence of urinary infection, pollakiuria might suggest the presence of hypercalciuria, a condition that can be managed successfully following correct diagnosis and treatment. Renal concentration capacity is not reduced by hypercalciuria.
