title: [What information can radiodiagnostic media give us when recurrent urinary infections in childhood are caused by functional pathology and anatomic anomalies?].
abstract: OBJECTIVE
  To analyze the alterations of the radiologic studies in children with recurrent urinary tract infection without urinary tract organic abnormalities.
  
  
  METHODS
  The present study comprised 50 children (8 boys, 42 girls) aged 4 to 36 months (mean 16 months). Patient evaluation included diagnostic voiding cystourethrogram, ultrasonography and intravenous urography.
  
  
  RESULTS
  Voiding and filling cystourethrography were performed in all cases, which demonstrated a trabeculated bladder (like fringes in the bladder wall); 35 of the 50 children had small bladders; 15 of the 50 children had a normal or bigger, but flaccid bladder. Forty-four children showed signs of intermittent obstruction in the posterior urethra during the voiding phase. The intravenous urogram showed a small bladder with different degrees of trabeculation and residual urine in 15 of 38 cases.
  
  
  CONCLUSIONS
  Radiologic diagnostic studies can discard organic abnormalities of the urinary tract and can be useful un detecting a possible functional disorder.
