title: Gross bilateral reflux in infants: gradual decrease of initial detrusor hypercontractility.
abstract: OBJECTIVE
  We performed followup investigations of the urodynamic patterns of 11 boys with gross bilateral reflux, which are sometimes characterized by low bladder capacity and hypercontractility of the detrusor.
  
  
  METHODS
  Urodynamic evaluations were done a mean of 2 years after the initial assessment during infancy.
  
  
  RESULTS
  Initial hypercontractility resolved and bladder capacity increased from below normal to high in the majority of cases. The number of children with instability did not change significantly.
  
  
  CONCLUSIONS
  The urodynamic pattern at followup was similar to that previously reported as the most common dysfunction in older children with reflux.
