Gross bilateral reflux in infants: gradual decrease of initial detrusor hypercontractility.

Abstract

PURPOSE: 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. MATERIALS AND 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.
