Reflux and voiding abnormalities in children.

Twenty-four patients with vesicoureteral reflux were studied urodynamically because of a history of dysfunctional voiding. Nine patients eventually had antireflux surgery. The remaining 15 patients were followed from two to six years. These patients were managed conservatively with an emphasis on controlling infection and improving voiding habits. Reflux resolved spontaneously in 12 patients and improved in 1 patient. Dysfunctional voiding is a definite cause of childhood reflux. Treatment should be directed at improving voiding patterns. Coordinated voiding may allow a child to "grow out" of his reflux.
