The conservative management of vesicoureteric reflux: a review of 121 children.

A group of 121 children with vesicoureteric reflux (VUR) grades 1 to 3 managed conservatively were followed-up for a period of six to ten years. In the majority of patients VUR grades 1 and 2 disappeared spontaneously. Prognosis was less favorable in those who were seen initially with grade 3 VUR. A statistically significant higher incidence of reflux disappearance was observed in children who were seen before 4 years of age. In the majority of patients with paraureteric-vesicle diverticulum, reflux persisted. Reflux was more likely to disappear in children with lower incidence of urinary tract infection than in those with multiple infections.
