title: A new perspective on the natural history of vesicoureteric reflux.
abstract: Vesicoureteric reflux is most commonly recognized in girls after urinary tract infection. Increasing recognition of vesicoureteric reflux in neonates, detected after an abnormal prenatal sonogram, shows a marked male predominance: 80% boys. Vesicoureteric reflux in children may be both a congenital abnormality, more common in boys, and an acquired abnormality, more common in girls with voiding dysfunction.
