The natural history of vesicoureteral reflux in children is well documented. In most series girls comprise the majority of the children followed. We reviewed the presentation and course of 86 boys with primary vesicoureteral reflux to define the nature of reflux in that selected population. Of the boys 25 per cent presented when they were less than 3 months old and the youngest tended to have the most severe reflux. Presentation was usually with urinary tract infection but 14 per cent had dysfunctional voiding symptoms without urinary tract infection. Based upon their presentation and initial evaluation the patients were allocated to 1 of 3 treatment protocols: observation, chemoprophylaxis or surgery. No renal parenchymal loss was detected in the boys on observation. Surgical therapy was free of serious complications. Over-all, this modified approach to the management of reflux in boys is acceptable although further followup will be required to confirm these initial conclusions.
