Vesicoureteral reflux in children

Vesicoureteral reflux is a common disease in children and is usually associated with urinary tract infections and renal scars. Renal damage associated with vesicoureteral reflux occurs secondary to renal maldevelopment during fetal life or renal infections in children and may produce hypertension, diseases in pregnancy and chronic renal failure. Bladder dysfunction may be responsible for persistent reflux and renal scars. In order to prevent renal damage, early diagnosis and prompt medical treatment or surgical correction are advised in a selected group of children. In the past all children with urinary tract infections were investigated with voiding uretrocystogram and received long-term antibiotic prophylaxis or surgery. In recent years several trials have provided information that suggest it is better to reduce the number of diagnostic and surgical procedures in children affected by vesicoureteral reflux.
