Urinary tract infection (UTI) remains a public health problem since its incidence is still high in the pediatric age group. In addition, some patients with UTI develop progressive renal parenchymal damage, mainly those cases associated with obstructive uro-pathy or vesicoureteral reflux (VUR). The prognostic signficance of renal parenchymal damage is emphasized by the fact that in 20 to 50% of uremic children the primary cause of chronic renal failure is chronic pyelonephritis (1, 2). In our experience, chronic pyelonephritis is seen only in cases with UTI and obstructive uropathy or VUR, as will be shown below.
