Prevalence of hydronephrosis and vesicoureteral reflux in pediatric urinary tract infection

Abstract We studied 108 children diagnosed with urinary tract infection (UTI) to determine the frequency of hydronephrosis and vesicoureteral reflux (VUR). Fifty-two children (48.1%) had hydronephrosis (pyeloureteral junction obstruction: 27.8%) and 43 children (39.8%) had VUR (primary VUR: 36.1%). A renal scar was seen in 25.8% of the VUR cases. We recognized again that children with a history of UTI need to be examined promptly and thoroughly.
