The Lack of Correlation Between Upper Tract Changes on Excretory Urography and Significant Vesicoureteral Reflux

Abstract

In a retrospective review of all excretory urograms and voiding cystourethrograms performed in a 1 yr period in 391 children evaluated with a history of urinary infection, 56 (14%) had vesicoureteral reflux as well as a normal excretory urogram. Of the 89 children in the study with vesicoureteral reflux, 56 (63%) had a normal excretory urogram. The grade of reflux was II or greater in 49% of the cases, which also had a normal excretory urogram. An excretory urogram without a voiding cystourethrogram is an inadequate study for a child with a history of urinary infection.
