To evaluate voiding cysto-urethrography (VCUG) in assessing children with urinary tract infection (UTI) when renal/bladder ultrasonography and renal scintigraphy show no abnormality.


A total of 468 renal scintigrams taken in children for an indication of UTI between January 1996 and December 1998 were reviewed. The renal and bladder ultrasonograms of those children with a normal renal scan were then reviewed. Children with both normal renal scans and normal ultrasonography were then evaluated for the frequency and grade of vesico-ureteric reflux (VUR) on VCUG.


Of the 468 patients, 453 (97%) had complete imaging studies; 152 of the children evaluated had normal renal scans, of whom 101 had a normal renal ultrasonogram. Twenty-three (23%) children with both a normal renal scan and renal/bladder ultrasonogram showed VUR on VCUG, of whom 14 had bilateral VUR and 13 grade III or higher VUR.


This study indicates that about 23% of patients may have significant VUR despite both a normal renal scan and ultrasonogram. Therefore, VCUG remains important in evaluating and managing children with UTI.
