ABSTRACT
Purpose: This study was performed to assess necessity of voiding cystourethrography (VCUG) for infants with urinary tract infection (UTI) who had both normal renal sonography and normal DMSA renal scans.
Methods: We reviewed 117 infants hospitalized for UTI between February 2002 and July 2007 at Sanggye Paik Hospital. The diagnosis of UTI was made by culture from a urine specimen obtained by suprapubic puncture(n=57), catheterization(n=58), or collection bag method (n=2, twice positive culture of the same organism). All patients had undergone renal sonography, DMSA renal scan and VCUG. Children with both normal renal sonography and normal DMSA renal scans were evaluated for the presence or severity of vesicoureteral reflux (VUR).
Results : Of the 117 patients, 96 were boys and 21 were girls. 28 patients(23.9%) had VUR. 59(50.4%) showed both normal renal sonography and normal DMSA renal scans. Among these 59 patients, 7(11.9%) showed VUR. Three of them had grade I-II reflux, two grade III reflux, and the other two grade IV reflux. One of them showed bilateral VUR, grade IV reflux on the right and grade III on the left.
Conclusion : Although the negative predictive value of both normal renal sonography and normal DMSA renal scan for VUR was 88.1%, 7 patients had VUR and two of them had high grade reflux(grade IV). So, we suggest that VCUG should be performed in infants with UTI despite both normal renal sonography and normal DMSA renal scans.
