Abstract
PURPOSE: To determine if a negative renal sonogram is reliably predict ive of the absence of vesicoureteral reflux at voiding cystourethrogra phy (VCUG) in children aged 5 years or older. MATERIALS AND METHODS: I maging studies in 70 children aged 5 years or older who underwent rena l ultrasound (US) and VCUG on the same day were reviewed. These childr en had initially undergone evaluation because of a urinary tract infec tion. RESULTS: Five of 70 children had abnormal sonograms; two (40%) O f the five had reflux at VCUG. One had mild pelvicalyceal dilatation, and one had a small kidney. The other three (without reflux) had a pel vic kidney, a calyceal diverticulum, or a renal stone. Of 65 children with a negative sonogram, 19 (29%) had reflux at VCUG; 46 (71%) did no t. Altogether, of the 70 children, 21 had reflux, 19 (90%) of whom had no sonographic abnormality. CONCLUSION: Children with abnormal screen ing renal sonograms often have vesicoureteral reflux, but a normal son ogram does not reliably exclude the condition even in children aged 5 years or older. Therefore, VCUG must be performed even in older childr en, regardless of US findings, if clinical decisions are influenced by documentation of the presence of VUR.
