Reliability of voiding cystourethrography to detect reflux

1989

The purpose of this study was to establish the reliability of VCUG by repeating the VCUG and comparing the results of a consecutive second and/or third cyclic filling and voiding to the first.

• “Retrograde voiding cystourethrography (VCUG) with contrast medium came into widespread use around 1958, when fluoroscopes with image intensification and cine recording became generally available.”

• “22 out of 177 patients had a discrepancy in the results between two cycles.”

• “By no means do we advocate multiple fillings in all children.”

• “To select patients who might benefit from cyclic voidings, we suggest that in children with urinary tract infection a sonogram be obtained before VCUG.”
