Comparative Study of Color Doppler Voiding Urosonography Without Contrast Enhancement and Direct Radionuclide Voiding Cystography for Diagnosis of Vesicoureteric Reflux in Children

摘要

Most available studies investigating the diagnostic accuracy of color Doppler voiding urosonography in the detection of vesicoureteric reflux used an echo contrast agent. It is unknown whether echo contrast agents are necessary for diagnosis or follow-up of vesicoureteric reflux. We compared color Doppler voiding urosonography without contrast enhancement and direct radionuclide voiding cystography in the detection and grading of vesicoureteric reflux with respect to the sex and age of patients as well as the severity of reflux.
