[Value of isotopic cystography in the diagnosis of vesicoureteral reflux in childhood].

We have studied 62 children with urinary infection simultaneously by means of micturitional cystoureterography (MCU) and indirect isotopic cystography. We confirm a correlation between the results of the MCU and in the indirect isotopic cystography in 86% of the ureters explored, whilst the results of the MCU and of the direct isotopic cystography coincided in 92% of the ureters explored. We discuss the advantages and drawbacks of isotopic cystography, concluding that it is a suitable method for the diagnosis and evolutive control of vesicoureteral reflux in infancy.
