COMPARISON OFDIRECT RADIONUCLIDE CYSTOGRAPHY (DRC) WITH CONTRAST VOIDING CYSTOGRAPHY (VCUG)IN CHILDREN WITH URINARY TRACT INFECTION

Cystography with contrast and cystography with radionuclide are two common methods
for diagnosis of urinary reflux. This study compared two methods, direct radionuclide cystography
(DRC) with contrast voidingcystography (VCUG).
Methods and materials: This study was conducted in 12 months and children with urinary tract
infection(age:2 month -15 years) whom referred to nephrology clinic were enrolled in the study. In
order to diagnosis the urinary reflux, one ofDRC and VCUG methods were performed randomly.Chisqure
and Descriptivetest was used for Data processing and statlstical Analysis.
Results: A total 135 children (270 ureter) were studied in this report. In 136 ureter,DRC and in 134
ureter VCUG were performed. Sex and age were matched in bath groups. VUR was detected in 66
ureter (%48.5) in DRC group and in 44 ureter (32.8) in VCUG group.StatisticallyDRC method was
more powerful in diagnosis of urinary reflux in comparison with VCUG method.
Discussion: In this study two methods had significant difference in diagnostic value. DRC method,
which was more sensitive in diagnosis of urinary reflux, was suggested to perform in observance of
ideal condition
