مقایسه سیتوگرافی رادیونوکلوئید مستقیم (DRC) و سیستوگرافی با ماده حاجب (VCUG) در تشخیص رفلاکس ادراری مثانه به حالب (VUR) در کودکان مبتلا به عفونت ادراری

 Background & Aims: 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). Materials & Methods: This study was conducted for 12 months on children with urinary tract infection )age: 2 months-15 years) whom referred to nephrology clinic were enrolled in the study. In order to diagnose the urinary reflux, one of DRC and VCUG methods was performed randomly. Chi-square and Descriptive test was used for data processing and statistical analyses.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 both groups. VUR was detected in 66 ureter (%48.5) in DRC group and in 44 ureter (32.8) in VCUG group. Statistically, DRC method was more powerful in diagnosis of urinary reflux in comparison with VCUG method.Conclusion: 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.SOURCE: URMIA MED J 2013: 24(8): 606 ISSN: 1027-3727
