Abstract :

Objectives– To compare the diagnostic accuracyof direct radionuclide cystography as compared to voiding cystourethrography in detection of vesicoureteric reflux diseases.

Material and methods–A prospective, cross–sectional study that enrolled 54 children (108 renal units) was performed.Specific statistical parameters in detecting and grading VUR with a DRCG were calculated.

Results– DRCG detected 22 of the 32 renal units that had VUR on the VCUG. It had a sensitivity of 69 %, specificity of 100 %, positive predictive value of 100% , negative predictive value of 88 %, accuracy 91% and Coefficient of Agreement – Kappa of 0.76 ( highly significant ) in detecting VUR as compared to VCUG.

Conclusion–DRCG compared modestly with VCUG in detecting VUR. A voiding study is suggested to improve the sensitivity.
