The Comparison of Indirect Radionuclide Cystography (IRC) and Voiding Cystourethrography (VCUG) in Diagnosing

Introduction: Vesico-Urethral Reflux (VUR) is the most common complication of Urinary-Tract Infection (UTI). Detecting VUR has been classically achieved by Voiding Cystourethrography (VCUG). Radionuclide cystography will detect VUR, but fails to provide the same detailed anatomical information as VCUG. This study designed to compare the IRC and VCUG. Materials & Methods: This study has been done on 55 patients suffering from UTI admitted in Razi Hospital of Kermanshah during 2001-2. They were evaluated by two methods (VCUG and IRC), which were performed apart from each other during one month for each patient. Results: From 55 patients 69% were females and 30.9% were males. The age range of patients was 6 months to 13 years. From 109 renal units VUR was detected by cycling IRC in 29 patients (26.4%) while in 15 patients by VCUG (13.9%). Conclusion: The result of this study indicated that IRC had a higher sensitivity in comparison with VCUG technique. So it is recommended that the IRC Method be used in diagnosing Vesico Urethral Reflux.
