The advantages of radionuclide method are minimal radiation dose and possibility attentively track whole process of filling and empting a bladder. We evaluate the diagnostic value of direct radionuclide cystography in comparing with “gold standard” - micturition cystourethrography (MCUG) in the detecting of the grade of vesicoureteral reflux (VUR) METHODS 150 children in the age of from 3 month to 14 years with VUR were detected by both methods - direct radionuclide cystography and MCUG. Imaging parameters, which were described by direct radionuclide cystography, includes volume of bladder when VUR occurs, duration of VUR and its activity. Activity of VUR was measured as a relevance quantity of nuclear tracer in ureter comparing to its activity in bladder RESULTS VUR grade 4 was found in 22 children. On direct radionuclide cystography, it was characterized by active VUR, when the activity in ureter was more than 15% comparing the activity in bladder. In 10 cases, it occurs on the small bladder volume less than 50% of effective volume, in others the bladder volume was 50–70%. There were prolonged VUR more than 120sec.in all cases. VUR grade 3 was detected in 40 children by MCUG. On radionuclide method, it was completely confirm in all patients. Its activity in 15 of them was 2,5%-5% with bladder volume less 50% from effective, in 10 5–7,5% on bladder volume above 50% from effective volume, in 15 there was 8–10% activity on bladder volume 60–80% from effective one. Duration of VUR was very different, from 10sec. until 110sec. Among 98 children where the radionuclide cystography found VUR activity less than 3,5% on the bladder volume near effective (80–100%) with it different duration MUCG confirm VUR grade 2 in 40 and VUR grade 1 in 45, in others 13 cases VUR was not confirm by roentgen cystography CONCLUSIONS direct radionuclide cystography is effective method not only for detecting VUR, as well to describe its grade. Activity of nuclear tracer in ureter comparing its activity in bladder significant describe the grade. Bladder volume when the VUR occurs is the indirect indication. Moreover, the duration of VUR does not describe its grade. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e183-e184 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Zukhra Sabirzyanova More articles by this author Andrey Pavlov More articles by this author Dmitry Fomin More articles by this author Gevorg Simonyan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
