The purpose of this study was to establish the sensitivity of cyclic direct radionuclide cystography (RVC) in detecting vesicoureteral reflux (VUR) in infants and small children, and to compare it to the conventional (one cycle only) RVC. 428 patients (856 renal units) were admitted to the study from January 1991 through March 1992 and all had a cyclic RVC. The age of the patients ranged from 4 months to 7 years. The overall agreement of both cycles in detecting VUR in this study was 45%, the lowest being in detecting VUR I (36%), and the highest in detecting VUR III (86%). If we had used a conventional RVC (the first cycle only), 17 (29%) VUR I, 50 (36%) VUR II and 3 (9%) VUR III, which were detected in the second cycle only, would have been missed. We conclude that cyclic RVC detected 43% more VURs than the conventional (first cycle only) RVC, and would therefore recommend its use as a standard procedure instead of the conventional RVC.
本研究的目的是确定放射性核素膀胱造影术（RVC）检测婴幼儿膀胱输尿管反流（VUR）的敏感度，并将其与传统的（仅一个周期）RVC进行比较。1991年1月至1992年3月，428例患者（856个肾单位）纳入本研究，所有患者均接受了循环RVC检查。患者年龄范围为4个月至7岁。本研究中两个周期检测VUR的总体一致性为45%，检测VUR I时最低（36%），检测VUR III时最高（86%）。如果我们使用传统的RVC（仅第一个周期），那么仅在第二个周期检测到的17例（29%）VUR I、50例（36%）VUR II和3例（9%）VUR III将会漏诊。我们得出结论，循环RVC比传统的（仅第一个周期）RVC多检测出43%的VUR，因此建议将其作为标准程序使用，而非传统的RVC。
