The detection or exclusion of vesico-ureteral reflux (VUR) has classically been by micturating cystourethrography (MCUG). Radionuclide cystography will detect VUR but fails to provide the same detailed anatomical informations as MCUG. This study allowed a comparison of indirect radionuclide cystography (IRC) and MCUG in 65 children. Renal reflux was detected by IRC in 32% of renal units, while VUR was seen in 36% by MCUG. When a comparison was made with MCUG, IRC had a sensitivity of 74.1% and a specificity of 90.5%. The markedly reduced radiation dose, avoidance of a bladder catheter plus the ability to monitor the urinary tract constantly during the entire procedure should ensure that IRC is the examination of choice in follow-up studies for VUR in all toilet-trained children.
传统上，膀胱输尿管反流（VUR）的检测或排除是通过排尿性膀胱尿道造影（MCUG）来进行的。放射性核素膀胱造影能够检测出VUR，但无法提供与MCUG相同详细的解剖信息。本研究对65名儿童的间接放射性核素膀胱造影（IRC）和MCUG进行了比较。IRC检测出32%的肾单位存在肾反流，而MCUG检测出36%存在VUR。与MCUG相比，IRC的灵敏度为74.1%，特异性为90.5%。辐射剂量显著降低、无需插入膀胱导管以及在整个检查过程中能够持续监测尿路，这些因素应确保IRC成为所有已接受如厕训练儿童VUR后续研究中的首选检查方法。
