38 hypertensive patients suspected of renovascular hypertension were examined with rapid sequence urography, washout, aortography or selective renal arteriography. When discordant results were found between rapid sequence urography and washout, we used a particularly helpful procedure which we define reinjection or rapid sequence urography after washout: washout is followed by the injection of a second 50-cm3 dose of contrast agent and five more roentgenograms at 1-min intervals. In our series, reinjection allowed correct diagnosis in 66% of the cases with discordant results and confirmed diagnosis in 83% of the cases of renovascular hypertension.
对38例疑似肾血管性高血压的高血压患者进行了快速序列尿路造影、洗脱试验、主动脉造影或选择性肾动脉造影检查。当快速序列尿路造影和洗脱试验结果不一致时，我们采用了一种特别有用的方法，即洗脱后再注射造影剂或快速序列尿路造影：洗脱后注射第二剂50立方厘米造影剂，然后每隔1分钟再拍摄5张X光片。在我们的系列研究中，再注射使66%结果不一致的病例得到了正确诊断，并使83%的肾血管性高血压病例确诊。
