Urography was performed in 250 patients: the technique of bolus injection of a large quantity of contrast medium was used in every case. By means of rapid seriography the early vascular phase was shown and reproduced, when necessary, with image subtraction. The abdominal aorta and the renal arteries were demonstrated in 97.6% of cases. Altogether, in 34.4% of cases the existence of pathological conditions non demonstrable by conventional urography was ascertained; in 12.4% of cases extrarenal pathology was diagnosed. This technique is suggested to be used sistematically, as an alternative to DSA, where digital equipments are not available.
对250例患者进行了尿路造影：每例均采用大剂量造影剂团注技术。通过快速连续摄影显示早期血管相，并在必要时采用图像减法进行再现。97.6%的病例显示了腹主动脉和肾动脉。总共，在34.4%的病例中确定存在常规尿路造影无法显示的病理状况；在12.4%的病例中诊断出肾外病变。建议系统地使用该技术，作为在没有数字设备时替代数字减影血管造影（DSA）的方法。
