Studies on 1,476 intravenous urographic examinations done in a 15-month period showed that the proportion of abnormal results varied widely-from 20% in patients with abdominal pain other than renal colic to 92% of those in prostatism. Patients with the strongest clinical evidence of haematuria were the most likely to have abnormal urograms, and to undergo cystoscopy with abnormal findings on this examination. All six patients with renal hypertension showed abnormalities other than on the urogram. Prior use of other tests may increase the effectiveness of urography.
对15个月内进行的1476例静脉尿路造影检查的研究表明，异常结果的比例差异很大——从非肾绞痛性腹痛患者中的20%到前列腺增生患者中的92%。血尿临床证据最明显的患者最有可能有异常的尿路造影结果，并且最有可能接受膀胱镜检查且在此检查中发现异常。所有6例肾性高血压患者除尿路造影外均有其他异常。先前使用其他检查可能会提高尿路造影的有效性。
