Eighty intravenous pyelograms, carried out as part of the routine investigation of hypertension, revealed only one unsuspected renal lesion of possible relevance to the long-term management. Such a low therapeutic return, in the light of its cost and not entirely negligible risk, raises doubts about the place of excretion urography amongst the screening tests aimed at discovering tractable underlying causes of hypertension.
作为高血压常规检查的一部分，进行了80次静脉肾盂造影，结果仅发现1例与长期治疗可能相关的隐匿性肾脏病变。鉴于其成本和并非完全可忽略的风险，如此低的治疗回报让人对排泄性尿路造影在旨在发现可治疗的高血压潜在病因的筛查测试中的地位产生怀疑。
