In practical terms the frequency of renovascular hypertension can only be measured from groups of hospitalized hypertensives, in which severe forms and young subjects are over-represented, thus leading probably to an overestimate. Using a group of 1 009 consecutively hospitalized hypertensives, the frequency of renovascular hypertension was measured in 18 subgroups defined by sex, age (three classes) and blood pressure (three classes). For each subgroup the specific rate was then multiplied by the prevalence of the corresponding category in the population of unselected 20-64 years old hypertensives. This method led to the following conclusions: about 2% of the unselected hypertensives would be candidates for surgical correction of renovascular hypertension and 0.5% would be cured.
实际上，肾血管性高血压的发病率只能通过住院高血压患者群体来衡量，而这些群体中重症患者和年轻患者占比过高，因此可能导致高估发病率。通过对1009例连续住院的高血压患者进行研究，根据性别、年龄（三个年龄段）和血压（三个级别）将其分为18个亚组，分别测量肾血管性高血压的发病率。然后，将每个亚组的特定发病率乘以未选择的20至64岁高血压人群中相应类别疾病的患病率。通过这种方法得出以下结论：在未选择的高血压患者中，约2%适合接受肾血管性高血压的手术矫正，0.5%可以治愈。
