title: [The clinician's need in renovascular hypertension].
abstract: Clinician questions in nephrovascular hypertension are: 1) Is hypertension secondary to nephrovascular disease? 2) Is vascular obstruction susceptible of surgical management? 3) Which is the best technical approach? In this review of recent international literature we have focused diagnostic value of echo-color Doppler in the screening of patients with secondary hypertension. The sensibility and specificity of this diagnostic test reach 89% and 99.5%. Respectively when the stenosis is over 70%. Anyway when the stenosis is under 70% the accuracy of this examination is lower. Angiography remains the gold standard test in patient eligible for surgery, although its invasiveness. Diagnostic tests of the renin-angiotensin axis (e.g. Captopril test) are useful too, but morphologic evidence is not provided. Surgical approach is the best choice in elective patients.
