[Bilateral stenosis of the renal arteries with normal urography (author's transl)]

In theory, negative urographic findings in severe hypertension exclude a renovascular origin. However, when both renal arteries are dysplastic urography may remain perfectly normal even though arteriography demonstrates tight stenoses and these patients are cured by surgical treatment. In the case reported here the only clinical sign of stenotic renal arteries was a systolic murmur on auscultation of the abdomen.
