Considerable interest persists in renovascular lesions amenable to surgical correction. In 1939, Blackman, describing the postmortem findings in 50 cases of essential hypertension,1 found sclerotic plaques projecting into the renal arteries in 86%. It is difficult, however, to obtain statistically significant data of the frequency of renal arterial disease in the hypertensive man because (1) not all hypertensive patients are subjected to the gamut of screening tests, and (2) the suspected cases show a relatively high percentage of positive findings. Thus, in a series of 427 patients studied at the Cleveland Clinic, 131 occlusive renal lesions were discovered.2
In the past decade, several major proposals have appeared for recognition of the ischemic kidney. A searching analysis of these methods, together with novel proposals for screening and confirmatory evidence of unilateral or bilateral renal ischemia, has been described by Stamey and associates.3 Bilateral ureteral catheterizations were performed with
