Measurement of Renal Vein Renins or Differential Renal Function Studies in the Diagnosis of Curable, Renovascular Hypertension?
We have used both differential renal function studies and measurements of plasma renin activity in the evaluation of our hypertensive patients during the past few years. Using the renin method of Boucher(1), and the technique of differential function studies described earlier(2,3), we can make the following general comparisons:
The advantages of measurement of renal vein renins over differential function studies are that (a) samples can be collected with relative ease and safety and (b) renin determinations are the only way to asscess the significance of unilaterally small kidneys with parenchymal disease but normal main renal arteries.
