The renal blood flow/renal mass relation in renovascular hypertension.

A new concept is established in the etiopathogenic mechanism of renovascular hypertension. After performing two stenoses of the renal artery, according to Goldblatt's method, with an interval of 5 months between each, it is noted that the variations in the figures for arterial blood pressure depends directly on the reduction of renal mass. This is backed up by reninemia and pathological anatomy. With this, the concepts of static or dynamic stenosis of the renal artery are pinpointed.
