Renal vein renin activity

Bilateral renal vein renin activity measurement refers to measuring the ratio of renal renin activity on both sides (ipsilateral renin / contralateral renin, RVRR) and peripheral circulating renin levels or on the opposite renal renin and surrounding The ratio of blood renin. It is generally believed that when the peripheral blood renin activity is high and the difference in the renal venous renin activity on both sides is greater than 2 times, the surgical effect is good. Kaufman reports an effective rate of 93%.
