The hunt for renal hypertension.
The proportion of cases of hypertension with a renal cause which can be corrected by surgery is very small. Radiological diagnosis of such a cause is expensive and time-consuming; hence the rewards of intensive investigation are small compared with the cost. Measurement of plasma-renin offers a good method of selecting those patients who require further investigation, if the cut-off point is carefully considered in the light of the acceptable incidence of false-positive and false-negative results.
