Diagnosis and Treatment of Primary Hyperaldosteronism

Abstract

Of the 51 patients with primary aldosteronism who had adrenalectomy (43 patients with adenomas and 8 with hyperplasia), those most likely to be cured were younger and had lower plasma renin activity. In patients with adenomas who were cured or improved, aldosterone secretion was more likely to lateralize. Tests that distinguished adenomas from adrenal hyperplasia included the postural stimulation test, urinary excretion rates of 18-oxocortisol and 18-hydroxycortisol, and adrenal vein sampling.
