Primary aldosteronism (PA) has a prevalence of about ten percent in a hypertensive population and is an important risk factor for cardiovascular disease. The aldosterone to renin concentration ratio (ARR) is an established diagnostic tool in the screening for PA. However, hormonal determinations are time-consuming and expensive. Therefore, we studied the value of the sodium to urinary sodium to potassium to urinary potassium (SUSPUP) ratio in 37 patients with PA, in 34 hyperte...

A patient was referred to us because he had hypokalemic hypertension and no detectable blood concentrations of renin and aldosterone. In addition, this patient had an adrenal mass. Since he was hyponatremic, he was put on fludrocortisone.At presentation, we found that the patient was normonatremic and hypokalemic and had a high sodium to urinary sodium to potassium to urinary potassium (SUSPUP) ratio. But review of older laboratory results showed an inad...
