title: Renal arterial stenosis and circadian water and sodium excretion in subjects with a reduced fluid intake.
abstract: Circadian water and sodium excretion in patients with renal arterial stenosis is inverted, but if the fluid intake is reduced it can return to normal. The findings also furnish indirect evidence that changes in circadian water and sodium excretion in patients with renal arterial stenosis are related to the degree of hydration of the organism. When evaluating circadian water and sodium excretion in patients with renal arterial stenosis, the osmolarity (specific gravity) of the urine should thus be taken into account.
