diuresis (redirected from cold diuresis)

diuresis /di·ure·sis/ (di″u-re´sis) increased excretion of urine.

osmotic diuresis  that resulting from the presence of nonabsorbable or poorly absorbable, osmotically active substances in the renal tubules.

pressure diuresis  increased urinary excretion of water when arterial pressure increases, a compensatory mechanism to maintain blood pressure within the normal range.

diuresis

[dī′yoo͡rē′sis]

Etymology: Gk, dia, through, ouron, urine

increased formation and secretion of urine. Diuresis occurs in conditions such as diabetes mellitus, diabetes insipidus, and acute renal failure. It is normal in the first 48 hours after giving birth. Coffee, tea, certain foods, diuretic drugs, anxiety, fear, and some steroids cause diuresis. Water is considered the least expensive diuretic.

cold diuresis

occurs in hypothermia as a result of peripheral vasoconstriction, hyperglycemia and decreased renal tubular absorption.

osmotic diuresis

due to increased concentration of solutes which are not reabsorbed in the proximal tubules and which, by osmotic pressure, cause water to be retained. See also osmotic diuretic.

postobstruction diuresis

due to the diuretic effect of urea and electrolytes retained during the period of obstruction.

water diuresis

ingestion and excretion of an excess of water, without a corresponding amount of sodium; involves expansion of plasma volume, increased left atrial pressure and inhibition of ADH. See also obligatory water diuresis.
