diuresis

   Also found in: Dictionary/thesaurus, Wikipedia, Hutchinson 0.06 sec.
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.

di·u·re·sis (d-rss)
n.
Discharge of urine, especially in unusually large amounts.

diuresis,
n increase in urine production and passage from the body occurring in conditions such as diabetes mellitus and diabetes insipidus.

diuresis
increased excretion of the urine.

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.

Clinical trials using sodium bicarbonate suggest that alkalising the diuresis helps prevent acute renal failure (ARF) in myoglobinuria, by preventing the breakdown of myoglobin into a substance toxic to the proximal tubules (Cunningham 1997).
Although all urinary parameters were adjusted for CreatU, we performed multiple regression analyses by again testing CreatU levels to eliminate any residual effect of the diuresis.
Intracranial pressure is reduced by hyperventilation, supplemented if necessary by mannitol diuresis or by the release of CSF through a tiny hole created in the temporal dura.
