Abstract. Osmotic diuresis occurs, if nonreabsorbed solutes such as mannitol impair the reabsorption of water. The reduced reabsorption of volume affects in turn the reabsorption and excretion of solutes. Thus, mannitol leads to modest impairment of proximal tubular reabsorption not only of water, but as well of electrolytes

Most diuretics produce diuresis by inhibiting the reabsorption of sodium at different segments of the renal tubular system. Diuretic use in clinical practice spans conditions like edema, hypertension, metabolic acidosis and hyperkalemia. Patients with nephropathy or heart failure may have a 10 to 30% increase in extracellular.
agents which induce a loss of body fluid by increasing the urinary excre- tion. The term “ diuresis " is usually qualified “ water diuresis," “ salt diuresis," “ mercurial diuresis," etc.. in which cases reference is made to the specific diuretic agent or drug used irrespective of whether there is a decrease of the volume of body fluid or
2 Aug 2011 Abstract. Background. Hypernatraemia is common in critically ill patients and has been shown to be an independent predictor of mortality. Osmotic urea diuresis can cause hypernatrae- mia due to significant water losses but is often not diag- nosed. Free water clearance (FWC) and electrolyte free.

The practitioner who is armed with the knowledge of the mechanism of action of diuretic drugs and with ap- propriate recognition and respect for their potential side effects can use these compounds with a high degree of efficacy and safety.

10 Dec 2015 Polyuria, defined as daily urine output in excess of 3.0 to 3.5 L/d, can occur due to solute or water diuresis. Solute-induced polyuria can be seen in hospitalized patients after a high solute load from exog- enous protein administration or following relief of urinary obstruction. Similar clinical scenarios are
Mechanism of osmotic diuresis. Mannitol might inhibit para- cellular reabsorption of water and sodium chloride in the proxi- mal tubules by reducing the osmotic driving force. We examined this hypothesis in anesthetized dogs. Bicarbonate reabsorption was kept constant by sodium bicarbonate infusion, and trans-.

Technically, the term "diuresis" signifies an increase in urine volume, while "natriuresis" denotes an increase in renal sodium excretion. Because natriuretic drugs almost always also increase water excretion, they are usually called diuretics. Many diuretic agents (loop diuretics, thiazides, amiloride, and triamterene) exert
