Related to Oliguria: anuria


Diminished excretion of urine.



a decrease in the daily quantity of excreted urine from the normal 1,500 ml to 500 ml. Oliguria results from reduced filtration or increased reabsorption in the kidneys. Physiological oliguria arises with dehydration, which can result from water deprivation, excessive perspiration, vomiting, or diarrhea. It may also accompany blood loss; extensive burns and traumas; a drop in arterial pressure, as in shock and collapse; or increased production of the hormones aldosterone or vasopressin. Oliguria is frequently a symptom of kidney disease, for example, nephritis.
