What causes anuria?

Anuria is when your kidneys don’t have enough blood or fluid supply from conditions like extreme dehydration, blood loss, severe infection, shock, or heart and liver failure. Anuria can also be caused by something affecting your kidney’s normal filtering of your blood. Some of those causes include severe shock, infections, some medications, intoxication and autoimmune diseases. Ultimately, anuria can be caused by obstruction or abnormalities in the normal urine flow after the blood has been filtered and processed by the kidneys. These post-renal causes include bladder outlet obstruction, kidney stones or an enlarged prostate gland.
