Anuria (无尿症)
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.
Treatment
The most easily treatable cause is obstruction of urine flow, which is often solved by insertion of a urinary catheter into the urinary bladder.
Foley catheter
Prostatic stent
Bladder outlet obstruction
BOO is considered common. Men ages 50 to 60 have an 80% chance of having some degree of bladder outlet obstruction.
