From the word itself, you can derive its definition. The prefix “a-“ or “an-“ means absence. Uria refers to urine. So by the context of the word, anuria or anuresis means no urination.
But in the clinical setting, this is actually not the case. Medically, anuria means having a urine output of less than 100 mL per day. The kidneys do not totally stop producing urine. If the kidneys stop functioning, the person dies.
The term anuria was coined in order to denote that the urine output is dangerously low. If untreated, it can be a cause of death.
Anuria is almost always associated with the term oliguria. Oliguria means having a urine output of less than 500 mL per day. It is an early sign of kidney problems. Anuria comes in late, when the disease progresses and if it is in its advanced state. Obviously, anuria is worse than oliguria.
Prerenal causes of anuria refer to problems of the structures “before the kidneys,” i.e. the blood vessels that supply the kidneys.
The kidneys are very vascular organs, especially its medullary part. If the blood supply to the kidneys is low, it means other organs are in dire need of blood and oxygen supply, hence, the kidney which is an organ of elimination, receives less.
Decreased renal perfusion or mean systemic arterial pressure decreases renal output via autoregulatory mechanisms and neurohumoral pathways.
