Oliguria is the low output of urine. It is clinically classified as an output below 300-500ml/day. The decreased output of urine may be a sign of dehydration, renal failure, hypovolemic shock, multiple organ dysfunction syndrome, or urinary obstruction/urinary retention.

It can be contrasted with anuria, which represents an absence of urine, clinically classified as below 50ml/day.
