Which term is used to describe scanty urine output?

The term used to describe scanty urine output is "oliguria." Oliguria refers specifically to a reduced urine output, typically defined as less than 400 milliliters per day in adults. This condition can be indicative of various underlying issues, including dehydration, kidney dysfunction, or urinary obstruction.

In contrast, anuria refers to a complete absence of urine output, which is more severe than oliguria. Polyuria is the condition characterized by an excessive amount of urine output, usually exceeding 2.5 liters per day. Nocturia involves the need to wake up during the night to urinate and does not relate to the volume of output during the day.

Understanding these terms is critical in clinical practice, as they help healthcare providers assess kidney function and fluid balance in patients.
