Oliguria Defined: Understanding Low Urine Output
Oliguria is a medical term that signifies a reduced volume of urine excretion over a specified period, typically 24 hours. It is a crucial indicator of kidney function and hydration status.
Key Definition
Oliguria is specifically defined as the excretion of less than 300 ml of urine in a 24-hour period. This contrasts with:
- Anuria: Complete absence of urine production (typically < 50 ml/day).
- Normal urine output: Generally considered to be between 800 ml and 2000 ml per day.
Therefore, a urine output falling below the 300 ml threshold indicates oliguria.
