What is the normal urine output expected per hour for a patient with a Foley catheter?

The normal urine output for a patient with a Foley catheter is approximately 30 mL per hour. This amount is considered an indicator of adequate renal function and hydration status. Monitoring urine output is essential in clinical settings, especially for patients who may be at risk of fluid imbalances.

Urine output below this threshold, such as 15 mL per hour, may signal issues like dehydration, renal impairment, or obstruction, while significantly higher outputs, like 45 mL or 60 mL per hour, could suggest conditions like diuresis or excessive fluid intake. Maintaining an output around 30 mL per hour shows that the kidneys are functioning properly, indicating that they are efficiently filtering and excreting waste products.
