Urine output - decreased

• Overview
• Treatment

Definition:

Decreased urine output is defined as producing less than 500 milliliters of urine in 24 hours.

Alternative Names:

Oliguria

Considerations:

Although a significant decrease in urine output may indicate a serious, even life-threatening condition, adequate urine output can be restored with prompt medical treatment.

Common Causes:

• Dehydration due to vomiting, diarrhea, or fever, with a lack of adequate fluid intake
• Total urinary tract obstruction, such as may result from an enlarged prostate
• Severe infection leading to shock
• Drugs such as anticholinergics, methotrexate, and diuretics
