Definition of Urine output - decreased:

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

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 from an enlarged prostate
Severe infection or any other medical condition leading to shock
Use of certain medications such as anticholinergics, methotrexate, and diuretics
