Urine output - decreased

Definition:
This symptom is described as decreased urine output, defined as less than 500 ml in 24 hours.

Alternative Names:
Oliguria

Considerations:
Though a significant decrease in urine output may indicate a serious, and even life-threatening condition, adequate urine output can often be corrected with prompt medical treatment.

Common Causes:
  • Dehydration due to vomiting, diarrhea or fever, and concomitant lack of adequate fluid intake
  • Total urinary tract obstruction, such as resulting from an enlarged prostate
  • Severe infection leading to shock
  • Drugs such as anticholinergics, methotrexate, and diuretics
