Urine output, decreased

Alternative names:

oliguria

Definition:

A reduced ability to make and excrete urine, usually less than 1 pint a day.

Considerations:

Very often a significant decrease in urine output indicates a serious, and perhaps even a life-threatening, problem. With proper and prompt treatment, this condition can often be corrected.

Common causes:

• lack of water intake
• drugs such as adrenergic agents, anticholinergic agents, aminoglycoside antibiotics, cisplatin, digitalis toxicity, diuretics (water pills), methotrexate, and sulfonamides
• radiographic studies that use contrast media
• acute post-streptococcal GN
• hemolytic uremic syndrome

Note: There may be other causes of oliguria. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as time course, aggravating factors, relieving factors, and associated complaints.
