Oliguria: Causes and Effects of Decreased Urine Output

10. Treatment

Treatment of oliguria and kidney failure depends on the cause. If dehydration is the culprit, IV fluids can rehydrate the patient. If fluid has begun to build up in the tissue, the doctor may prescribe diuretics to help the kidneys eliminate the fluid buildup. Medications can also correct electrolyte imbalances, particularly blood potassium levels. If kidney failure and the associated oliguria persist, the patient may require dialysis to restore his or her electrolyte balance.
