Treatment is dependent on the underlying cause of this symptom. The most easily treatable cause is obstruction of urine flow, which is often solved by insertion of a urinary catheter into the urinary bladder. Mannitol is a medicine that is used to increase the amount of water removed from the blood and thus improve the blood flow to the kidneys. However, mannitol is contraindicated in<unk>  secondary to renal disease, severe dehydration, intracranial bleeding (except during craniotomy), severe pulmonary congestion, or pulmonary edema. Dextrose and dobutamine are both used to increase blood flow to the kidney and act within 30 to 60 minutes.
