Answer

Patients with oliguric ATN have a worse prognosis than patients with nonoliguric ATN. This probably is related to more severe necrosis and more significant disturbances in electrolyte balance. In addition, a rapid increase in serum creatinine (ie, >3 mg/dL) probably also indicates a poorer prognosis. Again, this probably reflects a more serious underlying disease.
