What work best to treat pulmonary edema if the person has renal failure?

Pulmonary Edema tx: Patients with renal failure on dialysis need to be ultrafiltrated (uf). Here the patient is placed on dialysis and extra fluid is removed from the body through the artificial kidney. As dialysis patients make little urine, diuretics are of no use. Uf can remove 3 liters of fluid in 2 hours improving the patients symptoms of dyspnea. The real question is, why is the patient in pulmonary edema?

Pulmonary edema: Get the water out of the lungs either using diuretics if there is enough renal function left to allow this to happen or remove the water acutely using hemofiltration. If this is due to renal and heart failure, the heart failure also has to be managed aggressively.
