Pulmonary hypertension is a new complication described in hemodialysis patients. in the last year these patients were treated by calcium carbonate orally to control serum phosphor. Calcium phosphor deposits in pulmonary artery can explain this phenomena. The investigators want to investigate the new phosphor non calcium containing agents in hemodialysis patients and to measure the pulmonary pressure.

The investigators will measure pulmonary blood pressure before and after treatment with new phosphor binders, non calcium containing.

Inclusion Criteria:

• Hemodialysis Patients without fistula

Exclusion Criteria:

• Heart Disease

40 patients on hemodialysis treated with Phosphore biders, non-calcium containig.
