The effect of renal transplantation on pulmonary function and respiratory muscle strength in patients with end-stage renal disease.

Pulmonary function and respiratory muscle strength was assessed in 29 hemodialysis patients who underwent successful renal transplantation. These tests were performed 7 days prior to transplantation, 30 days following transplantation, and 90 days posttransplantation. Patients with end-stage renal disease showed dyspnea, a restrictive defect in pulmonary function, respiratory muscle weakness, and hypoxia. Following transplantation the dyspnea improved and mechanical indices of respiratory muscle function and lung volume improved. In conclusion transplantation resulted in a significant improvement in lung and respiratory muscle function.
