We performed this study in order to find the frequency and severity of renal osteodystrophy (ROD) in our patients with chronic renal failure who were either on hemodialysis or continuous ambulatory peritoneal dialysis (CAPD) programs. We compared these two groups of patients in respect of ROD and divalent ion metabolism, to see whether there was any difference which might be due to different dialysis methods. 30 patients who were being followed by Ege University Dialysis unit were admitted to this study. 15 of the patients were receiving hemodialysis while the other half were on CAPD treatment. Divalent ion metabolism, and immunoreactive parathormone (iPT/1) levels were investigated in both groups. In addition, X-ray lesion, bone scans, and bone histology Were studied. In both hemodialysis and CAPD groups, mild ROD detected, but severity and bone frequency of ROD was not statistically different in either group.
