Background and Aim: In children with end-stage kidney disease, one of the renal replacement methods including hemodialysis, peritoneal dialysis and kidney transplantation are selected for survival. In the dialysis process, the serum ca, Pi, and PTH levels are variable. Ca-ph levels increase in these patients, resulting in calcification, and calcium absorption of the gastrointestinal tract in CKD patients decreases. Chronic acidosis also reduces bone density by increasing calcium intake from the bone. KDOQi (2003) recommends that the ca-ph product be kept below 55 mg / dL. In this study, according to the standard National Kidney Foundation (KDOQi) a comparison of the adequacy of life of hemodialysis patients and peritoneal dialysis based on the changes in blood Ca-Ph and PTH was investigated.Method: This was a retrospective cohort study of children under 18 years who were under treatment in Ali-Asghar children hospital between 2014 and 2017. During this period, the level of Serum calcium, phosphorus, and parathyroid hormone were measured. Data presented as mean (SD) and the percentage of patients who met the K/DOQI guideline.Result: Eight patients were under hemodialysis and 56 were on CAPD during past three years. The detail of calcium (ca), phosphorous (Pi), PTH were shown in Table. Although mean calcium was similar in two groups but CAPD patients had higher Pi and PTH level.Conclusion: This study shows that hemodialysis method is more effective in controlling the level of PTH in KDOQi PTH guidelines than peritoneal dialysis
