Purpose: Excess extracellular volume is a major clinical problem in patients with chronic kidney disease and it can cause mortality. However, the detection of disrupted volume distribution in children with chronic kidney disease is difficult. In this study, we aimed to assessment of body hydration status of chronic kidney disease with bioelectrical impedance analysis. Materials and methods:The study included a total of 52 patients (peritoneal dialysis=16, hemodialysis=12, chronic kidney disease stages 3-4= 24) and 46 healthy children. Each child’s body fluid compositions was measured by bioelectrical impedance analyzer (BIA 101) (50 kHz fixed frequency with the conventional tetrapolar technique). Intracellular fluid, extracellular fluid, and total body water were calculated from obtained values. The Kruskal Wallis, independent sample t-way variance analysis and t-test were used for statistical analysis. Results: When the children were evaluated for excess liquid and dispersion, extracellular fluid and total body water were not different between patient and control groups. However, cardiothoracic ratio measurements in peritoneal dialysis and hemodialysis patients were detected significantly higher than pre-dialysis control groups. Conclusion: Since healthy subjects’ hydration level is referred for the calculation of bioelectrical impedance analysis, the results of impaired fluid distribution in children with chronic kidney disease was thought to be controversial.
