Objective: To determine correlation between PCR calculated by, kinetic model of urea and the protein ingestion determined by dietetic survey. Material and Methods: Study of correlation analysis. We included 15 children with chronic renal failure (CRF). We calculated PCR by dietetic survey of consumption frequency at last 24h for 3 days and by kinetic model of urea at beginning and finalize of the study. Results: 46.67%(7) were males and 53.33%(8) females. The mean age was 15 ±2 years old. The initial mean PCR measured by urea kinetic model was 0.993±0.27 and 0.996 ± 0.28 by dietetic survey and its correlation was r = 0.9962 and R² = 0.9924. At the end of the study was 1.07± 0.28 and 1.06± 0.27 by dietetic survey and urea kinetic model respectively and its correlation was r = 0.9973 and R² = 0.9924. Serum albumin was normal in 20% of patients at the beginning of study and 86.67% one year after. Conclusion: Good correlation between the PCR calculated by the kinetic model of urea generation and the protein ingestion determined by the dietetic survey exists (Rev Med Hered 2006;17:77-80).
