[Urea kinetics model of patients on programmed hemodialysis].

Fifty three patients with programmed hemodialysis, in a stable state were studied to the method of urea-kinetic modelling. A high correlation relationship was established between the pre-dialysis values of urea nitrogen in blood and the protein import, calculated from the quantity of the endogenously produced urea nitrogen. The best rehabilitated patients (41,5%) proved to introduce 1,0-1,6 g/kg body weight proteins and maintain a concentration of blood urea nitrogen from 65-95 ng% (32,14-33,8 mmol/1).
