title: [Urea kinetics model of patients on programmed hemodialysis].
abstract: 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). Furthermore, another three patient groups were formed: with reduced protein introduction, with insufficient clearance and with overnormal protein introduction. The optimal group significantly differ from them, according to the state of nourishment, general rehabilitation, phosphatemia, calcium-phosphorus number and dialysis clearance. Both the stage of anemia and arterial hypertension show only a tendency in similar direction.
