Haemodialysis is a basic extracorporeal elimination treatment and peritoneal dialysis is a basic intracorporeal treatment in chronic kidney failure (CKF). In recent years there has occurred a progress in physiology and pathophysiology of the kidneys and at the same time also technical progress at application of elimination methods of CKF treatment. Nowadays thank to these facts there are available various modifications of the above mentioned treating elimination methods. Haemodialysis has following modifications: haemofiltration, haemodiafiltration and continuous extracorporeal elimination methods (continuous arteriovenous and venovenous haemofiltration, continuous arteriovenous and venovenous haemodialysis, continuous arteriovenous and venovenous haemodiafiltration, and continuous arteriovenous and venovenous „high flux“ dialysis). Peritoneal dialysis with use of biocompatible dialysis solution, e.g. with icodextrin, has following modifications: continuous ambulatory peritoneal dialysis, continuous cyclical peritoneal dialysis and automated peritoneal dialysis by use of the equipment - „cycler“, night intermittent peritoneal dialysis and tidal peritoneal dialysis. All mentioned methods have their advantages and disadvantages and their use has to be individualised according to actual need in patients with CKF. At present haemodiafiltration and continuous ambulatory peritoneal dialysis is used the most frequently, which prepares a patient for successful kidney transplantation.
