[Developing trends in the active therapy of kidney failure. Hemodialysis--hemofiltration--hemoperfusion].

A survey is given on the modern level and the developmental trend in the apparative therapy of renal insufficiency. Apart from the description of the actual medical, technical and organisational problems in the haemodialysis the methods of the haemofiltration and the haemoperfusion are investigated with regard to the modern experimental and clinical state of knowledge as well as to the theoretical possibilities of their clinical use alone or in combination together.
