[Basic disturbances and extra-renal complications - prognosis determining factors in acute renal failure].

The author adopts a definite attitude to the prognosis of acute renal failure, based on the experiences of 410 peritoneal dialyses and 168 haemodialyses in 165 patients. In a total lethality of 51% there is no relation between the choice of the technique of dialysis and lethality. The changes of survival are mainly determined by the causal disease and its extrarenal complications. The worst prognosis have patients with a breakdown of other vital functions besides renal failure. The possibility of the alternative treatment haemodialysis/peritoneal dialysis should always be given.
