Purpose of the study: The conditions of renal replacement therapy (RRT) were very poor in the countries located in Central and Eastern Europe (CEE) when they were members of the so-called 'socialist bloc'. The aim of the present analysis was to document the impact of the socioeconomic changes on dialysis therapy in the CEE countries.
Design: This was a special survey with the participation of 12 CEE countries, with data obtained through national registries (with the exception of Russia).
Results: During the period 1990-1996 the number of haemodialysis units increased by 56% and the number of centres performing peritoneal dialysis by 296%. The number of patients increased respectively by 78% (haemodialysis) and 306% (peritoneal dialysis). The percentage of patients with diabetic nephropathy and elderly patients rose dramatically during this period. One of the main reasons of such expansion was the rapid development of peritoneal dialysis programmes in the majority of the CEE countries. The introduction of modern haemodialysis machines and a wider choice of different dialysers and concentrates permitted individualization of dialysis procedures. These points and the wider use of erythropoietin had a positive influence on quality of life and treatment outcome. There was also a notable increase in the number of transplant centres, but less so of the number of transplanted patients.
Conclusion: Renal replacement therapy experienced a major expansion in the CEE countries. Despite the progress achieved, the level of RRT is not yet completely satisfactory in most CEE countries.
