The experience of the introduction of convective methods since the eighties of the 20th century is described. Aim: to evaluate the influence of convective transport supplementation on renal replacement therapy results. Methods and results. The number of convective procedures was applied: hemodiafiltration with commercial substituted fluid, paired filtration dialysis, acetate-free biofiltration, original hybrid methods, online hemodiafiltration. The main trend was the magnification of substituted volume. In the long run after switching from conventional dialysis to convective therapy the increase of Kt/V, the decline of phosphate, the rise of serum albumin, the decrease of CRP level and ESA consumption, QOL improvement and the drop in severity of intradialysis complications were observed. Over last six years online hemodiafiltration has become the standard of dialysis therapy in our Center. Conclusion. The undoubted advantages of convective modalities and accessibility of online hemodiafi ltration make these methods the gold standard of dialysis therapy.
