Super high-flux HD is quite popular in Japan. 90% of -dialysis patients are treated using dialyzers with a β<sub>2</sub>-microglobulin clearance of >50 ml/min. If the target is β<sub>2</sub>-microglobulin, HDF is not necessary. However, removal of uremic toxins with a higher molecular weight and stability of circulation status, which is expected of on-line HDF, would lead to better survival of the patients. Demonstration of the beneficial effect of on-line HDF on the outcome in patients is awaited.
