Introduction
Patients with End-stage renal disease (ESRD) undergoing
maintenance hemodialysis (HD) have a high risk of morbidity
and mortality [1]. Therefore, the most effective and best-tolerated
HD treatment may improve clinical outcomes in this patient
population [2]. In particular, the dialyzer used in HD treatment is
one of the important determinants of the effectiveness of dialysis.
HD using high-flux dialysis membrane can clear more middle
molecular weight uremic toxins such as b2-microglobulin than
HD using low-flux dialysis membrane because of its higher
porosity [3].
