Choice of modality with the use of high-performance membrane and evaluation for clinical effects

The golden target for dialysis therapy should be to guarantee longer survival and to give a higher quality of life without dialysis-related complications. In order to achieve this target, the choice of dialysis modality and membrane is essential but we have not yet established what the best choice for a dialysis modality and membrane are. Generally, we choose a dialysis modality for better solute removal and better biocompatibility. In this issue we would like to propose that the patients' preference for dialysis therapy is a useful parameter in prescribing the dialysis modality. In our recent experience, chronic dialysis patients have had preferences on a dialysis modality and membrane, those being PMMA, EVAL, AN-69 and pre-dilution online HDF. These modalities could relieve them of uncomfortable dialysis-related symptoms such as insomnia, itchiness, irritability, and so on. Other characteristics of these modalities are of a nutritional advantage, a broad removal pattern of uremic toxins including low-molecular-weight protein and protein-bound uremic toxins, and good biocompatibility free from chemical components of dialysis membrane. In conclusion, patients' symptoms could be a useful parameter to choose a dialysis modality and membrane.
