Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Haemodiafiltration post-dilution model
Treatment: Surgery - Haemodialysis

Active comparator: Haemodialysis - regular convectional haemodialysis 3times/weekly

Active comparator: Haemodiafiltration - post-dilution haemodiafiltration


Treatment: Surgery: Haemodiafiltration post-dilution model
Participants will be randomly assigned into either HD or HDF group. The participants will received the assigned treatment for 2 months, 1 month wash-out (HD) and cross-over to the other dialysis model- eg. HDF (2months) and switch to HD for 2 months, with 1 month washout period (using standard HD). Haemodialysis post-dilution model will be delivered using fresenius 5008 machine. Prescription for HDF post-dilution will be comparable to HD.
