【摘要】目的 探讨维持性血液透析不同透析方式的疗效。方法19例患者分为两组，6例患者行血液透析滤过加血液透析(HDF/HD),13例患者单纯行血液透析(HD)，两组患者均持续透析5个月。透析前后分别采血测尿素氮及肌酐并计算KT/V及PCR值。结果 HDF/HD清除尿毒素和透析充分性明显优于HD， 两组PCR无显著性差异(P>0.05)。结论 血液透析滤过联合血液透析是维持性血液透析患者可供选择的一种较好透析方式。

【Abstracts】Objectives To investigate the efficacy of different dialysis modalities in maintenance hemodialysis patients. Methods 19 patients were given two groups randomly.13 patients undergone hemodiafiltration and hemodialysis，the other 6 patients were treated with hemodialysis for only 5 months.The predialysis and postdialysis serum urea nitrogen and creatinine were measured.The values of KT/V and PCR were calculated. Results HD combined HDF is better than HD in clearance of urotoxin and dialysis adequacy. There is no significant difference in PCR between the two groups Conclusions Hemodiafiltration assoiciated with hemodialysis is considered to be the better treatment of choice for maintenance hemodialysis patients.
