Effect of Different Blood Purification Methods on Residual Renal Function in Maintenance Hemodialysis Patients

Objective: This study aims to evaluate the efficacy of different blood purification methods in protecting residual renal function (RRF) in patients with maintenance hemodialysis (MHD). Methods: The study selected 50 patients receiving MHD between September 2023 and September 2024. Using the random number table method, patients were divided into the control group and the study group, each with 25 participants. The control group received hemodiafiltration, while the study group was treated with hemodialysis plus hemoperfusion. The RRF measures of the two groups were compared. Results: There were significant differences in the RRF measures (P < 0.05). Conclusion: Combined hemodialysis and hemoperfusion therapy can effectively improve the RRF index of MHD patients with a significant curative effect.
