Abstract: Objective To investigate a reasonable way for reducing HCV infection in hemodialysis patients dialyzed with reused dialyzer. Methods Dialyzers were reused with Renalin 100 as disinfectant and Renatro PA 100 The dialyzers of HCV Igm positive patients were for single use.Dialyzers of anti HW IgG positive patients were reused and stored seperately with those of anti-HW IgG negative patients. All patients were examined HCV IgG and HCV IgM at an interval of 6 months in 3 years. Results The results of HCVIgG were similar in both groups（P＞0.05）. The number of HCVIgM positive patient was 0 in all patients. The incidence of positive anti-HCV IgG was similar between all retreating patients and all examined patients(P＞0.05). Conclusion Using Renalin100 to disinfect the reused dialyzer and Renatro PA 100 to reuse the dialyzers, using the dialyzers of anti-HCV IgM positive patients once, reusing the dialyzers of anti-HCVIgG positive patients seperately with those of anti-HCVIgG negative patients, could prevent HCV infection. The way is safe and effective.
