Through a multi-center, prospective cohort study, hemodialysis patients with right internal jugular vein catheterization were collected and divided into tunnel-cuffed catheter group and non-cuffed catheter group according to the types of catheterization. The incidence of catheter infection, thrombosis and other complications between the two groups were compared.To clarify the difference of short-term infection rate between tunnel-cuffed catheter and non-cuffed catheter.

Inclusion Criteria:

• ① Age ≥18 years; ② Uremia, clinical evaluation needs to start hemodialysis immediately, and the right internal jugular vein catheterization is the vascular access for the subjects. ③ Subjects who underwent right internal jugular vein catheterization on regular hemodialysis due to poor internal fistula function and the recovery time of internal fistula was ≥4 weeks; ④ Patients with AKI who need renal replacement therapy and underwent catheterization in the right internal jugular vein, and the renal replacement time is ≥4 weeks.

Exclusion Criteria:

• ① Subjects with previous history of central venous thrombosis, stenosis, infection, etc. ② The subjects were not dialyzed three times a week; ③ Other subjects with central venous catheterization, including left internal jugular vein, femoral vein and subclavian vein; ④ Those who take immunosuppression for a long time.
