NCT02880761

Brief Summary

A cohort including more than 100 maintenance hemodialysis patients will be followed up according to a certain Following-up System of Native Arteriovenous Fistulae (AVF) prospectively. The assessment results of the Following-up System of AVF help the physicians make decisions of AVF surgery and puncture methods. The results of this study would identify the effect of the system on survival of AVF. Other 100 hemodialysis patients from other centers will be treated by routine protocol and compared to the experiment goup.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Fistula Failure

    The AVF can not be used for hemodialysis treatment 3 months after surgery, which it is defined as Primary Failure of AVF. The primary failure of AVF is regarded as the primary outcome of the patients who were followed up. The ratio of primary failure will be compared between two groups.

    3 months after surgery

Secondary Outcomes (1)

  • Life Time of AVF

    Equal to or larger than 2 years

Other Outcomes (1)

  • Mean Value of Urea Clearance Index During 24 Months

    2 years

Study Arms (2)

Intervention

EXPERIMENTAL

Patients with AVF will be followed up by a preset following-up system. Interventions would be administered according to the assessment for AVF, which including the surgery and puncture of AVF. For AVF surgery, a certain vein would be used in the operation according to the assessment results. For AVF puncture, the methods, such as 'button hole', 'rope ladder', dwelling needle, would be selected prospectively according to the assessment results.

Procedure: Assessment guiding surgery and puncture for AVF

Control

NO INTERVENTION

Patients in other hemodialysis centers who are treated by routine protocal would be enrolled into control group. Their clinical data would be collected and compared with intervention group.

Interventions

Assessment guiding surgery and puncture for AVF. Assessing the parameters of vascular vessels during following-up and making suggestions on surgery and puncture of AVF
