Official Title: Cohort Study on A Following-up System of Native Arteriovenous Fistulae in Chinese Patients Treated by Maintenance Hemodialysis

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.

Detailed Summary:

The Following-up System of AVF includes 3 stages. In the 1st stage, before AVF surgery operation, the contents of Following-up System of AVF include history, physical exam, ultrasonography detection. The assesment results will guide the methods of the AVF surgery operation. In the 2nd stage, before AVF puncture firstly and 3 months after AVF operation, the contents of Following-up System of AVF include physical exam and ultrasonography detection. The results will help the nurses and doctors make a decision of the method of AVF puncture. In the 3rd stage, during the following 2 years after AVF puncture successfully, the contents include physical exam and ultrasonography detection regularly. The adequacy of hemodialysis by using AVF will be assessed by urea clearance index (Kt/V).

The data of patients in other hemodialysis centers will be recorded and compared to the patients in experiment group.

Current Primary Outcome: Primary Failure of AVF [ Time Frame: 3 months after surgery ]

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.


Original Primary Outcome: Same as current

Current Secondary Outcome: Life time of AVF [ Time Frame: 2 years ]

The life time of an available AVF since the AVF is functionable. The life time of an AVF is a period time from the AVF used for hemodialysis treatment at first time to the last time when the AVF can not be used for hemodialysis therapy. Since the AVF will be punctured in every hemodialysis session, the function of AVF were detected during every treatment session (3 times per week).


Original Secondary Outcome: Life time of AVF [ Time Frame: 2 years ]

The life time of an available AVF since the AVF is functionable. The life time of an AVF is a period time from the AVF used for hemodialysis treatment at first time to the last time when the AVF can not be used for hemodialysis therapy.
