Recruitment & Eligibility

• Status: Completed
• Sex: All
• Target Recruitment: 144

Inclusion Criteria

Both groups will be recruited in the same way through the renal consultants and will be randomly allocated to one of two groups. It is predicted that the sample size will be no more than 144 patients in the first year as this is the predicted maximum number of patients requiring primary AVF in this timescale. It is predicted that the final number of patients required for the sample will be approximately 50 per group as a result of a retrospective study performed previously by Robbin et al (2002).

1. Adult patient requiring primary AVF
2. No previous AVF or dialysis via central line
3. Upper limb vein/artery suitable for AVF formation
4. The patients' eGFRml/min/1.73m^2 must be greater than 15 to minimise likelihood of access being required before maturation of primary AVF

Exclusion Criteria

1. Children (<18 years old)
2. Those patients unable to give consent
3. AVG formation required
4. Previous AVF
5. Previous access via central line
6. Patients with failing transplant
7. Patients undergoing peritoneal dialysis
