The goal of this trial is to investigate the prognostic value of monitoring finger blood pressures (FBPs) in predicting the success of surgically created arteriovenous fistula (AVF) for patients with end stage renal disease. The main questions it aims to answer is:

- Can FBPs predict AVF maturation?

Participants will undergo FBP measurements at pre-op, immediately post-op, 4 weeks and 6 weeks post-AVF creation.

Inclusion Criteria:

• Participants has documented Chronic Kidney Disease (CKD), determined by Glomerular Filtration Rate (GFR)
• Participant is recommended for renal replacement therapy based on clinical assessment of renal function as well as CKD staging, as documented in clinical notes.
• Haemodialysis was chosen as the most appropriate renal replacement therapy
• Participant is able to consent to the creation of an AVF in preparation for hemodialysis.
• Participant is able to adhere to follow-up assessments of AVF maturation, if applicable.

Exclusion Criteria:

• Subject had a previous AVF and is now undergoing surgery for another AVF creation
• Subject has amputation distal to AVF
• Subject is pregnant or planning to conceive
• Participants is unable to consent
