The purpose of the study is to learn if monitoring dialysis access blood flow during dialysis
treatment with a transonic machine (an ultrasound technique) will prevent (or reduce) the
development of dialysis access thrombosis (clotting).

Investigators would like to study if monitoring with a specific technique called ultrasound
dilution technique can help prevent problems with access when compared to what is the current
standard of care for patients.

Inclusion Criteria:

- Chronic hemodialysis patients undergoing dialysis therapy via an upper extremity
arteriovenous access (arteriovenous fistula or an arteriovenous graft) will be
enrolled to have monthly surveillance flow measurement using Transonic system or
physical examination of the arteriovenous access by qualified person at least once a
month for a period of 2 years.

Exclusion Criteria:

- Patients requiring surgical intervention on the arteriovenous access.

- History of access thrombosis (one or more access thrombosis of the current
arteriovenous access).

- Patients with signs of access infection.

- Patients with a malignancy.

- Patients with life expectancy of less than six months.

- Unable to understand the study.

- Unable to sign the consent form.

- Patients with psychiatric disorder.

- Age less than 18 or greater than 80 years.

- Adults unable to consent

- Individuals who are not yet adults (infants, children, teenagers)
