Plain-English translation of NCT05612022 on ClinicalTrials.gov ↗ ·
Doctors have long listened to dialysis access points with a stethoscope to check if they're working well, but this has never been formally studied. This trial is testing whether recording and analyzing these sounds—paired with standard ultrasound imaging—can reliably detect problems like reduced blood flow or narrowing before the access fails completely. If successful, this simple acoustic method could help prevent access failure and keep patients on dialysis longer.
Dialysis access points (both surgically created fistulas and grafts) often fail or develop problems that go undetected until it's too late, forcing patients to have emergency surgery or switch to less ideal dialysis methods. There is currently no good surveillance strategy to catch these problems early. This study aims to develop a simple, non-invasive tool to monitor access health over time.

You will have sound recordings made of your dialysis access using a small microphone, along with standard ultrasound imaging to check blood flow. These recordings and ultrasounds will be done at certain time points as part of your regular follow-up care. The study is observational, meaning you won't receive any new medication or invasive procedure—researchers will simply monitor your access using these non-invasive techniques and track whether the acoustic method helps predict problems.
