What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a new monitoring device can predict acute kidney injury (AKI) in adults undergoing heart surgery or procedures using contrast dye. The device measures kidney function in real time through the skin after a fluorescent tracer is injected. Researchers will track these measurements to see if they can warn of AKI earlier than standard blood tests. The goal is to improve early detection and potentially prevent serious kidney damage.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcutaneous fluorescence glomerular filtration rate (GFR) monitoring
What this could lead to
If successful, this could lead to a real-time early warning system that flags kidney injury hours before current tests, allowing faster treatment and potentially preventing severe kidney damage.
What could go wrong
This is an observational study, so it won't test a treatment. The monitoring method may not prove accurate enough in practice, and results may not apply to all patients or hospital settings.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients undergoing cardiovascular surgery or receiving iodinated contrast media who are at risk of acute kidney injury (AKI), as well as patients diagnosed with cardiac surgery-associated acute kidney injury (CSA-AKI) or contrast-associated acute kidney injury (CA-AKI), will be prospectively enrolled. Participants will undergo perioperative or peri-procedural transcutaneous glomerular filtration rate (GFR) monitoring to evaluate GFR trajectories for the early prediction and diagnosis of AKI.

Ages

18 years and older

Sex

Anyone

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age ≥ 18 years old; 2. Specific inclusion criteria for the cohort: * GFR trajectory characterization after cardiovascular surgery or Iodine contrast agent exposure: Patients scheduled for elective cardiovascular surgery or interventional cardiovascular surgery or CTA; ② GFR trajectory characterization of AKI: Patients with confirmed CSA-AKI or contrast-associated acute kidney injury (CA-AKI). Exclusion Criteria: 1. Received renal replacement therapy before surgery or before contrast imaging, including kidney transplantation and regular dialysis; 2. Serum creatinine \> 353 μmol/L before surgery or before contrast imaging; 3. Patients with AKI who did not recover before surgery or before contrast imaging; 4. Patients with malignant tumors.
