What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

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 Results may not be published yet.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.

Summary

This study tests whether a device called FIZE kUO®, which tracks urine output every minute, can help doctors manage fluids and diuretics in patients recovering from heart surgery. Researchers will monitor 45 adults in the intensive care unit and compare urine output before and after treatments. The goal is to see if real-time data can guide care and possibly lower the risk of kidney injury.

What this could mean

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

Active substance
FIZE kUO®, a non-invasive device that continuously measures urine output in real time in patients with a urinary catheter
What this could lead to
If real-time urine output monitoring helps doctors tailor fluids and diuretics after cardiac surgery, it could reduce kidney injury and improve recovery.
What could go wrong
This is a small observational study, so it cannot prove cause and effect. The device may not change outcomes, and results may not apply to all surgery patients.
