No-Catheter bladder test shows promise in small study
NCT ID NCT05959655
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new wireless device called the Glean Urodynamics System (GUS) that measures bladder pressure without a catheter. Thirty-eight adults with urinary symptoms used the device after a standard test. The goal was to see if the device is safe, easy to use, and more comfortable than the traditional method.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Glean Urodynamics System (GUS) - a wireless, catheter-free device
- What this could lead to
- If successful, this device could offer a more comfortable way to diagnose bladder problems, replacing the standard catheter-based test.
- What could go wrong
- This was a small, early feasibility study with only 38 participants, so results may not apply to everyone. The device may not work as well as the standard test.
