Could air make bladder exams clearer during active bleeding?
NCT ID NCT07618221
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using air instead of saline to inflate the bladder during a flexible cystoscopy helps doctors find the source of bleeding in people with visible blood in their urine. Participants are randomly assigned to receive either an air-based or saline-based exam. The main goal is to see if air improves the ability to identify the bleeding source, with secondary measures including how quickly the source is found and patient comfort.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If air-based cystoscopy proves better, it could become a standard technique for diagnosing the cause of visible blood in urine, especially during active bleeding.
- What could go wrong
- This is a small, early-stage study with only 40 participants, so results may not apply broadly. Air insufflation carries a small risk of air embolism or bladder injury.
