Scientists hunt for clues in gut and urine to understand urinary blockages
NCT ID NCT07409870
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study will compare the gut and urine bacteria, as well as metabolic profiles, of 120 people with ureteral stricture (a narrowing of the tube from kidney to bladder) against healthy volunteers. Researchers aim to find differences that could explain why the condition develops and identify potential markers for diagnosis. Participants provide stool, urine, and blood samples and undergo standard imaging and lab tests.
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 successful, this could identify new biomarkers for diagnosing or monitoring ureteral stricture, and point toward future microbiome-based treatments.
What could go wrong
This is an early observational study, not a treatment trial. It may not find clear differences, and any discoveries would need years of further research to become useful.
