Hidden bacteria in your bladder may hold key to better UTI diagnosis
NCT ID NCT07020676
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at the bacteria living in the bladder (urinary microbiota) of 108 women, some with urinary tract infections (UTIs) and some healthy. Researchers used advanced DNA sequencing to find bacteria that standard lab tests miss. The goal was to understand how changes in these bacteria might cause UTIs and to improve how we detect them.
