Friendly bacteria bladder wash aims to stop UTIs without antibiotics
NCT ID NCT04846803
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether washing the bladder with a harmless strain of E. coli can prevent recurrent urinary tract infections (UTIs) in people who have failed other treatments. Researchers will compare the harmless bacteria wash to a saltwater wash in 80 participants, tracking how many UTIs occur over time. If successful, this could offer an antibiotic-free prevention option.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
non-pathogenic E. coli bacteria (ABU strain) for bladder lavage
What this could lead to
If it works, this could offer a new way to prevent recurrent UTIs without antibiotics, reducing the need for frequent medication.
What could go wrong
This is a small, early-stage trial (80 people) testing a novel approach. The bacteria may not outcompete harmful strains in all patients, and long-term effectiveness is unknown.
