Botox shot may help stop leaky bladder – early study hopes
NCT ID NCT04984317
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests whether a one-time injection of Botox into the bladder muscle can reduce urine leakage in women with stress urinary incontinence. Twenty women who have not improved with other treatments will receive the injection and be monitored for changes in leakage and side effects. The trial is currently suspended, and results are not yet available.
