Pill or needle? new study tests two treatments for bladder leaks
NCT ID NCT05806164
First seen Jun 27, 2026 · Last updated Jun 30, 2026 · Updated 2 times
Summary
This study compares two treatments for women with urgency urinary incontinence (sudden, strong urges to urinate that lead to leakage). Participants will be randomly assigned to take an oral beta-agonist pill or receive Botox injections into the bladder. The main goals are to see which treatment women are more satisfied with and which better reduces their symptoms, with follow-up lasting up to 5 years.
