Implant zaps bladder nerves to stop sudden leaks
NCT ID NCT03327948
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a device that uses mild electrical pulses to calm the nerves controlling the bladder. It was for people with sudden, strong urges to urinate that cause leaks, who didn't get help from other treatments. The goal was to see if the device safely reduces leaks by at least half.
