Wireless bladder sensor could help veterans regain control
NCT ID NCT05141487
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new type of nerve stimulation to help Veterans with bladder control problems caused by nerve damage. A small wireless sensor is placed in the bladder to detect when it is filling and trigger stimulation to prevent leakage. The goal is to see if this approach works better than standard continuous stimulation.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study will enroll 16 patients undergoing treatment at the VANEOHS (US Veterans). Participants will have a diagnosis of neurogenic bladder with a recent (within one year) multi-channel UDS evaluation. Participants will be selected as those with neurogenic bladder symptoms most likely to respond to SNM treatment based on evidence-based recommendations (i.e reasonable bladder capacity, non-catheter dependent, ability to identify and manage bladder needs - as based upon assessment by clinical experts / co-investigators). Participants will be screened to meet inclusion/exclusion criteria. Implantation of bilateral percutaneous stimulating electrodes, setting of SNM stimulation waveforms, and the use of an external continuous SNM stimulator will follow clinical standard of care for prospective evaluation for Medtronic Interstim treatment.
