Feasibility of Triggered Sacral Neuromodulation for Neurogenic Bladder

About this trial

This trial is enrolling individuals with chronic spinal cord injuries and bladder dysfunction, to test the feasibility of a technique that electrically stimulates nerves in the lower spinal cord (sacral nerves). Researchers want to see if this stimulation affects bladder function (bladder capacity, filling pressure, and contractions). If included, participants will have a small wireless sensor (UroMonitor) temporarily inserted into their bladder to measure bladder pressure and this pressure data will be transmitted to an external radio. A skin-surface electrical stimulator will then automatically turn on sacral nerve stimulation based on the pressure information from the UroMonitor. The stimulation will either be applied for: 1) up to eight hours at three timepoints over a two-week period; or 2) in a continuous fashion for two weeks. Final testing will be performed after 2 weeks.
