Measure
Urodynamic Testing and LLP With and Without Pudendal Nerve Stimulation
Commercially available stimulation needles or leads will be inserted into the peri-urethral space targeting the perineal branch of the pudendal nerve. An external neurostimulator settings will be adjusted to deliver acute stimulation. Urodynamic testing will be completed by filling the bladder to a set volume and observing for urinary leakage. The assessment will be completed with stimulation turned on and off. The neurostimulator device settings will be adjusted by the investigator to stay within safe and comfortable levels for each individual study participant.

PRIMARY outcome

Timeframe: At stimulation visit, 1 day

Population: No data was collected. No pressure response was observed in any of the patients; thus pressure measurement data was not obtained and recorded for analysis. No data will be collected in the future. This was not an effective method to collect this information.

Measurement of the change in intra-urethral pressure with peri-urethral neurostimulation compared to intra-urethral pressure with no stimulation.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: One week after completing the stimulation visit

Population: Participants that reported adverse events

Safety and tolerability of peri-urethral stimulation will be assessed in related to the incidence of adverse events reported within one week of stimulation visit.

The neurostimulator device settings will be adjusted by the investigator to stay within safe and comfortable levels for each individual study participant. Urodynamic testing with and without pudendal nerve stimulation: A urodynamic test with and without neurostimulation will be conducted. The external neurostimulator device settings will be adjusted to deliver acute nerve stimulation per the individual tolerance level to assess the effect on urethral pressure. A leak point pressure (LLP) during Valsalva maneuver will be assessed with and without acute nerve stimulation.
Safety and Tolerability Will be Assessed in Relation to the Incidence of Adverse Events Occurring Within One Week of Stimulation Visit.
