Summary
The purpose of this study is tp evaluate the changes in stress induced Urethral Leak Point Pressures (LPP) and other urodynamic measurements in response to acute pudendal nerve stimulation (PNS) in patients with a pre-existing implanted urological neurostimulator stimulating the pudendal nerve.
Description
Patients with a neurostimulator implanted at the pudendal nerve will be enrolled and undergo urodynamic testing. Before testing, study staff will provide an oral antibiotic (to reduce the risk of infection) and adjust the stimulation settings with a goal to increase urethral pressure from baseline by at lest 20cm H2O, without causing the patient discomfort/distress. These settings will be used throughout urodynamics. Before filling the bladder, a urethral pressure profile study will be completed 3 times with stimulation off, then 3 times with stimulation on. Leak point pressure (LPP) testing will then be completed. The patient's bladder will be filled following standard urodynamic testing protocol. Filling will be paused every 50-100mL to complete LPP assessment. Subjects will be asked to complete a light cough, medium cough, forceful cough, and Valsalva maneuver (in that order). Detrusor pressure will be measured at each event, and staff will document whether or not a leak was elicited. This will be completed with stimulation off, then with stimulation on, as the bladder is filled. Once the subject reports a strong urge to void, urethral pressure profile assessment will be completed again: 3 times with stimulation off, then 3 times with stimulation on. Once urodynamic testing is complete and the patient's bladder is emptied, a measurement of urethral pressure will be completed with stimulation off, then during 5 seconds of stimulation, then again with stimulation off.
