Summary
The study will be a double-blind randomized control trial comparing 4% lidocaine patch placed
over the sacrum 1 hour prior to a percutaneous nerve evaluation (PNE) procedure to a placebo
patch in patients already scheduled to undergo a medically indicated percutaneous nerve
evaluation (PNE). VAS pain score, The volume of injectable lidocaine used, Patient
Satisfaction Score, rate of successful PNE (defined as successful placement of wire in the S3
spinal foramen), and the amplitude of perineal stimulation on a Likert scale will be
collected immediately after the procedure. Patients will follow up in 1 week - as is standard
of care with the PNE procedure. Adverse events such as pain or change in sensation will be
recorded. Number of voids and incontinence episodes per day after the PNE procedure will be
recorded. Overall satisfaction score will be recorded at that time. Rate of progression to
Sacral nerve stimulator implantation will be collected.
We hypothesize that patients in the lidocaine patch group will experience significantly less
pain at the time of PNE as measured by a lower change in VAS pain score when compared with
the control group.
