Brief Summary
OnabotulinumtoxinA (Botox®) bladder injections are a highly effective treatment for overactive bladder and urgency urinary incontinence. The procedure is typically performed in the office setting with one of two medications to control comfort. However, the effectiveness of these medications has never been compared. The goal of this study is to determine which medication is better at providing comfort during bladder Botox® injections.

Outcome Measures
Primary Outcomes (1)
Analgesic Effect Measured with 100mm Visual Analog Scale
The visual analog scale is a visual representation of pain severity rated from 0 (no pain) to 10 (worst pain imaginable). Therefore higher numbers represent more pain.The scale is represented visually using a 100 millimeter line and patients indicate their level of pain by pointing to a location on the line.

Study Arms (2)
Oral Phenazopyridine
ACTIVE COMPARATORPatients randomized to the oral phenzopyridine arm will receive 200mg phenazopyridine to take by mouth 1-2 hours before their scheduled procedure.
Intravesical Lidocaine
ACTIVE COMPARATORPatients randomized to the intravesical lidocaine arm will have the bladder back-filled with 30mL 2% lidocaine for the 20 minutes immediately preceding their procedure.
Interventions
200mg PO Phenazopyridine taken 1-2 hours prior to the Botox® injection procedure
30mL 2% lidocaine instilled into the bladder lumen 20 via a urinary catheter 20 minutes prior to the Botox® injection procedure
