Contribution of Urethral Sensory Feedback in Voiding Efficiency

• Status: Completed
• Trial end date: 2018-12-21
• Target enrollment: 0
• Participant gender: Female

Summary

The purpose of this study is to evaluate how urethral anesthesia impacts voiding efficiency in healthy women. The investigator hypothesizes that anesthetizing the urethral with lidocaine gel will decrease voiding efficiency as measured by standard bladder testing (urodynamic testing).
