Abstract
|
|
|
Despite current practice there is no evidence to demonstrate the efficacy of intraurethral 2% lidocaine gel as an anesthetic for rigid cystoscopy To evaluate the usefulness of lidocaine on decreasing pain associated with cystoscopy, we performed
a
randomized controlled study comparing 2% lidocaine gel with a plain water based lubricant. Pain was recorded on a visual analogue scale by the patient and by the physician. Physician perception of pain experienced by the patient was compared with
the
actual pain experienced. We found decrease in pain perception in men following lidocaine gel instillation with a 5 or 10 minute dwell time compared to instillation of the plain lubricant.
