The Effect of Intraurethral 2% Lidocaine Gel as Topical Urethral Anesthetic During Cystoscopy / 대한비뇨기과학회지

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.
