Abstract
INTRODUCTION:Topical urethral analgesia with 2% lignocaine gel for office procedures is an accepted practice in contemporary urology. However, instillation of 2% lignocaine gel into the urethra is associated with discomfort in some patients. MATERIAL AND METHODS:Forty consenting men reporting for cystoscopy under local anesthesia were randomized to receive 10 ml of 2% lignocaine hydrochloride gel at 4 degrees C and 22 degrees C. After instillation of the gel the patients were immediately asked to score the pain using a nongraphical visual analogue scale. RESULTS: The pain scores were analyzed using the paired Student's t-test. There was significant reduction in pain scores in the group receiving gel at 4 degrees C compared with the group at 22 degrees C (P < 0.05). CONCLUSION: Refrigerating the gel to 4 degrees C can significantly reduce the initial discomfort associated with instillation of 2% lignocaine hydrochloride into the male urethra.
