Abstract
Introduction: Topical urethral analgesia with 2%lignocaine gel for office procedures is anaccepted practice in contemporary urology.However, instillation of 2% lignocaine gelinto the urethra is associated with discomfort insome patients.Material and Methods: Forty consentingmen reporting for cystoscopy under localanesthesia were randomized to receive 10 ml of2% lignocaine hydrochloride gel at 4 °Cand 22 °C. After instillation of the gel thepatients were immediately asked to score thepain using a nongraphical visual analogue scale.Results: The pain scores were analyzedusing the paired Student's t-test. There wassignificant reduction in pain scores in thegroup receiving gel at 4 °C compared with thegroup at 22 °C (P < 0.05).Conclusion: Refrigerating the gel to 4 °Ccan significantly reduce the initial discomfortassociated with instillation of 2% lignocainehydrochloride into the male urethra.
