ABSTRACT

Background: Cystoscopy constitutes a very helpful tool for diagnostic and treatment of multiple urologic diseases. In these days there is controversy in literature about the efficacy of local intraurethral anaesthetics for performing cystoscopy. Objective: To compare the effectiveness between intraurethral tetracaine and lidocaine for performing cystoscopy in men. Material and methods: Prospective, comparative, simple blind, randomized, clinical assay. A total of 60 patients were included in the study, randomly divided into 3 groups of 20 each. It was applied 0.5%, lidocaine 2% and placebo via intrauretral, according to groups, the patient was asked to determine the intensity of pain during the procedure according to visual analogue pain scale. Results: We found statistical significant difference between the tetracaine (p ‹ 0.001) and lidocaine (p = 0.003) versus placebo. No statistical significant difference was found between lidocaine and tetracaine (p = 0.377). Conclusion: It was found statistically significant decrease in pain caused by performing cystoscopy in men who received intraurethral tetracaine and lidocaine 5 minutes before the procedure, compared to placebo.
