Randomized Controlled TrialPatient tolerance during cystoscopy: a randomized study comparing lidocaine hydrochloride gel and dimethyl sulfoxide with lidocaine.
Cystoscopy is one of the most common examinations in urologic outpatient clinics. Various anesthetic approaches have been used to make cystoscopy more tolerable for patients. The aim of the present prospective randomized study was to evaluate the efficacy of lidocaine hydrochloride gel compared to dimethyl sulfoxide (DMSO) with lidocaine in rigid cystoscopy. ⋯ Our study has shown that DMSO with lidocaine gel causes significantly less delivery discomfort in the male urethra than lidocaine hydrochloride gel. The advantages of DMSO with lidocaine are the mixture takes less time to act and had lower pain scores.
