OBJECTIVE: The aim of this study is to evaluate the efficacy of a local intraurethral anesthetic on the pain perceived by the patient during flexible cystoscopy.
METHODS: An observational, prospective, nonrandomized, study was conducted on 142 males subjected to a flexible cystoscopy. The patients were divided into two groups: Group 1: 70 patients with intraurethral anesthetic (lidocaine 2%), and Group 2:72 patients without intraurethral anesthetic. The results were scored on a visual analog scale and a pain questionnaire and analyzed. The statistical analysis was performed using SPSS 17.0 and with a statistical significance of p≤0.05.
RESULTS: The mean age of Group 1 was 64.7±10.3 years compared to 66.7±10.8 years in Group 2, with no significant differences. The score on the visual analog scale in Group 1 was 2.23±2.20 versus 1.69±1.74 in Group 2 (p=0.1). The overall and current pain intensity in the pain questionnaire was 1.81±0.87 and 1.66±1.65, respectively, in Group 1, and 1.72±0.72 and 1.21±1.45, respectively, in Group 2 (no significant differences). After dividing the patients into groups according to a visual analog scale score ≤2, it was observed that the cause that led to cystoscopy was an independent factor associated with the perception of pain, increasing the risk of perceiving more pain by 1.89.
CONCLUSION: The use of local anesthetic as a lubricant prior to flexible cystoscopy does not appear to reduce pain, and we consider that its routine use is not indicated.
