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.
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.
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.
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.
本研究旨在评估局部尿道内麻醉剂对患者在软性膀胱镜检查过程中所感受到疼痛的疗效。
对142例接受软性膀胱镜检查的男性患者进行了一项观察性、前瞻性、非随机研究。患者被分为两组：第1组：70例使用尿道内麻醉剂（2%利多卡因）的患者，第2组：72例未使用尿道内麻醉剂的患者。结果通过视觉模拟评分法和疼痛问卷进行评分并分析。使用SPSS 17.0进行统计分析，统计学显著性为p≤0.05。
第1组的平均年龄为64.7±10.3岁，第2组为66.7±10.8岁，无显著差异。第1组视觉模拟评分法的得分是2.23±2.20，第2组为1.69±1.74（p=0.1）。在疼痛问卷中，第1组的总体和当前疼痛强度分别为1.81±0.87和1.66±1.65，第2组分别为1.72±0.72和1.21±1.45（无显著差异）。根据视觉模拟评分法得分≤2将患者分组后，观察到导致膀胱镜检查的原因是与疼痛感知相关的独立因素，感知更多疼痛的风险增加1.89。
在软性膀胱镜检查前使用局部麻醉剂作为润滑剂似乎并不能减轻疼痛，我们认为不建议常规使用。
