Objective To evaluate the effectiveness and safety of retrograde urethral catheterization via flexible cystoscopy or rigid cystoscopy in patients with benign prostatic hyperplasia. Methods One hundred and thirty-two patients with benign prostatic hyperplasia, needing retrograde urethral catheterization via cystoscopy were randomly divided into 2 groups, 66 patients in each group. Group A was via flexible cystoscopy and Group B via rigid cystoscopy. The success rate, catheterizing time-consuming, visual analogue scale pain scores and related complication rate were compared between the 2 groups. Results There were no significant differences in age, disease type of the upper urinary tract, prostatic volume and catheterizing time-consuming between the 2 groups. The success rate of Group A was 93.9%, significantly higher than that of Group B (60.6%). The incidence of gross hematuria, acute urinary retention, lower urinary tract symptoms and fever were 3.0% vs 31.9%, 0% vs 13.6%, 4.5% vs 36.3%, and 6.0% vs 34.8% in the two groups respectively. There was significant difference between them. Conclusion Retrograde urethral catheterization via flexible cystoscopy applied to patients with benign prostatic hyperplasia is effective and safe.%目的 探讨软性和硬性膀胱镜下逆行输尿管置管在前列腺增生患者中应用的有效性和安全性.方法 132例需行膀胱镜下逆行置管的前列腺增生患者随机分为2组,每组66例,分别行软性膀胱镜和硬性膀胱镜下逆行输尿管置管,比较两组的置管成功率、置管时间、视觉模拟疼痛评分和相关并发症的发生率.结果 两组患者年龄、上尿路疾病类型、前列腺体积、置管时间比较,差异均无统计学意义(P＞0.05).软镜组置管成功率(93.9％),大于硬镜组(60.6％),(P＜0.05).软镜组和硬镜组的视觉模拟疼痛评分分别为(3.0±1.1)分和(7.8±1.5)分,置管后增加的肉眼血尿发生率分别为3.0％和31.9％,急性尿潴留发生率分别为0％ (0/66)和13.6％ (9/66),尿路刺激症状发生率分别为4.5％和36.3％,发热发生率分别为6.0％和34.8％,以上各项指标两组间比较差异均有统计学意义(P＜0.05).结论 软性膀胱镜下逆行输尿管置管应用于前列腺增生患者是安全、有效的.
