为研究确定前列腺扩张术对有症状前列腺增生症患者治疗作用,33个年龄为45岁到82岁的患有症状的BPH患者同意接受此项随机双盲研究。除其中2人失去随访外其余31人随机分成2组。接受扩张术的15人,接受膀胱镜检的16人。2组患者的年龄、前列腺体积、Boyarsky症状分数、最大尿流率、排尿量、残留尿等均相似。两组患者均在尿道灌注1%利多卡因和静脉镇静下进行前列腺扩张术或膀胱镜检
To study the role of prostate augmentation in the treatment of patients with symptomatic benign prostatic hyperplasia, 33 symptomatic BPH patients aged 45 to 82 years old agreed to receive this randomized, double-blind study. Except two of them, the remaining 31 were randomly divided into two groups. 15 patients undergoing dilatation and 16 undergoing cystoscopy. The age, prostate volume, Boyarsky symptom scores, maximal uroflow rate, urine output, and residual urine in both groups were similar. Both groups underwent urethral perfusion of 1% lidocaine and intravenous sedation for prostate augmentation or cystoscopy
