A single session of transurethral microwave thermotherapy using Prostatron (Technomed International, France) was performed in 20 patients with benign prostatic hyperplasia, and the clinical efficacy of this modality was evaluated by analysing the subjective and objective responses following the treatment. 1,296 MHz microwaves are delivered to the prostate by an antenna placed in a 20 Fr urethral balloon catheter equipped with a cooling system for preservation of the urethral mucosa. The treatment was performed in a single session for an hour on an outpatient basis. The clinical efficacy was evaluated by a total score of subjective symptoms and objective findings including residual urine and average flow rate, 8 weeks after the treatment. Reduction of subjective symptom score was observed in 26 cases (86.7%), and that of objective findings in 21 (70%). When 25% or more decrease of the total score was defined as good, the overall good result including subjective and objective responses was seen in 24 cases (80%). During the treatment and follow-up period, no severe adverse effect was detected. In conclusion, a single session of thermotherapy by Prostatron is a safe and useful modality as a non-surgical treatment performed on an outpatient basis for benign prostatic hyperplasia.
对20例良性前列腺增生患者进行了单次经尿道微波热疗（使用法国Technomed International公司的Prostatron设备），并通过分析治疗后的主观和客观反应来评估这种治疗方式的临床疗效。1296兆赫的微波通过放置在配备有冷却系统以保护尿道黏膜的20F尿道球囊导管中的天线传输至前列腺。治疗在门诊进行，单次疗程为1小时。治疗8周后，通过主观症状和客观检查结果（包括残余尿量和平均尿流率）的总分来评估临床疗效。主观症状评分降低的有26例（86.7%），客观检查结果降低的有21例（70%）。当总分降低25%或更多被定义为良好时，主观和客观反应的总体良好结果在24例（80%）中可见。在治疗和随访期间，未检测到严重不良反应。总之，单次使用Prostatron进行热疗作为一种门诊非手术治疗良性前列腺增生的方法是安全且有用的。
