目的 探讨半导体激光间织内凝固治疗良性前列腺增生症（BPH）的临床应用优势及价值。rn方法 应用强生830e组织间插入式半导体激光治疗仪进行激光间织内凝固（ILC）治疗高龄、高危BPH患者70例，大多数患者伴有1～2种慢性疾病，例如冠心病、慢性支气管炎、肺气肿、慢性肾功能不全、糖尿病、脑出血、脑梗死后遗症等。随访6～12个月，分别于术前、术后1、2、3与6个月进行国际前列腺症状评分（IPSS）和生活质量评分（QOL），并测定最大尿流率（Qmax）和残余尿量以评价其疗效。rn结果 治疗后6个月，IPSS达6.2±2.2，QOL为2.0±0.2，Qmax和残余尿量分别为17.2 ml/s±2.1 ml/s和10.2 ml±2.4 ml，与术前比较上述各项指示有明显改善，疗效显著(P＜0.001)。rn结论 半导体激光治疗BPH具有损伤小、安全性高和并发症少等优点，术后2～3个月以后有效率可达100%，是目前治疗BPH中较有前途的方法之一。“,”Objective To probe into the minimal invasive prostatectomy.rnMethods 70 cases of benign prostatic hyperplasia(BPH), the age from 65 to 91 years old, of high risk have been treated by transurethral prostatectomy with indigo 830e interstitial laser coagulation(ILC), most of the patients with one or two kinds of chronic disease such as coronary heart disease, chronic bronchitis, pulmonary emphysema, chronic renal insufficiency, diabetes, sequelae of cerebral hemorrhage and cerebral infarction. The patients have been followed up for 6-12 months. The treatment effect was evaluated by international prostate symptom score(IPSS), quality of living(QOL), maximal flow rate (Qmax) and residual urine.rnResults At 6 months after therapy, the IPSS score was 6.2±2.2, the QOL score was 2.0±2.2, Qmax was 17.2 ml/s±2.1 ml/s andrnresidual urine 10.2 ml±2.4 ml.rnConclusions The benefits of the diode laser treatment for BPH were less damage, high security and less complication. the best result could be achieved in 2-3 months after the procedure and the effective rate reaches 100%.
