980nm半导体红激光汽化术在良性前列腺增生治疗中的应用

目的:探讨980 nm半导体红激光汽化术治疗良性前列腺增生(BPH)的安全性和疗效。方法:应用980 nm半导体红激光对92例BPH患者行激光汽化切除术。患者年龄65～89岁,平均前列腺体积为(50.1±13.0)ml,观察记录手术时间、出血量、手术并发症,记录并统计分析手术前后国际前列腺症状评分(IPSS)、生活质量评分(QOL)、最大尿流率(Qmax)及残余尿量(PVR)等指标的差异有无统计学意义。结果:手术全部成功,手术时间平均(70.2±16.9)min,术中无明显出血,无输血病例。患者术后留置尿管2～5 d,平均留置尿管时间(2.4±0.3)d,IPSS术后1个月为(8.7±2.0)分,3个月为(7.7±1.1)分,明显低于术前[(17.9±3.7)分,P<0.01],Qmax及PVR明显好于术前(P<0.01),无患者出现尿失禁及明显的膀胱刺激征。结论:980 nm半导体红激光汽化切除术治疗BPH是安全有效的。

980 nm diode laser vaporization for benign prostatic hyperplasia

Objective: To explore the efficacy and safety of 980 nm diode laser vaporization in the treatment of benign prostatic hyperplasia(BPH).Methods: We treated 92 BPH patients by 980 nm diode laser vaporization.The patients were aged 65-89 years,with a mean prostate volume of(50.1±13.0) ml.We analyzed and compared the mean operation time,intra-operative blood loss,postoperative complications,international prostate symptom score(IPSS),quality of life(QOL) score,maximum urine flow rate(Qmax),and post void residual(PVR) before and after surgery.Results: Operations were successful in all the 92 cases,with an average operation time of(70.2±16.9) min,very little blood loss and no blood transfusion.The transurethral catheter indwelling time was 2-5(2.4±0.3) days.The patients were followed up for 1 to 3 months,which revealed a significant reduction in IPPS(P<0.01) and improvement in Qmax and PVR(P<0.01) as compared with preoperation.No severe complications were reported,including urinary incontinence and bladder irritation symptoms.None of the patients complained of impaired erectile function.Conclusion: Transurethral 980 nm diode laser vaporization is a safe and effective treatment for BPH.
