1470 nm双效能激光在前列腺增生症中的临床应用

Clinical Application of 1 470nm Double-Effect Laser Vaporizationin to Benign Prostatic Hyperplasia

目的探讨1 470 nm双效能激光汽化术治疗良性前列腺增生症的临床疗效。方法 2016年7月至2017年6月,应用1 470 nm双效能激光汽化术治疗良性前列腺增生症患者52例,汽化功率150 W。术后3~6个月随访,观察与分析手术前后国际前列腺症状评分(international prostate symptom score,IPSS)、生活质量指数(quality oflife,QOL)评分、最大尿流率(the maximum flow rate,Q_(max))及残余尿量(post-void residual volume,PVR)、手术时间、术前合并症及术后并发症,评价疗效。结果 52例前列腺增生症患者手术均获成功,手术时间20~82 min,平均(45. 0±12. 6)min。术后住院时间3~5 d,平均(3. 5±1. 2)d。术后IPSS评分、QOL评分、Q_(max)及PVR明显优于术前,差异均具有统计学意义(P<0. 05)。术中、术后均无明显并发症发生。结论 1 470 nm双效能激光汽化术是治疗中等大小前列腺增生患者安全有效的微创治疗方法,尤其对于高龄、高危患者具有手术时间短、出血少、恢复快、住院时间缩短等优势。

Objective To investigate the clinical efficacy of 1 470 nm double-effect laser vaporization in the treatment of benign prostatic hyperplasia.Methods Totally 52 patients of benign prostatic hyperplasia treated with 1 470 nm dual-function laser during the period from Jul.2016 to Jun.2017 were selected for the study.The international prostate symptom score(IPSS),quality of life score(QOL),maximum urinary flow rate(Qmax),residual urine volume(PVR),operation time,preoperative complications and postoperative complications before and after the surgery were observed and analyzed.The efficacy was evaluated after 3-6 months’follow-up.Results The 1 470 nm double-effect laser vaporization was conducted successfully for all the 52 patients.After the operation,the IPSS scores,QOL scores,Qmax and PVR were significantly improved.The differences of the indexes before and after the surgery were statistically significant(P<0.05).The operation time was 20-82 min,(45.0±12.6)min on average.The postoperative hospital stay lasted for 3-5 days,averaging(3.5±1.2)days.No significant complication occurred during or after the surgery.Conclusion The 1 470 nm double-effect laser vaporization is a safe and effective minimally invasive treatment for patients with moderate-grade benign prostatic hypeplasia.Especially for elderly patients and high-risk patients,it has the advantages of short operation time,less bleeding,quicker recovery,and shorter hospital stay.
