120W/2μm铥激光前列腺汽化剜除术治疗BPH的疗效观察

Curative effect of 120W/2μm Thulium∶YAG laser vapoenucleation of the prostate therapy BPH

目的:探讨120W/2μm铥激光前列腺汽化剜除术(ThuVEP)的安全性及疗效。方法:应用120 W连续波2μm ThuVEP治疗BPH患者59例,分析患者术前资料及围术期情况,并对相应并发症进行评估。结果:患者平均前列腺体积(59.6±29.6)ml,平均手术时间(96.2±26.9)min,剜除时间(40.6±25.7)min,平均保留尿管时间(5.7±1.0)d。59例术后3个月随访效果良好。手术前后生活质量(QOL)评分为(4.5±1.2)∶(1.5±0.9)分,国际前列腺症状(IPSS)评分为(22.5±6.9)∶(4.9±1.3)分,最大尿流率为(7.9±4.6)∶(25.2±11.3)ml/s,剩余尿量为(148.6±76.5)∶(23.5±28.6)ml。2例术后需输血治疗。并发尿道狭窄2例。结论:120 W/2μmThuVEP治疗BPH是安全有效的,且并发症较少。

Objective：To evaluate the safety and efficacy of 120 W/2 μm Thulium ： yttrium-aluminium-garnet （YAG） vapoenucleation of the prostate （ThuVEP） for patients with benign prostate hyperplasia. Method： In total, 59 consecutive patients undergoing ThuVEP at our institution were evaluated prospectively. ThuVEP was carried out using the 120 W/2 μm continuous-wave Tm ： YAG laser. Patient perioperative and 3 month follow-up data were analysed. The complications were assessed. Result： Mean preoperative prostate volume was （59. 6 ± 29. 6） ml. Total operation time averaged（96.2±26.9） min, and the enucleation time was （40.6±25.7） min. The mean catheter time was （5.7± 1.0） days. All patients were available for review at the 3-month follow-up mark. Quality of life （4.5± 1.2） ： （1.5±0.9）, international prostate symptom score （22.5±6.9） ： （4.9±1.3）, maximum urinary flow rate （7.9±4.6） ： （25.2±11.3） ml/s and postvoiding residual urine （148.6±76.5） ： （23.5±28.6） ml. Two patients needed blood transfusions postoperatively. Urethral stricture developed in 2 respectively of the patients. Conclusion： 120 W/2 μm ThuVEP is a safe and efficacious procedure for the treatment of symptomatic benign prostatic obstruction. The incidence of complications with ThuVEP was low.
