简介：目的：探讨2μm激光治疗长期口服抗凝药物良性前列腺增生患者的安全性及有效性。方法：对28例长期服用抗凝药物良性前列腺增生患者行经尿道前列腺2μm激光“刀削面”式汽化切除术。结果：手术时间为30～70min，平均时间（45±13）min；术后持续膀胱冲洗1～3d；留置尿管2～6d，膀胱造瘘管于拔出尿管后次日拔出；术后住院时间4～7d。术后随访3～6个月，术前与术后6个月平均IPSS分别为：（22.7±4.5）分、（6.8±3.5）分；QOL分别为：（5.2±0.4）分、（2.2±1.2）分；Qmax分别为：（6.4±1.5）mL／s、（18.8±3.2）mL／s，上述三项指标与术前比较，均有明显改善（P＜0.01）。结论：经过严格术前评估与恰当处理，2μm激光治疗长期口服抗凝药物良性前列腺增生患者安全有效。

简介：目的：探讨经尿道2μm激光前列腺剜除术后短暂性尿失禁最佳治疗方法。方法：对经尿道2微米激光前列腺剜除术后尿失禁患者80例,分成A、B、C、D四组,各20例,分别行观察等待、提肛肌功能训练,中药结合针炙治疗,盆底生物反馈结合提肛肌功能训练治疗,对尿失禁治疗效果分析比较。结果：A组患者术后尿失禁持续天为5~62d（18±2.4）d,B组患者术后尿失禁持续天为4~52d（17±1.8）d,C组患者术后尿失禁持续天为4~17d（9±1.2）d,D组患者术后尿失禁持续天为3~15d（8±0.8）d。结论：经尿道前列腺剜除术后并发尿失禁,中药结合针炙治疗和盆底生物反馈结合提肛肌功能训练治疗效果均较理想,明显优于单纯提肛肌功能训练及观察等待组。
