1、万方数据硕士学位论文中文摘要平均(1．5-4-0．2)。进行为期3—17个月的随访观察，49例患者随访至今，失访1例，其中X<1cm的患者11例治愈，无复发：25例1cm3cm的患者中6例治愈或好转，7例复发，其中5例行尿道成形术，1例再次行球囊扩张器联合钬激光。23例单纯性尿道狭窄治愈或好转19例，成功率为82．6％；26例复杂性尿道狭窄治愈或好转t7例，成功率为65．4％，二者有明显差别(P<0．05)。术后均无尿道出血、尿道穿孔、尿瘘、尿失

2、禁、尿道膀胱结石等并发症发生。结论：1．球囊扩张器联合钬激光治疗尿道狭窄效果满意，且安全性可靠，并发症少，恢复时间快，值得进一步推广应用。2．其疗效与尿道狭窄的长度相关，X<1cm，球囊扩张器联合钬激光治疗效果确切，可作为首选；lcm3cm，应选择开放手术。3．球囊扩张器联合钬激光可作为治疗单纯性尿道狭窄首选方法，对复杂性尿道狭窄也具有明显效果。关键词：尿道狭窄；钬激光；球囊扩张器万方数据硕士学位论文英文摘要Theclinicalstudyofballoondilation
