使用尿道旋切刀治疗女性尿道闭锁

Management of female urethral obliteration with the rotary excision appliance

目的：介绍用尿道旋切刀治疗女性尿道闭锁的新方法,并评价其治疗效果.方法：自2000年10月至2013年7月,北京积水潭医院泌尿外科用尿道旋切刀治疗5例女性尿道闭锁患者（年龄23 ～ 65岁,平均43岁;病史3～ 60个月,尿道闭锁长度0.5～1.8 cm）,术后进行随访并评价治疗效果.结果：5例患者均能正常排尿,随访时间5 ～75个月,最大尿流率（maximal urinary flow rate,MFR） 15～ 28 mL/s,平均20.6 mL/s.3例患者无尿失禁,2例有轻度尿失禁.结论：尿道旋切术微创、简单、安全,是治疗女性尿道闭锁的有效方法.

Objective：To describe a new technique using the rotary excision appliance for the treatment of female urethral obliteration and to evaluate the effect of the management. Methods： Between October 2000 and July 2013, 5 cases of female urethral obstruction （age from 23 to 65 years, time to treatment from 3 to 60 months, obliteraion length from 0.5 to 1.8 cm） were managed using the rotary excision appliance and the patients had been followed up. Results： After a mean of 32.4 months （ range ： 5 to 75 months） of follow-up, normal micturation had been achieved in all the patients. The maximal urinary flow rate （MFR） ranged from 15 to 28 mL/s （mean 20.6 mL/s）. Three patients were continent and 2 patients had slight incontinence. Conclusion： The rotary excision appliance is a useful instrument for the management of female urethral obliteration. Our long-term follow-up provides further support for use of this technique by demonstrating that urethral continuity can be established without increased incidence of stricture formation or incontinence.
