经尿道等离子柱状电极治疗后尿道狭窄疗效观察

Effective observation on transurethral plasma cylindrical electrode for treating posterior urethral stricture

目的:观察经尿道等离子柱状电极治疗后尿道狭窄的疗效。方法:经尿道等离子柱状电极治疗后尿道狭窄、闭锁23例的临床资料进行术后分析。结果:23例手术均获成功,随访6～12个月,19例自行排尿通畅。最大尿流率>15 mL/s,2例6个月后复发行,二次等离子柱状电极治愈,2例1年内定期尿道扩张。结论:经尿道等离子柱状电极治疗后尿道狭窄及闭锁,具有疗效显著、并发症少、再发狭窄少等优点,是治疗创伤性后尿道狭窄安全、有效的腔内手术方法。

Objective：To evaluate the curative effect of transurethral plasma cylindrical electrode in the treatment of posterior urethral stricture.Methods：The clinical data in 23 cases of transurethral plasma cylindrical electrode for treating posterior urethral stricture and atresia were performed the postoperative analysis.Results：All cases succeeded in operation and were followed up for 6-12 months.19 cases had smooth voiding by themselves.The maximum urine flow rate（Qmax）15 mL/s.2 cases performed the second plasma cylindrical electrode treatment due to recurrence after 6 months.2 cases performed regular urethral dilation within 1 year.Conclusion：Transurethral plasma cylindrical electrode for treating posterior urethral stricture and atresia has the distinct curative effects with advantages of fewer complications and less restricture,which is safe and effective endoscopic operative method to treat traumatic posterior urethral stricture.
