OBJECTIVE
To evaluate the effect of endourethrotomy with thulium laser as a minimally invasive treatment for urethral stricture.
METHODS
We treated 36 cases of urethral stricture or atresia by endourethrotomy with thulium laser, restored the urethral continuity by vaporization excision of the scar tissue, and observed the clinical effects and complications.
RESULTS
The mean operation time was 35 min, ranging from 10 to 90 min. Smooth urination was achieved after 2-6 weeks of catheter indwelling, with no urinary incontinence. The patients were followed up for 4-24 (mean 12) months, during which 27 did not need any reintervention, 5 developed urinary thinning but cured by urethral dilation, 3 received another laser urethrotomy for previous negligence of timely urethral dilation, and the other 1 underwent open urethroplasty.
CONCLUSION
Thulium laser urethrotomy is a safe and effective minimally invasive option for short urethral stricture, which is also suitable for severe urethral stricture and urethral atresia. Its short-term outcome is satisfactory, but its long-term effect remains to be further observed.
目的
评估铥激光尿道内切开术作为尿道狭窄微创治疗方法的效果。
方法
我们采用铥激光尿道内切开术治疗36例尿道狭窄或闭锁患者，通过汽化切除瘢痕组织恢复尿道连续性，并观察临床效果及并发症。
结果
平均手术时间为35分钟，范围为10至90分钟。留置导尿管2至6周后排尿通畅，无尿失禁。患者随访4至24个月（平均12个月），期间27例无需再次干预，5例出现尿道变细但经尿道扩张治愈，3例因先前未及时进行尿道扩张而再次接受激光尿道内切开术，另1例行开放性尿道成形术。
结论
铥激光尿道内切开术是治疗短段尿道狭窄的一种安全有效的微创选择，也适用于严重尿道狭窄和尿道闭锁。其短期效果令人满意，但长期效果仍有待进一步观察。
