目的:探讨经尿道钬激光治疗男性尿道狭窄的方法、安全性和疗效。方法:对38例男性尿道狭窄患者行经尿道狭窄段疤痕钬激光切除(功率10~45W),狭窄段长度:<1.0cm者18例,1.0~1.5cm者9例,>1.5cm者7例,完全闭锁者4例,并发膀胱结石者6例。平均最大尿流率为(5.6±2.3)ml/s。结果:36例手术成功,无大出血、尿外渗、直肠损伤等并发症发生,术后平均最大尿流率为(17.5±3.4)ml/s,2例中转开放手术,32例获随访3~18个月,其中4例行定期尿道扩张,2例以钬激光行二次手术后治愈。结论:经尿道钬激光治疗男性尿道狭窄安全、有效、创伤小、可重复治疗。
Objective: To explore the method, safety and curative effect of transurethral holmium laser to treat male urethral stricture. Methods: 38 patients with urethral stricture underwent transurethral resection of the scar by holmium laser (power 10 ~ 45W). The length of the stenosis segment was less than 1.0cm in 18 patients, 1.0 ~ 1.5cm in 9 patients and> 1.5cm in 7 patients. Completely blocked in 4 cases, complicated by bladder stones in 6 cases. The mean maximum flow rate was (5.6 ± 2.3) ml / s. Results: The operation was successful in 36 cases without complication of hemorrhage, exudation of urine and rectum injury. The mean maximal urinary flow rate after operation was (17.5 ± 3.4) ml / s, 2 cases were transferred to open surgery and 32 cases were followed up for 3 ~ 18 months, of which 4 cases of regular urethral dilatation, 2 cases of holmium laser line after the second cure. Conclusion: Transurethral holmium laser treatment of male urethral stricture is safe, effective, less trauma, repeatable treatment.
