目的:探讨自制导光尿道探子联合输尿管镜及电切镜在治疗男性创伤性尿道狭窄或闭锁中的作用和价值。方法:采用自制导光尿道探子及输尿管镜置入斑马导丝通过尿道狭窄或闭锁部位进入膀胱,再经斑马导丝引导筋膜扩张器扩裂尿道狭窄或闭锁部位,电切尿道瘢痕组织,留置F_(20)硅胶尿管4周。采用此方法治疗创伤性尿道狭窄或闭琐患者27例。结果:21例尿道狭窄患者经输尿管镜置入斑马导丝成功,6例尿道闭锁患者通过自制导光尿道探子建立通道,由输尿管导管引导置入斑马导丝成功。扩裂及电切治疗27例手术均获得成功,恢复正常排尿,其中2例尿道再狭窄者行尿道扩张治愈。结论:自制导光尿道探子联合输尿管镜及电切镜治疗男性创伤性尿道狭窄或闭锁操作简单、安全、有效,损伤小,并发症少,住院时间短,是一种理想的术式。
Objective: To explore the role and value of self-made guided urethral catheterization combined with ureteroscopy and resectoscope in the treatment of traumatic urethral stricture or atresia. Methods: The self-made light guide urethral probe and ureteroscopy into the zebra guide wire through the urethral stricture or atresia into the bladder, and then guided by the zebra guidewire fascia dilator crack urethral stricture or atretic site, cut urethral scar tissue, indwelling F_ (20) silicone catheter for 4 weeks. Twenty-seven patients were treated with this method for the treatment of traumatic urethral stricture or obstruction. Results: Twenty-one patients with urethral stricture were successfully treated with ureteroscope and zebra guidewire. Six patients with urethral atresia established the path through the self-made light-guided urethral probe, and the guide catheter was placed in the ureter to lead the zebra guidewire. 27 cases of operation were treated by dissection and electrotomy, all of which achieved normal urination. Two cases of urethral restenosis were cured by urethral dilatation. CONCLUSION: Self-made guided urethral catheterization combined with ureteroscopy and resectoscope is an ideal surgical procedure for the treatment of traumatic urethral stricture or atresia in men. It is simple, safe, effective, less damaging, less complications and shorter hospital stay.
