目的探讨腔内绿激光治疗良性前列腺增生术后复杂性后尿道狭窄的疗效。方法采用绿激光治疗良性前列腺增生术后复杂性后尿道狭窄患者20例,其中伴有假道者12例、伴2处以上狭窄者5例、合并尿道闭锁者5例；行经尿道瘢痕汽化切除,术后留置导尿管1～2周。结果20例患者手术均一次成功,手术时间30～65 min,平均39 min。随访2～10个月,18例一次治愈,排尿通畅,最大尿流率(Q_(max))均＞15 ml/s；1例拔除尿管后2周尿线变细,Q_(max)＜9 ml/s,行定期尿道扩张6个月后治愈,Q_(max)＞15 ml/s；轻度尿失禁1例。结论经尿道绿激光汽化治疗良性前列腺增生术后复杂性后尿道狭窄安全有效,手术操作简便,并发症少。
Objective To investigate the curative effect of intracavitary green laser in the treatment of complex posterior urethral stricture after benign prostatic hyperplasia. Methods Twenty patients with complicated posterior urethral stricture were treated with green laser in 12 patients with benign prostatic hyperplasia. Of them, 12 were accompanied by prosthesis, 5 were with 2 or more stenosis and 5 were complicated with urethral atresia. Postoperative catheter 1 to 2 weeks. Results All the 20 patients were operated successfully. The operation time ranged from 30 to 65 minutes with an average of 39 minutes. All the patients were followed up for 2 to 10 months. Eighteen patients were cured at one time and their urination was unobstructed. The maximal urinary flow rate (Q max) was> 15 ml / 9 ml / s. The patients were cured after 6 months of regular urethral dilatation. Q max (max)> 15 ml / s. One case of mild urinary incontinence. Conclusions Transurethral vaporization of green laser is safe and effective in the treatment of complex posterior urethral stricture of benign prostatic hyperplasia. The operation is simple and the complications are few.
