【摘要】 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。更多还原

【Abstract】 Objective To investigate the effect of green light laser in complex posterior urethral stricture after surgical treatment of benign prostatic hyperplasia （BPH）.Methods Green light laser was applied in treating 20 cases of complex iatrogenic posterior urethral stricture.Of these cases,12 had false passages,5 had more than 2 strictures and 5 had concurrently urethratresia.The scar tissues were transure- thrally vaporized and resected.The in-dwelling urethral catheter time was 1-2 months after operation. Results All the patients were initially cured without serious complications.The mean operative time was 39 rain （range,30-65 min）.During the follow-up of 2-10 months,1 case had mild incontinence:another case (Q_max＜9ml/s 2 weeks after surgery) got satisfactory results(Q_max＞15ml/s)after the scheduled urethral dilatation.The other 18 cases were treated successfully and voided fluently with postoperative Q_max＞15ml/s in all.Conclusions It is suggested that transurethral green light laser procedure is not only safe and ef- fective,but also simple and minimally iuvasive for complex posterior urethral stricture following surgical treat- ment of BPH.更多还原
