目的探讨输尿管镜下钬激光内切开联合筋膜扩张器在男性尿道狭窄治疗中的临床应用。方法骶管麻醉或表面麻醉下用F8/9.8输尿管镜检查尿道狭窄情况,直视下将斑马导丝通过狭窄段尿道置入膀胱,钬激光内切开尿道狭窄段瘢痕组织并在其引导下选择适宜的筋膜扩张器依次递增扩张尿道,再更换金属扩张器依次扩张,其后留置尿管,定期随访。结果全部病例1个月后拔除尿管后排尿症状较治疗前明显改善,术后尿道扩张期间排尿通畅,无并发症出现。结论鉴于输尿管镜下钬激光内切开联合筋膜扩张器进行尿道扩张具有多种优点,选择合适的病例采用此法治疗尿道狭窄是可行的。 Objective To investigate the clinical application of ureteroscopic holmium laser incision combined with fascia dilatation in the treatment of male urethral stricture. Methods The urethral stricture was examined by F8 / 9.8 ureteroscopy under caudal anesthesia or surface anesthesia. The zebra guidewire was inserted into the bladder through the narrow urethra under direct vision. The holmium laser was used to incise the scar tissue of the urethral stricture and guided by it Appropriate fascia dilator followed by increasing the expansion of the urethra, followed by replacement of metal dilators followed by expansion, followed by catheter placement, regular follow-up. Results All cases 1 month after removal of the catheter voiding symptoms were significantly improved than before treatment, urinary tract obstruction during postoperative urethral patency, no complications. Conclusion In view of ureteroscopic holmium laser incision combined with fascia dilator for urethral dilatation has many advantages, select the appropriate case of this method is feasible to treat urethral stricture.
