目的探讨细输尿管镜联合筋膜扩张器在尿道下裂术后尿道狭窄治疗中的临床疗效。方法回顾性分析14例尿道下裂术后尿道狭窄患儿,用F5/7.6输尿管镜直视下将斑马导丝通过狭窄段尿道置入膀胱,在其引导下选择适宜的筋膜扩张器依次递增扩张尿道,其后留置尿管,并定期随访。结果本组14例患者均成功完成尿道扩张,拔除尿管后排尿通畅、尿线粗,最大尿流率明显提高,无假道形成、尿瘘、尿失禁等并发症出现。结论细输尿管镜联合筋膜扩张器治疗尿道下裂术后尿道狭窄具有创伤性小、安全性高、疗效确切、可重复性等优点,值得推广。
Objective To investigate the clinical effect of fine ureteroscope combined with fascia dilator in the treatment of urethral stricture after hypospadias operation. Methods A retrospective analysis of 14 cases of urethral stricture in children with hypospadias surgery, the use of F5 / 7.6 ureteroscope under direct vision of the urethra into the bladder through the narrow urethra, under its guidance select the appropriate fascia dilator sequentially increased Expand the urethra, followed by indwelling catheter, and regular follow-up. Results All the 14 patients completed urethral dilatation. The ureter was unobstructed after removing the catheter, the thick urine and the maximal uroflow rate were significantly increased. No complications such as fistula formation, urinary fistula or incontinence were found. Conclusions Fine ureteroscopy combined with fascia dilator for the treatment of urethral stricture urethral stricture with traumatic small, high safety, efficacy, reproducibility, etc., it is worth promoting.
