顺行导丝引导筋膜扩张器尿道扩张术治疗尿道下裂术后复杂性尿道狭窄

目的:探讨顺行置入导丝引导筋膜扩张器行尿道扩张术治疗尿道下裂术后复杂性尿道狭窄的临床疗效。方法:对其他尿道扩张方法治疗失败的尿道下裂术后复杂性尿道狭窄12例,经耻骨上膀胱造瘘孔放入输尿管镜,经输尿管镜将斑马导丝置入尿道,顺斑马导丝逐号置入筋膜扩张器进行尿道扩张。术后放置硅胶气囊尿管2周。结果:12例均获成功,拔尿管后排尿通畅,随访6~28个月,其中8例定期常规方法尿道扩张1~6次后治愈,另4例不再出现排尿困难。结论:顺行置入导丝引导筋膜扩张器行尿道扩张术是治疗尿道下裂术后复杂性尿道狭窄安全有效方法。

Urethral dilation with a zebra guidewire-guided fascia dilator for complex urethral stricture after hypospadias surgery

Objective: To evaluate the clinical effect of urethral dilation with a zebra guidewire-guided fascia dilator in the treatment of complex urethral stricture after hypospadias surgery.Methods: This study included 12 cases of complex urethral stricture after hypospadias surgery that had failed to respond to other urethral dilation therapies.A zebra guidewire was put into the urethra via a ureteroscope placed in through a suprapubic puncture hole.Then a fascia dilator was inserted along the zebra guidewire for ...
