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.
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 urethral dilation. A silicone catheter was reserved for 2 weeks after the dilation.
All the 12 patients achieved smooth urination after removal of the catheter. During the 6 - 28 months follow-up, 8 of the cases were cured after 1 - 6 regular urethral dilations and the other 4 experienced no more dysuria.
Urethral dilation with a zebra guidewire-guided fascia dilator is a safe and effective method for the treatment of complex urethral stricture after hypospadias surgery.
评估斑马导丝引导下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的临床效果。
本研究纳入12例尿道下裂术后复杂性尿道狭窄患者，这些患者对其他尿道扩张治疗无效。经耻骨上穿刺孔置入输尿管镜，将斑马导丝经输尿管镜送入尿道，然后沿斑马导丝插入筋膜扩张器进行尿道扩张。扩张后留置硅胶导尿管2周。
12例患者拔管后均排尿通畅。随访6～28个月，8例经1～6次规律尿道扩张后治愈，4例排尿困难症状未再出现。
斑马导丝引导下筋膜扩张器尿道扩张术是治疗尿道下裂术后复杂性尿道狭窄的一种安全有效的方法。
