Urethral dilation with a zebra guidewire-guided fascia dilator for complex urethral stricture after hypospadias surgery / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
