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.
