Application of microsurgical technique to prevent hypospadias repair from urethrocutanious fistula

Objective To enhance the curative effect of one -stage urethroplasty of hypospadias and to reduce the surgical complications of urethrocutanious fistula.Methods One-stage urethroplasties were carried out with microsurgical technique in17cases of hypospadias.The surgical methods consisted of onlay island flap urthroplasty(in4cases),transverse island flap urethroplasty(Duckett method,in8cases),and bladder mucosa urthroplasty(in5cases).Results The hypospadias were successfully repaired in all patients with no fistula or other serious complication s.The mean operation time was290min(ranging from240min to390min).Conclusion One-stage urethroplasty of hypospadias with microsurgical technique is highly effective,especially in reducing complication of urethrocutanious fistula.
