[Modified prepuce-degloving repair for urethrocutaneous fistula following hypospadias surgery]

To investigate the clinical effect and application value of the modified method of prepuce-degloving repair (PDR) in the treatment of urethrocutaneous fistula (UCF) following hypospadias surgery.We retrospectively analyzed 87 cases of UCF caused by hypospadias repair from May 2001 to December 2011, of which 61 were treated by simple closure or Y-V plasty of the fistula (group A), and the other 26 by modified PDR (group B). We compared the success rate of surgery and long-term recurrence between the two groups.The total success rates of repair were 78.7 and 96.2% in groups A and B, respectively. Thirteen cases in group A did not respond to surgery, of which 6 failed to be cured by the second operation but later were treated successfully by modified PDR. In comparison, there was only 1 case of failure in group B, which was cured by a second PDR.Modified PDR can significantly improve the success rate and reduce the recurrence rate of UCF after hypospadias surgery, which deserves wide clinical application.
