Abstract:
Objective To evaluate the curative efficacy of modified Koyanagi procedure for severe hypospadias.Methods The clinical data were retrospectively reviewed for Koyanagi operation (n=151) versus and Duckett’s procedure (n=188) for severe hypospadias from February 2009 to October 2018.The curative rates and complications of two operations were compared and the efficacy of modified Koyanagi operation was evaluated.Results In Koyanagi group,there were urinary fistula (n=17),urethral stricture (n=15),urethral diverticulum (n=2),urethral infection (n=3) and wound dehiscence (n=2); In Duckett group,urinary fistula (n=37),urethral stricture (n=27),urethral diverticulum (n=6),urethral infection (n=11) and wound dehiscence (n=6).The curative rate was significantly higher in Koyanagi group than that in Duckett group.And urinary fistula rate was significantly lower than that in Duckett group (P<0.05).Parental satisfaction with appearance was significantly lower than that of non-operative urologists (P<0.05).Conclusion The modified Koyanagi procedure is more convenient with fewer postoperative complications and better postoperative penile appearance.The curative efficacy is definite for severe hypospadias is accurate.Up to the international level,it may be employed as a new option for treating severe hypospadias.
