Introduction:
In our center the level of division of the corpus spongiosum as the determinant to classifying hypospadias. The hypospadias with a distal division is less severe and they present a little curvature.
Material And Methods:
We present a case of distal hypospadias corrected by Koff technique and we showed our tricks for avoiding curvature.
Results:
In this selected case a Koff procedure are preferred because it has the main advantage of exicing the dysplastic tissues and avoiding a urethroplasty using nonurethral tissues. Late penile curvature is a source of concerns for some, but in our experience no significant curvature was found at follow up.
Discussion:
We believe that some tricks, showed in our video, are necessary to avoid iatrogenic curvature and to obtain a good cosmetic result.
Conclusions:
Koff technique is a good technique for hypospadias with distal division of corpus spongiosum, without significant curvature at follow up.
