Summary

Successful hypospadias surgery relies on careful tissue handling and appropriate reconstruction techniques. Preservation of the urethral plate with an onlay graft is recommended for midshaft hypospadias, offering a low complication rate.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Reconstructive Surgery

Background:

  • Hypospadias repair requires meticulous surgical techniques to achieve optimal functional and cosmetic outcomes.
  • Choosing the correct surgical approach is crucial for minimizing complications.

Purpose of the Study:

  • To outline key principles for successful midshaft hypospadias surgery.
  • To discuss preferred techniques for urethral reconstruction and penile curvature correction.

Main Methods:

  • Review of surgical principles including minimal tissue handling, tension-free reconstruction, and use of well-vascularized tissue.
  • Evaluation of onlay grafts versus tubularized pedicle flaps for urethral reconstruction.
  • Assessment of ventral lengthening versus dorsal plication for penile curvature.

Main Results:

  • Preservation of the urethral plate with an onlay graft is associated with a low complication rate for midshaft hypospadias.
  • Tubularized pedicle flaps, while carrying higher risks of strictures, diverticula, and fistulas, are suitable for poorly developed urethral plates.
  • Ventral lengthening procedures are recommended for penile curvature to avoid compromising penile length.

Conclusions:

  • Adherence to principles of minimal tissue handling, tension-free repair, and appropriate technique selection leads to excellent outcomes in midshaft hypospadias.
  • Onlay grafts are a preferred method for urethral reconstruction when the urethral plate is adequate.
  • Ventral lengthening is advised for curvature correction in cases of compromised penile length.
