Incidence

Definition and Description

Hypospadias (hypo = below; spadon = a fissure or a ‘hole’)  is a ventral displacement of the urethral meatus and may be associated with:

  • Incomplete formation of the prepuce / foreskin (dorsal 'hooding')
  • Ventral curvature (chordee).

Urethral meatal openings are generally described as being:

  • Anterior – where the meatus is near the tip of the penis
  • Middle – where the meatus is along the shaft of the penis
  • Posterior – where the meatus is near the base of the penis or in the scrotum

 

  • Early recognition and paediatric urological referral is useful for counselling and planning timing of surgery
