Q

Define Hypospadias.
With what other congenital anomaly may it also be associated?

Q

Define Epispadias.
With what TWO congenital anomalies may it also be associated?
What causes it?
How frequent?

A

Urethra opens on DORSAL (EPI= upon)

  • Asstd. w undescended testes + bladder Exstrophy
  • **Abnormal positioning of genital tubercle

-Much less common than hypospadias, needs corrected because it leads to recurrent infection.
