Normally, the urethra and vagina are separate in females. In rare cases a birth defect causes the urethra and vagina to become one. This is known as urogenital sinus.

There are 2 types of urogenital sinus abnormalities:

  • In a low confluence (joined) case:
    • The common opening is short
    • The urethra is close to its normal place
    • The vagina is almost normal length
  • In a high confluence case:
    • The common opening is long
    • The urethra is inside the body
    • The vagina is short
    • The anus can be too far forward
