Urethral Diverticulum


General Considerations

  • Much more common in females than males, in whom they are rare
    • Most often in women 30-50 years of age
    • In males, they are believed to be congenital; in females, most are acquired
  • Relatively common in women, especially with recurrent genitourinary infections, post-void dribbling and dyspareunia
  • Described as an outpouching of tissue from the posterior wall of the urethra (usually) into the urethrovaginal potential space
    • Lining of diverticulum is identical to urethral mucosa
  • Most are thought to be derived from dilated paraurethral ducts or gland
