[edit] Discussion and CT Cystography Findings

Intraperitoneal bladder rupture

  • Occurs in approximately 10%–20% of major bladder injuries.
  • Typically the result of a direct blow to the already distended bladder.
  • CT cystography demonstrates intraperitoneal contrast material around bowel loops, between mesenteric folds, and in the paracolic gutters


Extraperitoneal bladder rupture

  • Most common type of bladder injury (80%–90% of cases).
  • Usually caused by penetrating trauma
  • In blunt trauma, the presumed mechanism is direct laceration of the bladder by bone fragments from a pelvic fracture.
  • CR cystography reveals a variable path of extravasated contrast material.


Combined bladder rupture

  • Simultaneous intraperitoneal and extraperitoneal injury.
  • CT cystography usually demonstrates extravasation patterns that are typical for both types of injury.
