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.
