Management of Bladder Perforation
Intraperitoneal bladder ruptures require immediate surgical repair, while uncomplicated extraperitoneal bladder ruptures can be managed with catheter drainage alone. This fundamental distinction drives all management decisions and directly impacts patient outcomes including mortality from peritonitis and sepsis 1, 2.
Initial Assessment and Hemodynamic Considerations
In hemodynamically unstable patients:
- Insert urethral or suprapubic catheter as a temporary measure
- Postpone definitive bladder repair until the patient is stabilized 2
- Address life-threatening injuries first using damage control principles
- For severe intraperitoneal ruptures during damage control, use urinary diversion via bladder and perivesical drainage 2
In hemodynamically stable patients, proceed with definitive management based on injury type.
Intraperitoneal Bladder Rupture
Surgical exploration and primary repair is mandatory 1, 2. These are typically large "blow-out" injuries at the bladder dome from blunt trauma that will not heal spontaneously. Failure to repair leads to bacterial translocation, peritonitis, and sepsis 1.
Surgical approach:
- Open repair remains the standard 1, 2
- Laparoscopic repair is appropriate for isolated injuries in hemodynamically stable patients without other indications for laparotomy 2
- Use two-layer closure with monofilament absorbable suture (single-layer acceptable laparoscopically) 2
- Confirm integrity of bladder neck and ureteral orifices during repair 1
Important caveat: While guidelines universally recommend surgery, one recent 2025 case report 3 describes successful conservative management of an intraperitoneal rupture. However, this represents an extreme outlier and should not change standard practice given the high risk of peritonitis and sepsis.
Extraperitoneal Bladder Rupture
Uncomplicated injuries:
Catheter drainage is the treatment of choice 1, 2, 4. These injuries heal with conservative management in over 85% of cases within 10 days 2.
- Insert urethral Foley catheter (suprapubic catheter offers no advantage in adults) 1
- Leave catheter for 2-3 weeks standard duration 1, 4
- Perform follow-up cystography to confirm healing 1, 4
- Consider open repair if non-healing after >4 weeks of catheter drainage 1, 4
Complicated extraperitoneal injuries requiring surgical repair 1, 2:
- Bladder neck injuries (may not heal with catheter alone)
- Exposed bone spicules in bladder lumen from pelvic fractures
- Concurrent rectal or vaginal lacerations (risk of fistula formation)
- Large extraperitoneal injuries 5
- Adjacent orthopedic implants or external pelvic fixators 5
- When patient is already undergoing laparotomy for other injuries or orthopedic fixation 1, 2
Penetrating Bladder Injuries
All penetrating injuries require surgical repair regardless of intraperitoneal vs extraperitoneal location 2. These are commonly through-and-through injuries requiring complete pelvic inspection. Gunshot wounds frequently involve concurrent rectal injury requiring fecal diversion 2.
Post-Repair Management
- Urethral catheter alone is sufficient (no suprapubic tube needed in adults) 1, 2
- Exception: Suprapubic catheterization recommended in pediatric patients 2
- Urethral catheters provide adequate drainage with shorter hospital stay and lower morbidity compared to combined urethral/suprapubic drainage 1
Follow-up cystography:
- Required for complex repairs and extraperitoneal injuries managed conservatively 1
- May not be necessary for simple intraperitoneal repairs 1
- Perform before catheter removal to confirm healing 4
Common Pitfalls to Avoid
Missing intraperitoneal component: Always perform proper cystography with adequate bladder distention (>300 mL contrast) 5. CT cystography is preferred diagnostic modality.
Attempting conservative management of intraperitoneal ruptures: This risks life-threatening peritonitis and sepsis 1.
Routine suprapubic tube placement: Multiple studies show no advantage over urethral catheter alone in adults 1.
Premature catheter removal: Ensure 2-3 week minimum drainage and confirm healing with cystography before removal 1, 4.
Missing associated injuries: During repair, always inspect bladder neck, ureteral orifices, and check for concurrent rectal/vaginal injuries 1, 2.
