Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Clinical Indicators
High suspicion scenarios
- Gross hematuria + pelvic fracture
- Inability to void with suprapubic pain
- Penetrating lower abdominal injury
- Blood at urethral meatus (check urethra first)
- 85% of blunt bladder injuries have pelvic fracture
- 10% of pelvic fractures have bladder injury
03Decision Urethral Injury Suspected?
Blood at meatus, high-riding prostate, perineal ecchymosis
04Action Retrograde Urethrogram First
Must rule out urethral injury before catheter
- NEVER catheterize if urethral injury suspected
- RUG to evaluate urethral integrity
- If intact: proceed with catheter + cystogram
- If disrupted: suprapubic tube
05Action CT Cystography
Gold standard for bladder injury (AUA Strong Rec)
- Fill bladder with 350mL dilute contrast
- Adequate distension critical (false negatives if underfilled)
- Post-drainage images essential
- Look for: intra vs extraperitoneal leak
- Combined injury in 5-10%
06Decision Type of Bladder Rupture?
Determines management pathway
07Warning Intraperitoneal Rupture
REQUIRES SURGICAL REPAIR (AUA Strong Rec)
- Contrast in peritoneal cavity
- Usually dome rupture (weakest point)
- More common with full bladder + blunt trauma
- Risk of peritonitis, urinary ascites
- Cannot manage with catheter alone
08Action Surgical Repair
Open or laparoscopic cystorrhaphy
- Two-layer closure with absorbable suture
- Debride devitalized tissue
- Water-tight closure
- Leave suprapubic or urethral catheter
- Drain pelvic space
- Concurrent procedures if laparotomy
09Action Follow-Up Cystogram
Before catheter removal
- Typically 10-14 days post-injury/repair
- Earlier if clinical concern (sepsis, leak)
- If healed: remove catheter
- If leak persists: continue drainage
- Re-image in 1-2 weeks if persistent
10Warning Potential Complications
Monitor and manage
- Persistent leak: extend catheter drainage
- Infection/sepsis: IV antibiotics
- Fistula formation (rare with prompt treatment)
- Incontinence (rare, usually resolves)
- Small bladder capacity (if delayed diagnosis)
11Outcome Expected Outcomes
Excellent with appropriate management
- Healing rate >95% with proper treatment
- Extraperitoneal: >85% heal with catheter alone
- Surgery success rate >98%
- Long-term bladder function usually normal
12Action Extraperitoneal Rupture
Catheter drainage usually sufficient (AUA Strong Rec)
- Contrast confined to pelvis
- Associated with pelvic fracture
- Lateral/anterolateral bladder wall
- Most heal with catheter drainage alone
- Exception: bladder neck injury, bone in bladder
13Action Catheter Management
Large bore Foley drainage
- 18-22 Fr Foley catheter
- Keep bladder decompressed
- Monitor urine output
- Antibiotics controversial (AUA: selective use)
- Duration: 10-14 days typically
- Path rejoins step 09Shared downstream outcome
14Action Combined Rupture
Both intra and extraperitoneal
- Occurs in 5-10% of bladder injuries
- Treat as intraperitoneal (surgery)
- Repair both components
- More complex injury pattern
- Path rejoins step 08Shared downstream outcome
- Path rejoins step 05Shared downstream outcome
