Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action Clinical Indicators
Classic signs of urethral injury
- Blood at urethral meatus (most reliable)
- Inability to void
- Perineal/scrotal ecchymosis (butterfly)
- High-riding or non-palpable prostate
- Pelvic fracture present
- Straddle mechanism injury
03Warning ⚠️ DO NOT BLINDLY CATHETERIZE
Critical: May convert partial to complete disruption
- NEVER attempt urethral catheter if injury suspected
- One gentle attempt may be acceptable if trained
- If resistance: STOP immediately
- Proceed to imaging before any urethral instrumentation
04Action Retrograde Urethrogram (RUG)
Gold standard for diagnosis (AUA Strong Rec)
- Insert small catheter tip into fossa navicularis
- Inject 20-30mL dilute contrast
- Obtain oblique fluoroscopy images
- Look for: contrast extravasation, complete disruption
- Partial injury: some contrast reaches bladder
- Complete: no contrast above injury
05Decision Anterior or Posterior Injury?
Location determines mechanism and management
06Action Anterior Urethral Injury
Penile or bulbar urethra
- Mechanism: straddle injury, instrumentation, blunt
- Bulbar urethra most common site
- Penile urethra: direct trauma, fracture-related
- Usually no pelvic fracture association
- Perineal/scrotal butterfly ecchymosis classic
07Decision Partial or Complete Disruption?
Determines initial management approach
08Action Partial Urethral Injury
Some urethral continuity preserved
- Contrast reaches bladder on RUG
- Gentle catheter attempt may succeed
- Use small caliber (14-16 Fr) catheter
- If passes easily: leave in place 2-3 weeks
- If resistance: SPC
- Many heal without stricture
09Action Long-Term Follow-Up
Monitor for complications
- Voiding symptoms: flow rate, hesitancy
- Stricture recurrence: may need repeat surgery
- Erectile dysfunction: 20-60% with PFUI
- Incontinence: 2-20% depending on injury
- Urethroscopy if symptoms develop
10Outcome Expected Outcomes
Variable by injury severity
- Anterior partial: excellent prognosis
- PFUI: 50-100% stricture rate
- Urethroplasty success: >90%
- ED and incontinence dependent on injury severity
11Action Suprapubic Catheter Placement
Urinary diversion
- Open or percutaneous approach
- Ultrasound guidance if bladder not distended
- Confirm bladder distension before percutaneous
- 12-14 Fr catheter typically
- Allows definitive management planning
12Action Early Endoscopic Realignment
Within 7-14 days of injury
- Combined antegrade/retrograde approach
- Pass guidewire across disruption
- Place catheter over wire
- May reduce stricture severity
- Does not eliminate stricture risk
- Consider if patient stable for OR
- Path rejoins step 09Shared downstream outcome
13Action Delayed Urethroplasty
Definitive repair at 3+ months
- Allow inflammation to resolve
- RUG + VCUG to delineate stricture
- Anastomotic urethroplasty for short strictures
- Substitution urethroplasty if long gap
- Success rate >90% at experienced centers
- Path rejoins step 09Shared downstream outcome
14Action Complete Urethral Disruption
No urethral continuity
- No contrast above level of injury
- Requires suprapubic catheter (SPC)
- Options: Immediate realignment OR delayed repair
- Early realignment: lower stricture rate
- Delayed repair: 3+ months, definitive urethroplasty
- Both approaches acceptable (AUA)
- Path rejoins step 11Shared downstream outcome
15Action Posterior Urethral Injury
Membranous or prostatic urethra (PFUI)
- Mechanism: pelvic fracture (shearing force)
- Membranous urethra at urogenital diaphragm
- 1.6-25% of pelvic fractures have PFUI
- Associated with bladder injury in 10-20%
- Higher risk of incontinence/ED
- Path rejoins step 07Shared downstream outcome
