Management of Urinary Catheter-Induced Urethral Injury

Immediate Management: Secure Urinary Drainage

The American College of Surgeons recommends establishing urinary drainage immediately via either urethral catheter or suprapubic catheter, then pursuing conservative management with delayed definitive repair for most injuries, reserving immediate surgical repair only for hemodynamically stable penetrating injuries without life-threatening associated trauma 1, 2, 3
Attempt gentle urethral catheter placement first if there is no contraindication and the injury appears partial, as recommended by the World Journal of Emergency Surgery 2
Place a suprapubic catheter if urethral catheterization fails or if there is complete urethral disruption, as suggested by the World Journal of Emergency Surgery 1, 2, 3

Perform retrograde urethrography to define the extent and location of injury, with a diagnostic accuracy of 95.9%, as recommended by the Journal of Urology 4
Repeat urethrography every two weeks until complete healing is documented, as suggested by the World Journal of Emergency Surgery 1, 2, 3

For anterior urethral injuries, initial conservative management with urinary drainage is the treatment of choice, as recommended by the World Journal of Emergency Surgery 1, 2, 3
For posterior urethral injuries, conservative management with planned delayed surgical treatment is recommended, as suggested by the World Journal of Emergency Surgery 1, 2, 3
For penetrating injuries, immediate direct surgical repair is recommended for uncomplicated penetrating anterior urethral injuries in hemodynamically stable patients, as recommended by the World Journal of Emergency Surgery 1, 2, 3

The rate of stricture after primary realignment of posterior injuries ranges from 14-100%, with most patients eventually requiring repeated instrumentation or formal urethroplasty, as reported by the Journal of Urology 4

Use urethrography or ureteroscopy for follow-up imaging, as recommended by the World Journal of Emergency Surgery 3, 5
Perform urethrography every two weeks until complete healing is documented for blunt anterior injuries, as suggested by the World Journal of Emergency Surgery 1, 2, 3

Blood at the urethral meatus mandates retrograde urethrography after pelvic or genital trauma, as recommended by The Journal of Urology 6
The retrograde urethrogram will demonstrate whether this is a partial or complete urethral disruption, guiding definitive management, according to The Journal of Urology 7

Never blindly pass another urethral catheter through the injured meatus, as this can convert a partial injury to complete urethral disruption, as warned by The Journal of Urology 7

For complete disruption or failed catheterization, the American Urological Association recommends placing a suprapubic catheter immediately, with small caliber percutaneous catheters requiring upsizing if there is hematuria or prolonged use anticipated 8
Avoid repeated catheterization attempts, as this increases injury severity and delays drainage, according to the American Urological Association 8

For posterior urethral injuries, the American Urological Association recommends suprapubic tube placement with delayed urethroplasty, as immediate sutured repair is associated with high rates of erectile dysfunction and urinary incontinence 8, 9
Primary realignment may be considered in hemodynamically stable patients within the first few days, but only by experienced urologists in a proper operating room setting, according to the American Urological Association 8

The American Urological Association recommends monitoring all patients for complications, such as stricture, erectile dysfunction, and incontinence, for at least one year following urethral injury 8

The American Urological Association advises against prolonged or heroic attempts at endoscopic realignment, as this increases injury severity without improving long-term outcomes 8
Delaying establishing urinary drainage is also a critical pitfall, as trauma resuscitations involve aggressive hydration requiring close volume monitoring, according to the American Urological Association 8
