MCQ
4. A patient sustains significant trauma after a fall from 4 stories. As a part of their trauma imaging you obtain a CT Cystogram (Picture). What would be your next management?
a) Insert a suprapubic catheter and observe on the ward
b) Insert a urethral catheter and observe on the ward
c) Observe on ward and watch for signs of deterioration prior to consideration of emergency surgery
d) Insert a urethral catheter and ask an interventional radiologist to insert a drain into the peritoneal cavity to drain any urine
e) Take the patient for an emergency exploratory laparotomy and perform a two-layer bladder wall closure

Bladder injury scale (EAU adaptation from AAST)
Grade Description
I Haematoma Contusion, intramural hematoma
Laceration Partial thickness

III Laceration Extraperitoneal (>2 cm) or intraperitoneal (<2 cm) bladder wall laceration
IV Laceration Intraperitoneal bladder wall laceration >2 cm
V Laceration Intraperitoneal or extraperitoneal bladder wall laceration extending into the bladder neck or ureteral orifice (trigone)
Urethral injuries
• Classification by mode– Traumatic– Iatrogenic
• Classification by relation to urogentinal diaphragm– Anterior– Posterior
Urethral trauma. Part I: introduction, history, anatomy, pathology, assessment and emergency management

IV Complete disruption Extravasation of contrast at injury site without visualisation in the bladder, < 2 cm of urethral seperation
V Complete disruption Complete transection with >2 cm urethral seperation or extension into the prostate or vagina
Urethral injury (American associatoin for Surgery of Trauma )

III Partial disruption of anterior or posterior urethra
Extravasation of contrast at injury site with contrast visualised in proximal urethra or bladder
IV Complete disruption of anterior urethra
Extravasation of contrast at injury site without visualisation of proximal urethral or bladder
V Complete disruption of posterior urethra
Extravasation of contrast at injury site without visualisation of bladder
VI Complete partial disruption of posterior urethra with associated tear of the bladder neck or vagina
