Match each clinical presentation of genitourinary trauma with the most appropriate next step in management or definitive treatment.

  • A 28-year-old man with a pelvic fracture; retrograde cystography shows a 'flame-like' pattern of contrast extravasation confined to the perivesical space.Urethral catheter drainage and observation
  • A 35-year-old woman with a seatbelt sign; retrograde cystography shows contrast extravasation outlining loops of the small intestine.Immediate laparotomy and surgical repair
  • A 42-year-old man with blunt flank trauma; CT scan reveals a 2.5-cm renal cortical laceration without urinary extravasation.Conservative management with bed rest and serial hemoglobin monitoring
  • A 22-year-old man with a straddle injury; examination reveals a 'butterfly' perineal ecchymosis and blood at the external urethral meatus.Retrograde urethrography

Cevap

The correct matches align specific mechanisms of genitourinary trauma and imaging findings with their standard surgical or conservative management guidelines.
Each trauma presentation requires a specific algorithm: extraperitoneal bladder ruptures are managed with catheter drainage, intraperitoneal ruptures require surgical closure, stable renal lacerations are observed, and suspected urethral injuries mandate retrograde imaging before attempting catheterization.

Adım Adım Çözüm

1
Identify the type of bladder rupture in the first two scenarios.
The first scenario is extraperitoneal ('flame-like' contrast). The second scenario is intraperitoneal (contrast outlining bowel).
Differentiation between extraperitoneal and intraperitoneal rupture dictates operative versus non-operative management.
2
Determine the definitive management for each bladder rupture.
Extraperitoneal requires catheter drainage; Intraperitoneal requires laparotomy and surgical repair.
Intraperitoneal urine causes chemical peritonitis and reabsorption of urea/creatinine, mandating formal surgical closure.
3
Assess the renal trauma severity in the third scenario.
The scenario describes a low-to-intermediate grade renal laceration without a urinary leak or hemodynamic instability.
Hemodynamically stable low-grade renal injuries are safely managed conservatively.
4
Recognize the signs of urethral injury in the fourth scenario.
The presentation of a straddle injury with a butterfly hematoma and blood at the meatus strongly suggests a bulbar urethral injury. Management is retrograde urethrography.
Blind catheterization is contraindicated as it can convert a partial urethral tear into a complete transection.
