Difficulty: Very hardUrologic Surgery

Match each clinical presentation of a urologic injury or surgical complication to its most appropriate definitive management or immediate next step.

  • A 42-year-old man with a pelvic fracture has gross hematuria. CT cystography reveals contrast extravasation confined to the retropubic space. No other injuries are identified.Urethral Foley catheter drainage for 10 to 14 days
  • A 35-year-old man presents with acute abdominal pain following a seatbelt injury. CT cystography demonstrates contrast material outlining the loops of the small intestine.Exploratory laparotomy with primary two-layer bladder closure
  • A 28-year-old man with a crush pelvic fracture presents with blood at the urethral meatus. Retrograde urethrography shows contrast extravasation at the bulbomembranous junction.Suprapubic cystostomy placement with delayed urethroplasty
  • A 45-year-old woman develops a continuous, clear vaginal discharge two weeks after a radical hysterectomy. CT urography shows right-sided hydronephrosis and contrast pooling in the vagina.Urinary diversion via percutaneous nephrostomy with delayed ureteral reimplantation
  • A 31-year-old woman presents with fever and flank pain 3 days after ureteroscopy. CT reveals a 4-cm retroperitoneal fluid collection and contrast extravasation from the distal ureter.Ureteral stent placement and percutaneous fluid drainage

Answer

Extraperitoneal bladder rupture requires urethral Foley catheter drainage. Intraperitoneal bladder rupture requires exploratory laparotomy with primary closure. Posterior urethral injury requires suprapubic cystostomy placement. Ureterovaginal fistula requires urinary diversion via percutaneous nephrostomy. Ureteral injury with urinoma requires ureteral stent placement and percutaneous fluid drainage.
Each clinical presentation is uniquely matched to its guideline-directed surgical or conservative management based on the specific anatomical location of the injury and the timeline of the presentation.

Step-by-Step Solution

1
Analyze the imaging findings to classify the anatomical location of the bladder injury.
Contrast confined to the retropubic space indicates extraperitoneal rupture, whereas contrast outlining bowel loops indicates intraperitoneal rupture.
Management of bladder trauma strictly depends on the relationship of the rupture to the peritoneal reflection.
2
Determine the optimal initial intervention for suspected urethral injuries.
Avoid blind urethral catheterization and place a suprapubic cystostomy.
Catheterization can convert a partial urethral tear into a complete transection.
3
Evaluate the timeline and presentation of the iatrogenic ureteral injuries to guide surgical timing.
Recognize that a 2-week-old ureterovaginal fistula is highly inflamed, requiring diversion (nephrostomy) rather than immediate reconstruction. An infected urinoma needs active drainage alongside internal stenting.
Operating on acutely inflamed, friable tissue leads to high failure rates in reconstructive urologic surgery, and undrained collections lead to sepsis.

Key Concept

The management of urologic trauma and post-surgical complications relies on accurate anatomical diagnosis (intra- vs. extraperitoneal, anterior vs. posterior urethra) and avoiding interventions that exacerbate the injury or risk sepsis.
