Zorluk: ZorUrologic Surgery

A 3434-year-old man is evaluated in the trauma bay following a high-velocity motorcycle collision. He is hemodynamically stable. Examination reveals lower abdominal guarding, diffuse tenderness, and a displaced pelvic ring fracture. Retrograde urethrography demonstrates an intact urethra, allowing for the safe placement of a urethral catheter, which yields 300 mL300\text{ mL} of frankly bloody urine. A subsequent retrograde CT cystography demonstrates contrast extravasation into the paracolic gutters and outlining loops of small bowel.

Arrange the following surgical management steps in the most appropriate chronological sequence for this patient.

  1. 1Perform an emergent exploratory laparotomy to access the peritoneal cavity
  2. 2Identify the bladder dome laceration and debride any devitalized tissue margins
  3. 3Execute a watertight, multilayered bladder repair using absorbable sutures
  4. 4Maintain continuous postoperative bladder decompression via a large-bore catheter
  5. 5Obtain a follow-up cystogram to verify complete healing prior to catheter removal

Cevap

The correct sequence for managing an intraperitoneal bladder rupture is to first perform an exploratory laparotomy, debride the devitalized tissue at the bladder dome, repair the defect in multiple layers using absorbable sutures, maintain continuous bladder decompression with a catheter, and finally verify healing with a cystogram before catheter removal.
The established standard of care for an intraperitoneal bladder rupture follows a strict surgical sequence: gaining access via laparotomy, preparing the injury site via debridement, performing a proper multilayer watertight closure using absorbable materials, protecting the repair postoperatively with continuous decompression, and radiographically confirming success prior to returning to normal physiologic function.

Adım Adım Çözüm

1
Diagnose the specific type of urologic injury based on imaging findings.
The presence of contrast outlining loops of small bowel confirms an intraperitoneal bladder rupture.
Intraperitoneal ruptures occur at the bladder dome and leak urine into the abdominal cavity, whereas extraperitoneal ruptures are confined to the pelvic space.
2
Determine the primary surgical approach.
An emergent exploratory laparotomy is indicated.
Intraperitoneal urine causes severe chemical peritonitis and systemic toxicity; the large defect will not heal with catheter drainage alone and requires open surgical exposure.
3
Sequence the intraoperative steps.
The surgeon must first debride devitalized tissue, then perform a multilayered repair using absorbable sutures.
Healthy margins are necessary for wound healing. Absorbable sutures are strictly required in all urinary tract surgeries to prevent permanent foreign bodies that lead to calculus (stone) formation.
4
Sequence the critical postoperative management steps.
The bladder is kept continuously decompressed with a catheter, followed by a confirmatory cystogram weeks later.
Continuous drainage prevents detrusor contractions and suture line tension. A cystogram ensures the defect is fully sealed before the catheter is safely removed and the bladder is allowed to fill natively.

Surgical management of intraperitoneal bladder rupture requires emergent exploratory laparotomy, debridement, multilayered repair with absorbable sutures, and prolonged postoperative catheter decompression followed by a confirmatory cystogram.
