Match each presentation of genitourinary trauma or iatrogenic injury with its most appropriate definitive surgical or clinical management step.
- During an exploratory laparotomy for abdominal trauma, a 1.5-cm transection is identified in the proximal third of the ureter.Primary ureteroureterostomy over a double-J stent
- During a complex pelvic exenteration, a complete distal ureteral avulsion is recognized 2 cm from the ureterovesical junction.Ureteroneocystostomy, potentially utilizing a psoas hitch
- A patient develops high fever, leukocytosis, and an expanding pelvic urinoma on postoperative day 6 following a difficult hysterectomy.Percutaneous nephrostomy tube placement and image-guided fluid drainage
- Computed tomography shows a deep renal laceration extending into the collecting system with contrast extravasation in a hemodynamically stable patient.Conservative management with strict bed rest and serial clinical monitoring
Answer
Proximal ureteral transection matches with primary ureteroureterostomy; distal ureteral avulsion matches with ureteroneocystostomy; delayed post-op ureteral leak with urinoma matches with percutaneous nephrostomy and drainage; and stable Grade IV renal laceration matches with conservative management.
Appropriate urologic trauma management requires tailoring the intervention to the anatomy. Proximal injuries retain enough healthy tissue for end-to-end anastomosis. Distal injuries lack distal vascularity, necessitating bladder reimplantation. Delayed, infected presentations require a damage-control approach (diversion via nephrostomy) rather than definitive repair. Stable renal trauma requires observation, reserving surgery for instability.
Step-by-Step Solution
Key Concept
Surgical management of genitourinary trauma and iatrogenic ureteral injury depends strictly on anatomic location, time of recognition, and patient hemodynamic stability.
