Background
- 90% of non-iatrogenic injuries occur from penetrating injury
- Isolated ureter injury is rare
Clinical Features[1]
- Symptoms usually nonspecific
- Hematuria present in ~70%
- Delayed signs of occult injury include:
- Fever/sepsis, flank pain, ileus, urinary leakage or obstruction
- Complications include :
- Peritoneal or retroperitoneal urinary leakage
- Perinephric abscess
- Fistula formation (e.g. ureterovaginal, uterocutaneous)
- Ureteral stricture/obstruction
Differential Diagnosis
Abdominal Trauma
- Abdominal compartment syndrome
- Diaphragmatic trauma
- Duodenal hematoma
- Genitourinary trauma
- Liver trauma
- Pelvic fractures
- Retroperitoneal hemorrhage
- Renal trauma
- Splenic trauma
- Trauma in pregnancy
- Ureter trauma
Evaluation
- Absence of hematuria does NOT rule out ureteral injury
- If CT is nondiagnostic but high index of suspicion perform IV urography or retrograde pyelography
Management
- Surgery
Disposition
- Admit
