Ureteral avulsion from non-penetrating trauma
The Journal of Urology
|January 1, 1981
Summary
Sudden trauma can cause complete ureteral avulsion, primarily in children, often due to trunk hyperextension. Prompt diagnosis and surgical repair, even if delayed, lead to successful outcomes for this ureteropelvic junction injury.
Area of Science:
- Urology
- Trauma Surgery
- Pediatric Surgery
Background:
- Acute acceleration/deceleration trauma can lead to severe internal injuries.
- Ureteral avulsion is a rare but serious consequence of blunt abdominal trauma.
Observation:
- Six cases of complete ureteral avulsion were identified in five patients following acute acceleration/deceleration trauma.
- The ureteropelvic junction was the most susceptible site for this disruption injury.
- One patient sustained an associated unsalvageable contralateral renal arterial intimal injury.
Findings:
- All ureteral avulsion injuries were successfully repaired.
- Four patients required only a single surgical procedure for repair.
- The injury mechanism appears to involve sudden hyperextension of the trunk, predominantly affecting children.
Implications:
- Despite its occult nature and potential to be masked by other injuries, ureteral avulsion requires persistent diagnostic effort.
- Timely surgical intervention, even when delayed, can yield satisfactory results for patients with ureteral avulsion.
- This study highlights the importance of considering ureteral avulsion in pediatric patients with significant trauma.
