Summary
Pediatric renal trauma, often from blunt force, requires prompt evaluation. Early diagnosis and treatment of kidney injuries in children can salvage the kidney in 90% of cases, avoiding nephrectomy.
Area of Science:
- Pediatric Traumatology
- Urologic Imaging
- Pediatric Nephrology
Background:
- Nonpenetrating trauma frequently causes renal injuries in children.
- Pre-existing renal abnormalities are present in 10% of pediatric kidney injury cases.
- Associated injuries, particularly to the brain and spleen, occur in about 40% of cases.
Purpose of the Study:
- To outline the diagnostic approach and management of pediatric renal injuries.
- To emphasize the importance of early recognition and intervention.
Main Methods:
- Clinical suspicion based on flank tenderness and hematuria.
- Radiographic evaluation including plain roentgenograms and infusion pyelography.
- Further imaging (renal scan, retrograde pyelography, aortography) for non-visualized kidneys.
Main Results:
- Bilateral contrast visualization indicates intact renal vessels.
- Renal contusion presents as reduced contrast with compression, no extravasation.
- Extravasation signifies disruption requiring surgical repair, with 90% kidney salvage.
- Delayed diagnosis of arterial occlusion leads to kidney death.
Conclusions:
- Renal injury should be suspected in children with flank tenderness and hematuria.
- Prompt radiographic evaluation is crucial for diagnosis and management.
- Early surgical intervention can salvage kidneys in most cases, minimizing the need for nephrectomy.
