Background:
Renal infarction is an uncommon complication of Blunt renal artery injury (BRAI) following abdominal trauma. Diagnosis of infarction is difficult and mostly delayed due to non-specific symptoms. Early diagnosis can lead to appropriate and effective treatment, which prevents further complication.
Case Presentation:
We report a case of 21-year-old man falling from a height of 9 m. A contrast-enhanced CT scan in the nephrogram phase showed no evidence of absorption in the right kidney and significantly decreased absorption in the left kidney. The pyelogram phase showed no secretion in the right kidney and decreased secretion in the left kidney suggesting segmental renal infarction. Subsequently, heparin infusion was initiated immediately. A follow-up contrast- enhanced abdominopelvic CT scan was performed after 1 month and showed no sign of infarction, and all laboratory tests were normal.
Conclusion:
Contrast-enhanced abdominopelvic CT scan helps physicians diagnose the renal infarction immediately and start appropriate treatment. Treatment can vary from aggressive surgical procedures to observation and supportive care.
