RENAL MASSES PRESENTING 25 AND 50 YEARS FOLLOWING BLUNT RENAL TRAUMA

The long-term consequences of blunt renal trauma are not well describe d. We report on 2 patients with a history of blunt renal trauma who pr esented with radiographically detected renal masses suspicious for ren al tumor. Both patients suffered blows to the kidney during boxing mat ches followed by flank pain and hematuria, The injuries occurred 25 an d 50 years prior to the detection of renal masses. Subsequent nephrect omy and histopathological evaluation revealed benign dystrophic renal tissue. These presentations represent probable long-term sequelae of b lunt renal trauma.
