Separation of renal fragments by a urinoma after renal trauma: percutaneous drainage accelerates healing.
BACKGROUND
Two boys suffered blunt abdominal trauma resulting in renal injury. In both cases the damaged kidney was fractured through its mid-portion, and the upper and lower fragments of the kidney became widely separated by a urinoma.


METHODS
US-guided drainage of the urinoma resulted in immediate apposition of the renal fragments. The drains were left on free drainage by gravity for 1 week before removal.


RESULTS
The urinomas did not reaccumulate and follow-up DMSA scans showed good residual function.


CONCLUSIONS
We suggest that drainage of urinomas that separate renal fragments should be considered since this may accelerate healing and help preserve renal function.
