Abstract

PURPOSE
The this study was performed to evaluate whether the extent and location of retroperitoneal hematoma correlate with the severity of renal injury.
MATERIALS AND METHODS
We evaluated the CT findings of 27 patients with renal trauma. The retroperitoneal hematoma were subdivided into perirenal hematoma(PRH), anterior pararenal hematoma(APH), posterior pararenal hematoma(PPH) and interfascial hematoma(IFH) The perirenal hematoma (PRH) was classified as grade I, II and III according to the amount of hematoma.
RESULTS
PRH was present in all 27, PPH in 8, IFH in 3 patients and APH was not observed. Grade I PRH was present in 7 (70%) of 10 minor injury (contusion, intrarenal hematoma), grade Ill PRH in 2(20%) of 10 minor injury and in 7 (41.2%) of 17 major and catastrophic injury (laceration, fracture, shattered kidney and renal pedicle injury). Eight PPH were present only in the major and catastrophic injury and 3 IFH in each of intrarenal hematoma, laceraton and pedicle injury.
CONCLUSION
The location and extent of PRH and PPH correlated somewhat with the severity of renal injury, while the presence of IFH and APH did not correlate with severity of the renal inury.
