Abstract: Objective To evaluate anatomic traveling direction and CT findings of thickening of the bridge septa of perinephric space.Methods 75 cases of diseased samples were examined by CT, and CT signs of the thickened bridge septa of perirenal space were analyzed retrospectively.Results Thickening of the bridge septa of perinephric space was observed in three specific etiological groups:group one for renal diseases,in which there were renal trauma (26 cases),renal tuberculosis (2 cases),renal abscess (4 cases),pyelonephritis (3 cases), urinary tract obstruction (15 cases) and renal cancer (2 cases);group two for non-renal diseases, in which there were acute pancreatitis (15 cases), acute cholecystitis (1 case),peritonitis (2 cases) and colon cancer (3 cases);group three for unknown origin (2 cases).The images findings appeared as multiple stripes or branching shadows locating in the perinephric space.Conclusion The etiological factor of the bridge septa thickening is varied.CT can show the thickened bridge septa of perirenal space accurately,and identify the etiological factors.
