진단 및 손상 정도 평가 : 조영증강 CT

Grade	Type of Injury	Injury Description
I	Contusion	Microscopic or gross hematuria, normal urologic studies
I	Hematoma	Non-expanding subcapsular hematoma without parenchymal laceration
II	Hematoma	Non-expanding perirenal hematoma confined to retroperitoneum
II	Laceration	<1.0cm superficial cortical laceration without collecting system injury
III	Lacerations	>1.0cm deeper lacerations without collecting system injury
IV	Laceration	Parenchymal laceration extending through renal cortex, medulla and collecting system
IV	Vascular Injury	Main renal artery or vein injury with contained hemorrhage
V	Laceration	Completely shattered kidney with devascularization
V	Vascular Injury	Avulsion or thrombosis of renal hilum that devascularizes the kidney
* Advance one grade for bilateral injuries up to grade III

A: grade 1, subcapsular hematoma/contusion, without laceration

B: grade 2, non-expanding peri-renal hematoma confined to perirenal fascia

C: grade 3

D: grade 4, parenchymal laceration extending through renal cortex, medulla

E: grade 4, laceration involving the collecting system with extravasation

F: grade 5, shattered kidney

G: grade 5, avulsion of renal hlum that devascularises kidney
