I Contusion
Microscopic or gross haematuria, urologic studies normal
Subcapsular, nonexpanding without parenchymal laceration
II Haematoma
Nonexpanding perirenal haematoma confined to renal retroperitoneum
<1 cm parenchymal depth of renal cortex without urinary extravasation
III Laceration >1 cm parenchymal depth of renal cortex without collecting system rupture or urinary extravasation
IV Laceration
Parenchymal laceration extending through renal cortex, medulla and collecting system
Main renal artery or vein injury with contained haemorrhage
V Laceration
Completely shattered kidney
Avulsion of renal hilum that devascularises kidney
