A 28-year-old man falls from height and presents with left flank pain and gross haematuria. Contrast-enhanced CT shows a renal parenchymal laceration measuring 2 cm that does not involve the collecting system. There is a small stable perirenal haematoma. What is the AAST grade of this renal injury?
- A Grade I
- B Grade II
- C Grade III ✓
- D Grade IV
Correct answer: C. Grade III
Explanation
AAST Grade III denotes a parenchymal laceration greater than 1 cm in depth without extension into the collecting system and without evidence of urine leak. Grade II is a superficial laceration less than 1 cm. Grade IV requires extension into the collecting system or a segmental vascular injury, and the absence of urinary extravasation here excludes Grade IV.
