There was patient of Kidney trauma with hematuria. Which of the following investigation is advised to localised the site of hematuria
Show Hint
In trauma with haematuria, think of which modality can simultaneously image the parenchyma, collecting system, and active bleeding in one scan.

- CT
- X-ray
- MRI
- USG
Show Solution
The Correct Option is A
Solution and Explanation
Scenario: Renal trauma with haematuria
Investigation to localise site of haematuria = CT (Computed Tomography)
Specifically: CT IVP (CT Intravenous Pyelogram) with three phases:
AAST Renal Trauma Grading (based on CT):
Why not others: X-ray cannot image parenchyma; USG misses collecting system injuries; MRI not practical in emergency.
\[\boxed{\text{Answer: CT}}\]
Investigation to localise site of haematuria = CT (Computed Tomography)
Specifically: CT IVP (CT Intravenous Pyelogram) with three phases:
- Arterial phase: detects active arterial extravasation
- Venous/nephrographic phase: identifies parenchymal lacerations and extent of injury
- Delayed/excretory phase: identifies collecting system disruption and ureteric injuries
AAST Renal Trauma Grading (based on CT):
- Grade I: renal contusion or subcapsular haematoma
- Grade II: non-expanding perirenal haematoma, laceration $<1$ cm depth
- Grade III: laceration $>1$ cm without collecting system rupture
- Grade IV: laceration extending into collecting system, vascular injury
- Grade V: shattered kidney or avulsion of renal hilum
Why not others: X-ray cannot image parenchyma; USG misses collecting system injuries; MRI not practical in emergency.
\[\boxed{\text{Answer: CT}}\]
