Renal laceration

Case contributed by Dr Heather Pascoe


Stab to lower flank. Depth of 4 to 5 cm. Tachycardia.

Patient Data

Age: 30 years
Gender: Male

There is a 2 cm laceration in the lower pole of the left kidney. Associated small perinephric hematoma. Although arterial phase scanning not performed, there no CT features to suggest active bleeding.

Subcutaneous stranding is seen extending posterolaterally toward a region of slightly thickened skin, showing presumably the wound entry site.

No free fluid in the abdomen or pelvis. No pneumoperitoneum. The adjacent descending colon is unremarkable.

The liver, spleen, right kidney, adrenals, pancreas, bladder, bowel and gallbladder are unremarkable. The visualized lung bases are clear with no pneumothorax or pulmonary contusion seen.

Case Discussion

Given the length (2 cm) of the renal laceration, this is classified as an AAST grade III injury.
