Why can we see a sharp demarcation between the cortex and the medulla in shock kidney?

Why can we see a sharp demarcation between the cortex and the medulla in shock kidney?

What is the pathomechanism that govern the process of acute renal failure that causes that morphological sign?

Thank you all.

Acute tubular necrosis is the most common cause of Acute Renal Failure in Shock.

The demarcation is due to blood pooling in the cortex so the cortex is hyperaemic and the medulla is anaemic.
