Cortical Nephron Hematoma

Pathophysiology

Structure

• Nephron: The basic structural and functional unit of the kidney responsible for filtering blood and forming urine.
• Cortex: The outer part of the kidney where most nephrons are located.
• Hematoma: A localized? collection of blood outside blood vessels, usually due to injury or bleeding disorders.

Blood Supply

• The kidneys receive blood through the renal? arteries, which branch into smaller arterioles supplying the nephrons.
• A hematoma can compress these blood vessels, reducing blood flow and affecting kidney function.

Nerve Supply

• The kidneys are innervated by the autonomic nervous system, which controls blood flow and filtration rates.
• Nerve irritation from a hematoma can cause pain? and disrupt normal kidney signaling.
