Minor Calyx Hematoma

Pathophysiology

Structure

• Kidneys: Two bean-shaped organs responsible for filtering blood.
• Minor Calyx: Small tubes that collect urine from the kidney’s nephrons.

Blood Supply

• Renal Artery: Supplies blood to the kidneys.
• Interlobar and Arcuate Arteries: Branches that provide blood to the minor calyx.

Nerve Supply

• Renal Plexus: A network of nerves that helps regulate kidney functions.
