Renal Columns Necrosis

Renal columns necrosis is a medical condition affecting the kidneys, specifically the renal columns. This guide provides a detailed yet simple overview of renal columns necrosis, covering its definitions, causes, symptoms, diagnostic methods, treatments, and more.

Renal columns necrosis refers to the death of cells in the renal columns, which are extensions of the kidney’s cortex that lie between the renal pyramids in the medulla. This condition can impair kidney function and is often associated with various kidney diseases.

Pathophysiology

Structure

• Renal Columns: Areas of kidney tissue that support the renal pyramids.
• Function: Help in the exchange of nutrients and waste between the cortex and medulla.

Blood Supply

• Arteries: Supplied by branches of the renal artery.
• Blood Flow: Essential for delivering oxygen and nutrients to kidney tissues.

Nerve Supply

• Autonomic Nervous System: Regulates blood flow and kidney function.
• Sensory Nerves: Detect pain and other sensations in the kidneys.

Types of Renal Columns Necrosis
