Loop of Henle necrosis refers to the death of cells in the Loop of Henle, a critical part of the kidney’s nephron. The Loop of Henle plays a vital role in concentrating urine and maintaining the body’s water and salt balance. When necrosis occurs here, it can severely impact kidney function and overall health.
The Loop of Henle is a part of the nephron in the kidneys responsible for concentrating urine and reabsorbing water and salts. Necrosis refers to the premature death of cells in living tissue. Therefore, Loop of Henle necrosis means that the cells within this part of the kidney have died, potentially leading to impaired kidney function.
Pathophysiology
Structure
The Loop of Henle consists of three parts:
- Descending Limb: Extends into the medulla and allows water to leave the filtrate.
- Thin Ascending Limb: Permeable to salts, allowing their reabsorption.
- Thick Ascending Limb: Actively transports salts out of the filtrate.
Blood Supply
The Loop of Henle receives blood through:
- Vasa Recta: Specialized capillaries that surround the Loop, crucial for maintaining the kidney’s concentration gradient.
- Renal Arteries: Branch into smaller arterioles supplying the nephrons.
Nerve Supply
Nerves regulating the Loop of Henle are part of the autonomic nervous system, controlling blood flow and filtration rates.
Types of Loop of Henle Necrosis
- Ischemic Necrosis: Due to reduced blood flow.
- Toxic Necrosis: Caused by harmful substances or toxins.
- Infectious Necrosis: Resulting from severe infections.
- Traumatic Necrosis: Due to physical injury to the kidneys.
- Metabolic Necrosis: Caused by imbalances in body chemistry.
