A nephron abscess is an infection that occurs in the kidneys, specifically within the nephron—the basic functional unit of the kidney. This condition can lead to serious health issues if not addressed promptly. In this article, we will explore its pathophysiology, types, causes, symptoms, diagnostic tests, treatments, surgeries, and prevention methods, as well as when to seek medical attention.
Pathophysiology
Structure of the Nephron
- Nephron Basics: Each kidney contains about a million nephrons. Each nephron consists of:
- Glomerulus: A network of tiny blood vessels where filtration begins.
- Tubules: Structures that reabsorb essential substances and secrete waste.
Blood Supply
- Renal Artery: Supplies blood to the kidneys.
- Renal Vein: Drains blood away from the kidneys.
Nerve Supply
- Autonomic Nervous System: Regulates kidney function and blood flow through sympathetic and parasympathetic fibers.
Types of Nephron Abscess
- Acute Abscess: Rapid onset, often due to bacterial infection.
- Chronic Abscess: Develops over time, may be linked to underlying conditions.
- Perinephric Abscess: Located around the kidney, affecting nearby tissues.
Causes
- Bacterial Infections: Most common cause; often E. coli.
