Nephron stricture refers to a narrowing of the nephron, the functional unit of the kidney, which can hinder its ability to filter blood and produce urine. This condition can lead to kidney dysfunction and other serious health issues.

Pathophysiology

Structure

  • Nephrons: Each kidney contains about a million nephrons, each composed of:
    • Glomerulus: A network of tiny blood vessels that filter blood.
    • Tubules: Structures that reabsorb water and essential nutrients while excreting waste.

Blood Supply

  • Renal Arteries: Supply blood to the kidneys.
  • Renal Veins: Drain filtered blood away from the kidneys.

Nerve Supply

  • Autonomic Nervous System: Regulates kidney function, including blood flow and urine production.

Types of Nephron Stricture

  1. Congenital Stricture: Present at birth.
  2. Acquired Stricture: Develops due to factors like injury or disease.

Causes of Nephron Stricture

  1. Congenital Abnormalities: Genetic issues leading to structural problems.
  2. Inflammation: Chronic conditions like glomerulonephritis.
  3. Infections: Such as pyelonephritis.
  4. Trauma: Injuries to the kidney area.
  5. Kidney Stones: Can block urine flow.
  6. Tumors: Growths that can compress the nephron.
  7. Diabetes: Can damage blood vessels in the kidneys.
  8. High Blood Pressure: Causes strain on kidney structures.
