A cortical nephron hematoma is a collection of blood (hematoma) within the cortical (outer) region of the nephron, the functional unit of the kidney. This condition can disrupt normal kidney functions, leading to various health issues.
Pathophysiology
Structure
- Nephron: The basic structural and functional unit of the kidney responsible for filtering blood and forming urine.
- Cortex: The outer part of the kidney where most nephrons are located.
- Hematoma: A localized collection of blood outside blood vessels, usually due to injury or bleeding disorders.
Blood Supply
- The kidneys receive blood through the renal arteries, which branch into smaller arterioles supplying the nephrons.
- A hematoma can compress these blood vessels, reducing blood flow and affecting kidney function.
Nerve Supply
- The kidneys are innervated by the autonomic nervous system, which controls blood flow and filtration rates.
- Nerve irritation from a hematoma can cause pain and disrupt normal kidney signaling.
Types of Cortical Nephron Hematoma
- Traumatic Hematoma: Caused by physical injury to the kidney.
- Spontaneous Hematoma: Occurs without obvious injury, often due to underlying conditions.
- Iatrogenic Hematoma: Results from medical procedures like biopsies or surgeries.
- Chronic Hematoma: Develops over time due to prolonged bleeding or repeated injuries.
Causes
- Blunt Trauma: Such as car accidents or falls.
