The renal corticomedullary junction is the area where the outer layer of the kidney (cortex) meets the inner layer (medulla). Diseases affecting this junction can lead to serious health problems, impacting how the kidneys filter blood and maintain fluid balance. This article explores the pathophysiology, types, causes, symptoms, diagnostic tests, treatments, and prevention strategies for these diseases.
Pathophysiology
Structure
The kidney is divided into two main parts:
- Cortex: The outer layer, which contains the nephrons (the functional units of the kidney).
- Medulla: The inner layer, responsible for concentrating urine and regulating water balance.
Blood Supply
The renal artery supplies blood to the kidneys. Once filtered, blood leaves the kidneys through the renal vein. The corticomedullary junction is particularly rich in blood vessels, making it crucial for kidney function.
Nerve Supply
The kidneys receive nerve supply from the autonomic nervous system, which regulates blood flow and urine production.
