Renal cortical labyrinth aminoaciduria refers to a condition where excess amino acids are found in the urine due to issues in the renal cortical labyrinth.
- Renal Cortex: The outer part of the kidney where blood filtration begins.
- Labyrinth: Refers to the intricate network of tubules within the renal cortex.
- Aminoaciduria: Presence of amino acids in the urine.
In simpler terms, it’s when the kidneys’ filtering system in the cortex part isn’t working properly, leading to too many amino acids being excreted in urine.
Pathophysiology
Understanding the pathophysiology helps explain how aminoaciduria occurs.
Structure
- Renal Cortical Labyrinth: Comprises various tubules like proximal and distal tubules responsible for reabsorbing nutrients, including amino acids, from the filtrate back into the blood.
Blood Supply
- Renal Arteries: Supply oxygen-rich blood to the kidneys.
- Glomeruli: Tiny blood vessels in the renal cortex where filtration begins.
Nerve Supply
- Autonomic Nervous System: Regulates blood flow and filtration rates in the kidneys.
When there’s damage or dysfunction in the renal cortical labyrinth, the kidneys fail to reabsorb amino acids effectively, leading to aminoaciduria.
Types of Aminoaciduria
Aminoaciduria can be classified based on the specific amino acids present or the underlying cause:
- Generalized Aminoaciduria: Excess of multiple amino acids.
- Selective Aminoaciduria: Excess of specific amino acids, such as:
- Cystinuria: High cystine levels.
- Hartnup Disease: High levels of neutral amino acids.
