X-linked Recessive Nephrolithiasis is a rare genetic disorder that affects kidney stone formation. It primarily affects males, as the gene responsible for this condition is located on the X chromosome.
Pathophysiology
Structure
- Kidneys: The kidneys filter waste from the blood and produce urine.
- Ureters: Tubes that carry urine from the kidneys to the bladder.
- Bladder: Stores urine until it’s expelled from the body.
Blood Supply
- The kidneys receive blood from the renal arteries, which branch off from the abdominal aorta. This blood is essential for filtering waste and maintaining fluid balance.
Nerve Supply
- The kidneys and urinary tract are innervated by the autonomic nervous system, which regulates involuntary bodily functions.
Types of X-linked Recessive Nephrolithiasis
- Classic Type: Most common, presenting with recurrent kidney stones.
- Variant Type: May have additional symptoms or milder presentations.
- Severe Type: Rare, with more serious complications affecting kidney function.
Causes
- Genetic Mutations: Defects in specific genes responsible for stone formation.
- Family History: Hereditary factors play a significant role.
- High Calcium Levels: Can increase the risk of stone formation.
- Dehydration: Insufficient fluid intake leads to concentrated urine.
- Dietary Factors: High oxalate or sodium intake can contribute.
- Obesity: Increases the likelihood of kidney stones.
- Medications: Certain drugs can lead to stone formation.
