Renal Fibrous Capsule Stones

• Renal?: Related to the kidneys.
• Fibrous Capsule: The protective layer surrounding each kidney.
• Stones: Hard mineral deposits that form in the kidneys.

Pathophysiology

• Structure: The kidney has a fibrous capsule that protects it and helps maintain its shape.
• Blood Supply: The renal? arteries supply blood to the kidneys, while the renal veins drain it.
• Nerve Supply: The kidneys receive nerves from the sympathetic nervous system, helping regulate their function.

Types of Renal? Stones

1. Calcium Stones: Most common, formed from calcium oxalate or calcium phosphate.
2. Struvite Stones: Associated with urinary tract infections.
3. Uric Acid Stones: Result from high uric acid levels, often seen in people with gout.
4. Cystine Stones: Rare, caused by a genetic disorder leading to cystine in urine.
