Calyceal stones, or kidney stones, form in the calyces of the kidneys. These are small, hard deposits made of minerals and salts. They can be painful and may lead to serious health issues if not treated.
Pathophysiology
Structure
- Kidneys: Bean-shaped organs that filter blood and produce urine.
- Calyces: The cup-like structures in the kidneys where urine collects before it moves to the bladder.
- Ureters: Tubes that carry urine from the kidneys to the bladder.
Blood and Nerve Supply
- Blood Supply: The renal arteries supply blood to the kidneys, while renal veins carry blood away.
- Nerve Supply: The kidneys receive nerve signals from the autonomic nervous system, which controls involuntary actions.
Types of Calyceal Stones
- Calcium Stones: The most common type, formed from calcium oxalate or calcium phosphate.
- Struvite Stones: Form in response to urinary infections.
- Uric Acid Stones: Form when urine is too acidic.
- Cystine Stones: Rare stones that form in people with a genetic disorder that causes excessive cystine in urine.
Causes of Calyceal Stones
- Dehydration: Not drinking enough water.
- Diet: High intake of salt, sugar, and animal protein.
- Obesity: Being overweight can increase the risk.
- Medical Conditions: Conditions like diabetes and gout.
- Family History: Genetics can play a role.
- Certain Medications: Some drugs can increase stone risk.
