Kidney stones are small, hard deposits made of minerals and salts that form in the kidneys. They can cause severe pain and other symptoms when they pass through the urinary tract.
Pathophysiology
- Structure:
- The kidneys are bean-shaped organs located on either side of the spine. They contain renal pyramids, which are cone-shaped tissues that help filter blood and produce urine.
- Stones can form in these pyramids when there’s an imbalance in the substances that make up urine.
- Blood Supply:
- The kidneys receive blood from the renal arteries, which branch off the abdominal aorta. The blood is filtered to remove waste and produce urine.
- Nerve Supply:
- The kidneys are innervated by the renal nerves, which regulate kidney function and blood flow.
Types of Kidney Stones
- Calcium Stones: Most common type, usually calcium oxalate or calcium phosphate.
- Struvite Stones: Formed in response to an infection in the urinary tract.
- Uric Acid Stones: Form when the urine is too acidic.
- Cystine Stones: Rare stones that occur in people with a genetic disorder that causes the kidneys to excrete too much cystine.
Causes of Kidney Stones
- Dehydration
- High protein diet
- Excessive salt intake
- Family history of stones
- Obesity
- Digestive diseases (e.g., Crohn’s disease)
- Hyperparathyroidism
- Certain medications (e.g., diuretics)
- Medical conditions (e.g., diabetes)
- Frequent urinary tract infections (UTIs)
- Low calcium intake
- High oxalate foods (e.g., spinach, nuts)
- Cystinuria (a genetic disorder)
- Gout
- Lack of physical activity
- High sugar intake
- Acidic urine

Diagnostic Tests
- Urinalysis: Tests urine for crystals, minerals, and other substances.
- Blood tests: Checks for high levels of calcium, uric acid, or other substances.
- CT scan: Provides detailed images of the kidneys and urinary tract.
- X-rays: Can detect some types of stones.
- Ultrasound: Uses sound waves to create images of the kidneys.
- IVP (Intravenous Pyelogram): A dye is injected to highlight the urinary tract.
- MRI: Used less frequently but can help in specific cases.
- Stone analysis: Examining stones that have passed to determine their type.
- 24-hour urine collection: Measures the amounts of minerals and fluids in urine.
- Cystoscopy: A thin tube is inserted to examine the bladder and urethra.
- Urography: Uses imaging to see the urinary system.
- Renal function tests: Assesses kidney performance.
- Electrolyte panel: Checks the levels of various minerals in the blood.
- Genetic tests: For inherited conditions like cystinuria.
- pH test: Measures the acidity of urine.
- Hydration tests: Assesses fluid intake and output.
- Dietary assessment: Evaluates dietary habits.
- Ultrasonography: Non-invasive imaging to detect stones.
- Biopsy: Rarely performed but can be used in complex cases.
- Endoscopic procedures: Visual inspection of the urinary tract.
