Kidney stones are actual stones that form in the kidneys. Salts, such as calcium, oxalate, sodium, magnesium, or uric acid, can create crystals in the kidney. Eventually these crystals become stones. Stones can cause pain, blood in the urine, or even block the kidney.
• Blood in the urine
Diagnosis is usually dependent on seeing a stone in the urinary tract. Your doctor may order an XRay, ultrasound, or CT scan to visualize the stone. Treatment of kidney stones depends on the size, location, and number of stones. If a stone gets stuck in the ureter, the tube that drains the kidney, you may need medicine or surgery to help pass it.
