Kidney Stone Treatment: Symptoms, Causes, Diagnosis, Treatment & Prevention

 

Kidney stones are one of the most common urinary tract problems affecting millions of people worldwide. These hard mineral deposits form inside the kidneys and can cause severe pain when they move through the urinary tract. While small kidney stones may pass naturally, larger stones often require medical treatment.

Understanding the symptoms, causes, treatment options, and preventive measures can help protect your kidney health and reduce the risk of future stones.

What Are Kidney Stones?

Kidney stones (renal calculi) are hard deposits made of minerals and salts that form inside the kidneys. They develop when urine becomes concentrated, allowing minerals such as calcium, oxalate, and uric acid to crystallize and stick together.

Kidney stones can vary in size—from tiny grains of sand to stones several centimeters wide.

Types of Kidney Stones

The most common type, usually made of calcium oxalate or calcium phosphate.

2. Uric Acid Stones

Often develop in people who eat a high-protein diet or have gout.

3. Struvite Stones

Usually caused by urinary tract infections (UTIs).

4. Cystine Stones

A rare type caused by an inherited genetic disorder.
