Which type of kidney stone is the most common?

Calcium stones are indeed the most common type of kidney stones, accounting for approximately 70-80% of all cases. These stones primarily form as calcium oxalate or calcium phosphate crystals in the urine. The saturation of calcium in the urine, low urinary volume, and elevated levels of oxalate or phosphate can contribute to the formation of these stones.

Various factors, including diet, hydration status, and certain metabolic disorders, can influence the risk of developing calcium stones. For example, a diet high in oxalate-rich foods, such as spinach or nuts, along with inadequate fluid intake, can increase calcium oxalate stone formation. Understanding the majority type of kidney stones is critical in both diagnosis and management, allowing healthcare providers to implement effective prevention strategies tailored to the individual patient.
