Kidney stones are hard crystalline mineral materials that form in the urinary tract or in the kidney. They vary in size, with some kidney stones growing as large as golf balls. Kidney stones may affect both males and females although they are twice more likely to affect men than women.
Medical experts believe that at least one in twenty people may develop kidney stones in their lifetime.
When the stones are located in the kidney, it is termed Nephrolithiasis but if the stone is in the urinary tract, the medical term for that is urolithasis. Kidney stones that occur in the ureter are medically referred to as ureterolithasis. Stones that occur in the kidney are however more common than others.
