Urinary tract stones are one of the most common urologic diseases and are more common in men than in women. There are many factors affecting the formation of urinary tract stones. The supersaturation of salts in the urine to form stone crystals, the insufficient amount of substances in the urine to inhibit the formation of crystals, and the presence of nuclear matrix are the main factors in the formation of stones. The size of urinary stones varies greatly, from as large as an egg yolk to as small as fine sand.
