Kidney Stones
A kidney stone is characterized by the presence of a small hard cluster of substances such as oxalate, ammonia, magnesium, uric acid, calcium, and uric acid. Since the fluid in your urine cannot dilute these substances, they will come together and crystallize to form kidney stones [5]. The size of the stones may vary. They can be as small as a grain of sand or as big as a grape. Stones can develop in any region of the urinary system. They can also lead to kidney or urinary tract infections. The crystalline materials also block the passage of fluids in the ureters. You may not experience pain if the kidney stones are dormant. However, they can become extremely painful as they pass from the kidney to the bladder.
