8 Signs and Symptoms of Kidney Stones

What Are Kidney Stones?

Kidney stones (renal calculi) are clustered deposits of minerals and salts in your kidneys. When the urine gets concentrated, it leads to the crystallization of these salts and minerals, forming these stones. These stones can deposit anywhere in your urinary tract, from your kidneys to even your bladder. Kidney stones formation happens when the urine contains substances that often form crystals— such as uric acid, calcium, and oxalate — then the urine can dilute. Some medical conditions, obesity, excess weight, and not drinking enough water are other causes of kidney stones. These stones don’t cause any permanent damage if diagnosed and treated on time. But, passing these stones through your urethra is very painful. You may need nothing more than to drink lots of water and take pain killers to pass a kidney stone. But if the stone has become stuck in the urinary tract and is causing a urinary infection, you may have to go under surgery.
And if you are at risk of developing the stones again, you’ll have to take other preventive methods recommended by your doctor.

  • Calcium phosphate:Calcium phosphate also is a substance that forms the stones in the kidneys. These stones generally form because of metabolic conditions, as Tubular Acidosis. It may also be associated with certain medicines taken for seizures or migraines, such as topiramate (Topamax, Qudexy XR, Trokendi XR).
  • Struvite stones: Struvite stones are caused because of urinary tract infections. These stones can become quite large by multiplying and sometimes have few symptoms and warnings.
  • Uric acid stones: Certain genetic factors, a high protein diet, and losing too much fluid from the body can cause them to form. Uric acid stones can develop in people with diabetes or metabolic syndrome.
  • Cystine stones: A Hereditary disorder called cystinuria causes the kidneys to excrete a specific amino acid in too much quantity, causing stone formation.
