Is It My Back or a Kidney Stone

Kidney stones

Over half a million people go to emergency rooms for kidney stone problems every year.

A kidney stone is a hard object that is made from chemicals in the urine. After formation, the stone may stay in the kidney or travel down the urinary tract into the ureter. Stones that don't move may cause a back-up of urine, which causes pain.

Symptoms & signs

  • severe pain on either side of your lower back
  • more vague pain or stomach ache that doesn't go away
  • blood in the urine
  • nausea or vomiting
  • fever and chills
  • urine that smells bad or looks cloudy

Causes & stone types

Calcium oxalate
Common, created when calcium combines with oxalate in the urine.

Uric acid
Common, caused by high purine intake leading to monosodium urate production.

Struvite
Less common, caused by infections in the upper urinary tract.

Cystine
Rare and tend to run in families with a history of cystinuria.

Risk Factors

The lifetime risk of kidney stones is about 19% in men and 9% in women

Family or personal history of kidney stones: If you or a family member has had kidney stones, you are more likely to develop a stone.

Dehydration: Excessive sweating or not drinking enough water can increase your risk for kidney stones.

Diets high in protein, salt, or sugar:Diets high in one or more of these items increases your risk for certain types of stones.

Obesity: Obesity has been linked to an increased risk of kidney stones.

Digestive diseases or surgeries: Surgeries which change your digestive system can affect absorption of calcium and water, increasing the concentration of stone-forming substances in your urine.

Other medical conditions: Conditions such as high blood pressure, diabetes, and cystinuria may increase the risk for kidney stones.

Diagnosis

Diagnosis of a kidney stone starts with a medical history, physical examination, and imaging tests.

Imaging tests: Your doctors will want to know the exact shape and size of the stone. This can be done with a high resolution CT scan. Other imaging options may include a KUB x-ray, or an intravenous pyelogram.

Urine testing: The doctor may also ask that you collect your urine for 24 hours to test for levels of stone-forming minerals and stone-preventing substances.

Blood testing: Your doctor will test your blood for calcium, phosphorus and uric acid.

Stone analysis: The stone will be analyzed after it comes out of your body in order to determine cause and a plan for prevention.

Treatment

Drink plenty of water

You should drink 2-3 quarts of liquid or 8-12 cups per day.

Be aware of sweat

Sweating leads to less urine production, allowing for minerals to settle. Keep well hydrated.

Cut back sodium

Work to cut back sodium in your diet.

Calcium oxalate

To reduce calcium oxalate stones, eat calcium and oxalate-rich foods in the same meal for them to have a higher likelihood to bind to one another in the stomach and intestines before the kidneys begin processing.

Uric acid

To reduce uric acid stones, cut down on high-purine foods such as red meat, organ meats, and shellfish.

Struvite

Ask your doctor about strategies to reduce your chance for struvite stones.
