What can mimic kidney stone pain

Once your health care provider finds out why you are forming stones, he or she will give you tips on how to prevent them. This may include changing your diet and taking certain medications. There is no "one-size-fits-all" diet for preventing kidney stones. Everyone is different. Your diet may not be causing your stones to form. But there are dietary changes that you can make to stop stones from continuing to form.

Diet Changes

Drink enough fluids each day.

If you are not producing enough urine, your health care provider will recommend you drink at least 3 liters of liquid each day. This equals about 3 quarts (about ten 10-ounce glasses). This is a great way to lower your risk of forming new stones. Remember to drink more to replace fluids lost when you sweat from exercise or in hot weather. All fluids count toward your fluid intake. But it's best to drink mostly no-calorie or low-calorie drinks. This may mean limiting sugar-sweetened or alcoholic drinks.

Knowing how much you drink during the day can help you understand how much you need to drink to produce 2.5 liters of urine. Use a household measuring cup to measure how much liquid you drink for a day or two. Drink from bottles or cans with the fluid ounces listed on the label. Keep a log, and add up the ounces at the end of the day or 24-hour period. Use this total to be sure you are reaching your daily target urine amount of at least 85 ounces (2.5 liters) of urine daily.

Health care providers recommend people who form cystine stones drink more liquid than other stone formers. Usually 4 liters of liquid is advised to reduce cystine levels in your urine.

Reduce the amount of salt in your diet.

This tip is for people with high sodium intake and high urine calcium or cystine. Sodium can cause both urine calcium and cystine to be too high. Your health care provider may advise you to avoid foods that have a lot of salt. The Centers for Disease Control (CDC) and other health groups advise not eating more than 2,300 mg of salt per day. The following foods are high in salt and should be eaten in moderation:

• Cheese (all types)
• Most frozen foods and meats, including salty cured meats, deli meats (cold cuts), hot dogs, bratwurst and sausages
• Canned soups and vegetables
• Breads, bagels, rolls and baked goods
• Salty snacks, like chips and pretzels
• Bottled salad dressings and certain breakfast cereals
• Pickles and olives
• Casseroles, other "mixed" foods, pizza and lasagna
• Canned and bottled sauces
• Certain condiments, table salt and some spice blends

Eat the recommended amount of calcium.

If you take calcium supplements, make sure you aren't getting too much calcium. On the other hand make sure you aren't getting too little calcium either. Talk with your health care provider or dietitian about whether you need supplements. Good sources of calcium to choose from often are those low in salt. Eating calcium-rich foods or beverages with meals every day is a good habit. There are many non-dairy sources of calcium, such as calcium-fortified non-dairy milks. There are good choices, especially if you avoid dairy.

You can usually get enough calcium from your diet without supplements if you eat three-to-four servings of calcium-rich food. Many foods and beverages have calcium in them. Some foods and beverages that might be easy to include on a daily basis with meals are:

Eat plenty of fruits and vegetables.

Eating at least five servings of fruits and vegetables daily is recommended for all people who form kidney stones. Eating fruits and vegetables give you potassium, fiber, magnesium, antioxidants, phytate and citrate, all of which may help keep stones from forming.

A serving means one piece of fruit or one potato or one cup of raw vegetables. For cooked vegetables, a serving is ½ cup. If you are worried you may not be eating the right amount of fruits and vegetables, talk to your health care provider about what will be best for you.

Eat foods with low oxalate levels.

This recommendation is for patients with high urine oxalate. Eating calcium-rich foods (see table above) with meals can often control the oxalate level in your urine. Urinary oxalate is controlled because eating calcium lowers the oxalate level in your body. But if doing that does not control your urine oxalate, you may be asked to eat less of certain high-oxalate foods. Nearly all plant foods have oxalate, but a few foods contain a lot of it. These include spinach, rhubarb and almonds. It is usually not necessary to completely stop eating foods that contain oxalate. This needs to be determined individually and depends on why your oxalate levels are high in the first place.

Eat less meat.

If you make cystine or calcium oxalate stones and your urine uric acid is high, your health care provider may tell you to eat less animal protein.

If your health care provider thinks your diet is increasing your risk for stones, he or she will tell you to eat less meat, fish, seafood, poultry, pork, lamb, mutton and game meat than you eat now. This might mean eating these foods once or twice rather than two or three times a day, fewer times during the week, or eating smaller portions when you do eat them. The amount to limit depends on how much you eat now and how much your diet is affecting your uric acid levels.

Medications

Changing your diet and increasing fluids may not be enough to prevent stones from forming. Your health care provider may give you medications to take to help with this. The type of stone and the urine abnormalities you have will help your health care provider decide if you need medicine and which medicine is best. Common medications include:

Thiazide diuretics

are for patients who have calcium stones and high levels of calcium in their urine. Thiazides lower urine calcium by helping the kidney take calcium out of the urine and put it back in the blood stream. When taking thiazides, you need to limit how much salt you take in, as these medications work best when urine sodium is low.

Potassium citrate

is for patients with calcium stones and low urinary citrate, and for those with uric acid and cystine stones. Potassium citrate makes the urine less acidic or more alkaline (basic). This helps prevent cystine and uric acid stones. It also raises the citrate level in the urine, helping to prevent calcium stones.

Allopurinol

is frequently prescribed for gout, which is caused by high uric acid in the blood. Allopurinol not only lowers the level of uric acid in the blood but also in the urine, so it may also be prescribed to help prevent calcium and uric acid stones.

Acetohydroxamic acid (AHA)

is for patients who produce struvite or infection stones. These stones form because of repeated urinary tract infections (UTI). AHA makes the urine unfavorable for struvite stones to form. The best way to prevent stuvite stones is to prevent repeated UTIs caused by specific types of bacteria and to completely remove the stones with surgery.

Cystine-binding thiol drugs

are used only for patients who form cystine stones. These medications (d-penicillamine or tiopronin) bind to cystine in the urine and form a compound that is less likely than cystine to crystallize in the urine. This drug is used when other measures fail, such as raising fluid intake, reducing salt intake or using potassium citrate.

Vitamin supplements

should be used carefully as some can increase your risk of forming kidney stones. Your health care provider and a dietitian may be good sources of information about over-the-counter nutritional supplements.

Kidney stones and pain

Kidney stone pain can be excruciating. Individuals who have never had a stone may be suffering from a great deal of discomfort without knowing why. In reality, kidney stones are generally silent (asymptomatic) until they begin to pass. A stone that grows to 3 millimeters or larger can block the ureter as it moves from the kidney to the bladder. This movement can cause unbearable pain, usually in the lower back, right / left flank, or groin.  Kidney stone pain can be intermittent or ongoing.

Stone symptoms

Kidney stone pain is only one symptom that patients experience. Understanding other warning signs may help them avoid a great deal of suffering. This will also aid in securing a quick diagnosis and treatment. Below is a list of symptoms that kidney stone patients may experience. If you’re experiencing these symptoms, it’s important to seek immediate medical help.

1. Severe pain – Pain that prevents patients from finding a comfortable position, including severe pain in the lower back, abdomen or groin. If pain is not relieved by changing positions, it could be a kidney stone.  Depending on its size, the stone may be lodged somewhere between the kidney and bladder.  The pain can come in waves, be a stabbing pain or throbbing pain. Pain can last as little as 20 minutes or as long as an hour (or more).  If the pain does not abate, go to the emergency room.
2. Nausea and vomiting – If the pain is so severe that it is causes nausea and/or vomiting, the patient should go to an emergency room as soon as possible.  Oftentimes described as the worst pain of their lives, patients with kidney stones should not hesitate to seek treatment.
3. Fever and chills – Fever and chills most often happen when an infection is present.  Again, it is important to seek  immediate help to lower the chances of developing sepsis.
4. Blood in the urine – Visible blood in the urine (hematuria) is an indication that a stone has started to pass from the kidney to the bladder and has become lodged (likely in the ureter, a tube that connects the kidneys to the bladder).  Since the ureters are usually 3 to 4 mm in diameter, any stone larger than this can become stuck.  If not taken care of promptly, the stone can tear the ureter introducing blood into the urinary tract.
5. Difficult and painful urination – Blockage in the ureter can cause difficulty in passing urine.  If urine cannot pass, it can cause an infection.  The stone may also be in the urethra, the tube that passes urine from the bladder outside the body.
