How Are Kidney Stones Diagnosed

Your healthcare provider will discuss your medical history and possibly order some tests. These tests include:

  • Imaging tests: An X-ray, CT scan and ultrasound will help your healthcare provider see the size, shape, location and number of your kidney stones. These tests help your provider decide what treatment you need.
  • Blood test: A blood test will reveal how well your kidneys are functioning, check for infection and look for biochemical problems that may lead to kidney stones.
  • Urine test: This test also looks for signs of infection and examines the levels of the substances that form kidney stones.

Can Kidney Stones Be Prevented

    Rather than having to undergo treatment, it is best to avoid kidney stones in the first place when possible. It can be especially helpful to drink more water since low fluid intake and dehydration are major risk factors for kidney stone formation.

    Depending on the cause of the kidney stones and an individual’s medical history, changes in the diet or medications are sometimes recommended to decrease the likelihood of developing further kidney stones. If one has passed a stone, it can be particularly helpful to have it analyzed in a laboratory to determine the precise type of stone so specific prevention measures can be considered.

    People who have a tendency to form calcium oxalate kidney stones may be advised to limit their consumption of foods high in oxalates, such as spinach, rhubarb, Swiss chard, beets, wheat germ, and peanuts. Also drinking lemon juice or lemonade may be helpful in preventing kidney stones.

    How Can I Prevent Kidney Stones

    There are several ways to decrease your risk of kidney stones, including:

    • Drink water. Drink at least six to eight 8-ounce glasses every day . Staying hydrated helps you urinate more often, which helps flush away the buildup of the substances that cause kidney stones. If you sweat a lot, be sure to drink even more.
    • Limit salt. Eat less sodium. You may want to connect with a dietician for help with planning what foods you eat.
    • Lose weight. If youre overweight, try to lose some pounds. Talk to your healthcare provider about an ideal weight.
    • Take prescriptions. Your healthcare provider may prescribe some medications that help prevent kidney stones. The type of medication may depend on the type of stones you get.

    Types Of Kidney Stones

    How can I be tested for kidney disease?

    There are four main types of stones:

  • Calcium oxalate: The most common type of kidney stone which is created when calcium combines with oxalate in the urine. Inadequate calcium and fluid intake, as well other conditions, may contribute to their formation.
  • Uric acid: This is another common type of kidney stone. Foods such as organ meats and shellfish have high concentrations of a natural chemical compound known as purines. High purine intake leads to a higher production of monosodium urate, which, under the right conditions, may form stones in the kidneys. The formation of these types of stones tends to run in families.
  • Struvite: These stones are less common and are caused by infections in the upper urinary tract.
  • Cystine: These stones are rare and tend to run in families. What are Cystine Stones?

    Identification Tests And Treatment

    Not all kidney stones are alike. Some are painful, some are not. Some are small, some are large. And one stone may have a different makeup over the other. To assess the type of kidney stone you have, your doctor may ask you to collect your stones as they pass to determine the type. This can be done through straining your urine. Collection of urine over a number of days can also aid your doctor in determining the characteristics of your urine to determine an overabundance or lack of certain minerals.

    Once your doctor identifies the type of kidney stone you are suffering from, its size, and other characteristics, a more solid treatment plan can be delivered. Some stones pass on their own and you might be sent home with some pain medication and instructions to increase your fluid intake while the stone passes.

    Medications: If you are suffering from kidney stones, your doctor may prescribe you a narcotic for pain and treatment for infection. Some commonly prescribed medications include diuretics, phosphorus solutions, sodium bicarbonate, sodium citrate, allopurinol.

    Lithotripsy: This treatment method using sound waves to break up large stones. Once the large stones are broken up, the smaller parts can more easily pass through the urinary tract. Lithotripsy treatment often requires low doses of anesthesia because it can be rather painful and cause bruising on surrounding organs.

    The Best Way To Demonstrate The Presence Of A Kidney Stone Is With A Form Of Ct Scan

    Why do kidney stones cause problems?

    While many people with stones are unaware that they have them until they are found incidentally on x-ray images or scans, most people are also aware of the potential pain that stones can cause when they move. Often it is the smaller stones that give the most pain. Other problems are damage to kidney function, an association with infection, and blood in the urine.

    The combination of infection and obstruction is a dangerous condition that needs emergency treatment and drainage in hospital, that day. Symptoms of this are pain in the side of the abdomen and fever. If you fear this may be happening to you, go straight to your local hospital emergency department – tell them about any stones you may have and explain your current symptoms.

    How are kidney stones treated?

    Once formed, stones cannot generally be dissolved away. If they are not causing any bother and are not likely to damage the kidney, they do not necessarily need treatment. They may either be monitored with occasional x-rays, or eventually completely left alone, if there has been no change after a period of time.

    It is rare to have to offer an urgent surgical procedure the same day that severe pain occurs from a stone. However, where immediate treatment is required , it nearly always involves either a nephrostomy or a ureteric stent – both equally effective at draining an obstructed kidney.

    Both Ct And Ultrasound Find Most Kidney Stones

    Whether you have an ultrasound or a CT scan first:

    • Does not affect the amount of pain you have or how quickly your pain will go away.
    • Does not change the risk of having serious side effects or complications from kidney stones.
    • Does not change the risk of having to go back to the emergency department or stay in the hospital.

    Having an ultrasound first may help you avoid being exposed to radiation from a CT scan.

    • If you have an ultrasound first, you may need a second imaging test, which may be a CT scan. But, most people who have an ultrasound first do not need a CT scan.

    Note: If you and the emergency doctor decide on a CT scan, ask if it is possible to get a low-dose CT scan. Low-dose CT works as well as normal-dose CT to check for kidney stones and exposes you to less radiation.

    Are There Any Foods Or Drinks That Help Treat Kidney Stones Are There Any Home Remedies

    Kidney Stone Diagnosis Blood Test

    There are three liquids rumored to help with kidney stones:

    • Cranberry juice. Although cranberry juice can help prevent urinary tract infections , it doesnt help with kidney stones.
    • Apple cider vinegar. Vinegar is acidic and it can sometimes create changes to your urine, which helps with kidney stones. But, this doesnt always help. Talk to your healthcare provider about the use of vinegar.
    • Lemon juice. Lemon juice is rich in citrate, which can help prevent kidney stones from forming. Citrates are found in several citrus fruits including lemons, limes, oranges and melons.
    • Coffee. Studies show that coffee may decrease your risk of developing kidney stones.

    Avoid soda and other drinks with added sugar or fructose corn syrup. They increase your risk.

    What Abnormalities Do You Find In My Blood Test

    Even if you consult an expert to know about your kidney condition, you should ask a doctor to seek a second opinion about your blood test. Kidney stones can be caused due to certain disorders in the body, such as diabetes and parathyroid disease. In these cases, the doctors focus more on treating these ailments than preventing further kidney stones. Therefore, you need to ask the doctors about the factors leading to kidney stones and its always advisable to consult the best doctor to get the right care and proper treatment.

    Diagnostic Tests For Kidney Stones

    Your doctor conducts an initial physical exam and may order several tests, including blood and urine tests and imaging exams, to determine whether you have kidney stones and to diagnose the particular type and location. If you have passed a stone or had one surgically treated, your doctor may analyze the stone to determine its type and suggest additional testing to find out if you have more.

    All of these tests may be scheduled on the same day as your doctors visit. Our radiologists and urologists can also review the results of scans youve had done at other medical facilities.

    When Urinalysis And Other Urine Tests Help In Kidney Stone Diagnosis

    In addition to imaging tests, doctors usually order urine tests to help determine what type of stone you may have and why you are developing stones. This information can help your doctor better advise you about how to prevent future kidney stones, says Naim Maalouf, MD, an associate professor of internal medicine at UT Southwestern Medical Center in Dallas. At least 31 percent of people diagnosed with kidney stones develop another one within 10 years.

    Kidney stones are made of minerals and other substances that can be found in the urine that can be identified with testing. Types of kidney stones include calcium stones , uric acid stones, struvite stones, and cystine stones.

    Notably, a urinalysis test and urine culture can also tell doctors whether you also have an infection, which is a potentially life-threatening complication in combination with a kidney stone, says Seth K. Bechis, MD, an assistant professor of urology at UC San Diego Health in California. If urine is trapped behind an obstructing stone in the ureter, urine can become infected. This scenario can cause an infection of the kidney tissue or spread to the bloodstream.

    Doctors may perform the following urine tests in kidney stone diagnosis:

    A urinalysis with microscopy can also help doctors find evidence of bleeding or infection, says Dr. Maalouf.

    From this urine sample, doctors can tell whether people are predisposed to stone formation. We call it a stone risk profile, says Maalouf.

    What Is A Creatinine Test

    Testing and Treatment for Kidney Disease

    A creatinine blood test measures creatinine levels in your blood to see if your kidneys are working well. High creatinine levels in blood indicate that kidneys are not filtering waste like they should.

    A creatinine urine test, or creatinine clearance test, measures creatinine in your urine. Both tests are sometimes used together to assess kidney health.

    Your healthcare provider may order creatinine tests if you have:

    • Diabetes
    • An illness that could affect a kidney

    How Is A Renal Panel Different From A Comprehensive Or Basic Metabolic Panel

    There is considerable overlap between the measurements on a renal panel, basic metabolic panel , and comprehensive metabolic panel .

    The BMP has 8 components, all of which are included in the CMP, which has a total of 14 measurements. The components of the BMP and CMP are more standardized than the renal panel, which can vary between laboratories.

    The BMP, CMP, and most renal panels include measurements of glucose, electrolytes, calcium, and the waste products creatinine and urea nitrogen. The CMP and many renal panels also include measurement of albumin.

    An important difference for the comprehensive metabolic panel is its inclusion of tests that help assess the condition of the liver. These are tests found on a typical liver panel test.

    Because it is not as standardized, a renal panel test may include measurements, such as phosphorus or the anion gap, that are not found on the BMP or CMP.
