A Word About Minimizing Radiation Exposure
Doctors take special care during x-ray exams to use the lowest radiation dose possible while producing the best images for evaluation. National and international radiology protection organizations continually review and update the technique standards radiology professionals use.
Modern x-ray systems minimize stray radiation by using controlled x-ray beams and dose control methods. This ensures that the areas of your body not being imaged receive minimal radiation exposure.
Imaging Tests That Help Doctors Diagnose Kidney Stones
Doctors typically diagnose kidney stones based on a physical exam, signs and symptoms youre experiencing , and imaging tests. Imaging tests that examine the kidneys, the bladder, and the ureters help doctors identify stones, says Sean Hashmi, MD, a nephrologist at Kaiser Permanente in Southern California.
The most common imaging tests used for diagnosing kidney stones are:
- Computerized Tomography Scan This imaging test creates three-dimensional images of the abdomen and pelvis, does not require a contrast dye, and can be performed with a low dose of radiation, says Dr. Hashmi. ER doctors often order a CT scan for a suspected kidney stone because the test helps them make a quick and accurate diagnosis.
- Ultrasound An ultrasound uses sound waves to create real-time images of the body. Doctors may use this test to diagnose kidney stones in pregnant women and other people who want to avoid radiation. One drawback of using ultrasound in the ER is that it may only be moderately accurate for diagnosing kidney stones, according to a review study published in February 2018 in The Journal of Emergency Medicine. 30877-6/fulltext” rel=”nofollow”> 7) Ultrasound can miss small stones in the kidney or stones in the ureter.

You may also be given medicine to help stop your nausea and vomiting. If you are dehydrated from vomiting, you may be given liquids through an IV tube.
Next, the emergency doctor will talk with you about your symptoms and medical history. If the emergency doctor thinks you might have a kidney stone, several tests may be done.
These may include:
- Urine Tests: To check for blood or mineral crystals in your urine or for signs of infection.
- Blood Tests: To check the health of your kidneys and for signs of a kidney or blood infection.

Imaging Tests To Check For Kidney Stones
Two imaging tests to check for kidney stones are a CT scan and an ultrasound. If the first imaging test is not clear, you may need a second test.
In the past, a CT scan was often used as the first imaging test to check for kidney stones. But, because a CT scan exposes people to radiation, the emergency doctor may suggest an ultrasound instead as the first imaging test.
|What is it?||A CT scan uses x-rays and computers to create three dimensional pictures of your urinary tract .||An ultrasound uses sound waves to create a picture of your kidneys and bladder. It is like the ultrasound used to look at the baby in the womb of a pregnant woman.|
|How is it done?||You lie still on a table that slides into a tunnel-shaped machine. A CT scan does not hurt.||You lie on your back or side, and a health care professional moves a small device around on your belly. An ultrasound does not hurt.|
|Does it expose you to radiation?||Yes, a CT scan exposes you to radiation. Radiation raises the risk of getting cancer.||No, an ultrasound does not expose you to radiation.|
What Are Kidney And Bladder Stones
Kidney or bladder stones are solid build-ups of crystals made from minerals and proteins found in urine. Bladder diverticulum, enlarged prostate, neurogenic bladder and urinary tract infection can cause an individual to have a greater chance of developing bladder stones.
If bladder stones are small enough, they can pass on their own with no noticeable symptoms. However, once they become larger, bladder stones can cause frequent urges to urinate, painful or difficult urination and hematuria.

Imaging Tests For Detecting Kidney Stones
Your doctor can diagnose kidney stones by examining your blood and urine. A blood test can show your doctor if theres too much uric acid or calcium in your blood. A urine test lets your doctor see the level of minerals in your urine. It also shows a lack of certain substances in your urine to prevent kidney stones from forming. Both tests will tell your doctor if you have an infection.
Your doctor may also suggest an imaging test to confirm the presence of kidney stones. Here are common scans used to test and diagnose 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.

Prevention Of Future Stones
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.
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 . 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 of urine daily.
Reduce the amount of salt in your diet.
Eat the recommended amount of calcium.
Renal Ultrasound And Ureteral Stones
A counter-argument for using ultrasound in diagnosing of kidney stones is that ureteral stones are usually difficult to visualize with ultrasound and unless they are located at UPJ or in the distal ureter will not be seen with ultrasound. This is correct but practically this does not make a difference. There is 3 possibilities:
1. Patient has hydronephrosis and the stone is not visible on ultrasound. In this situation the most likely explanation is a ureteral stone.
There are 3 possibilities:
that the stone is in the ureter or that it has passed. If the stone has passed the patients pain will resolve spontaneously over the next 24-48 hours. A repeat ultrasound in a few weeks documenting resolution of hydronephrosis is all that is needed.
If the stone was in the ureter, a KUB can be at obtained with minimal radiation exposure. A large stone greater than 7-9 mm will most likely be visible on KUB. Smaller stones that are also more likely to pass will not be visible on KUB. If the patient is comfortable, has no fever and has normal renal function, an optimal approach is for patient to try to pass the stone. The exact location of the stone does not matter all that much as long as the patient is willing to try to pass the stone.

How Does The Procedure Work
X-rays are a form of radiation like light or radio waves. X-rays pass through most objects, including the body. The technologist carefully aims the x-ray beam at the area of interest. The machine produces a small burst of radiation that passes through your body. The radiation records an image on photographic film or a special detector.
Different parts of the body absorb the x-rays in varying degrees. Dense bone absorbs much of the radiation while soft tissue allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray, and air appears black.
Most x-ray images are electronically stored digital files. Your doctor can easily access these stored images to diagnose and manage your condition.
How Does The Urinary System Work
The body takes nutrients from food and converts them to energy. Afterthe body has taken the food components that it needs, waste productsare left behind in the bowel and in the blood.
The urinary system helps the body to eliminate liquid waste in theblood called urea, and keeps chemicals, such as potassium and sodium,and water in balance. Urea is produced when foods containing protein,such as meat, poultry, and certain vegetables, are broken down in thebody. Urea is carried in the bloodstream to the kidneys, where it isremoved along with water and other wastes in the form of urine.

Can Kidney Stones Come Back
After the kidney stone has passed or after it is removed, another stone may form. People who have had a kidney stone in the past are more likely to get another stone in the future.
If you have had a kidney stone, talk with your health care professional about your risk of getting another one. Ask your health care professional what steps you can take to lower your risk of getting another kidney stone.
Kidney Stones : : Blood In Urine
It all started a little over a week ago, when I discovered blood in my urine late in the evening, thought nothing of it until i carried on peeing blood for the whole of the following day, day 3 was the day when I started getting extremely excruciating pains in my left side which caused me to roll around on the floor in agony and that pain would come and go in little or loads of pain, so I went to the doctors and he said kidney stones and gave me dicloflex and to drink lots of water to hopefully pass them, I also have a ct scan In a week but the pain in my sides has stopped, like it’s barely noticeable now, and because I’ve been drinking so much water the blood has stopped too, but I bet there are still blood cells in the urine not visible to the human eye? If I stop drinking water will the blood return? Basically will the ct scan come up with anything or will it find anything else? As the pain and blood has apparently stopped for the past two days, also I am certain I haven’t passed anything, I’ve kept a close eye and seen or felt nothing, I’ve had the odd bottle of lemonade because that ‘apparently’ helps, maybe it’s dissolved the stones?Thanks for your time
