    What is a CT scan of the Kidneys (KUB) for Stones?

    ct scan kub kidney stonesCT scans are frequently used to evaluate the internal structures of the body. A variety of trends have increased the use of CT including new high resolution scanners that give greater anatomical detail and faster scanning time - scans that used to take minutes can now be done in seconds.

    A CT scan of the Kidneys for stones is a CT scan test that specifically looks for stones in the Kidneys, Ureters and Bladder (therefore KUB). This scan is frequently done in the emergency room for patients with sudden onset sharp side and back pain who have blood in their urine. It's also ordered by outpatient doctors as well for similar symptoms. As an outpatient you may get an order from your doctor for:

    "r/o renal stones" -  CT KUB is very good at picking up small and large calcified stones in the kidneys. It can also detect stones in the ureters which are small tubes that connect your kidneys (just under your rib cage) to your bladder (in the pelvis).

    "h/o hematuria"- hematuria means blood in the urine. Stones can irritate the urinary drainage system leading to mild bleeding. The bleeding is usually detected on a urine lab test ("microscopic hematuria") or occasionally can present with obvious, visible bleeding ("gross hematuria").

    "h/o flank pain" - renal stones occasionally cause dull or sharp pain along the sides of your lower chest and upper abdomen. Sometimes the pain can radiate to the pelvis and into the testicle or labia. This type of pain is can be seen with urinary medical issues.

    (FYI - "r/o" is short for "rule out" and "h/o" is short for "history of")

    An CT scan of the kidneys will evaluate:

    Kidneys, Ureters, Bladder

    A CT scan of the kidneys is designed to look for small (or large) stones that form in the kidneys and migrate into the ureters and bladder.

    Liver, Gallbladder, Pancreas, etc

    Since the CT scan includes nearby structures, many of the internal organs of the abdomen and pelvis will also be seen and can be evaluated. This includes the liver, gallbladder, pancreas, spleen, bowel loops, prostate, and uterus for example.

    Your CT scan for stones:

    Keep in mind that a CT scan for stones is actually two separate tests done together: a CT scan of the Abdomen and CT scan of the Pelvis. The test is usually done without IV dye contrast.

    A CT scan of the stones takes about 5 minutes or so to complete once you're on the table. If you are going for one, wear loose comfortable clothing. If you're insured, you may need to have your test authorized (approved) by your insurance company first.

    Question: I have had kidney stones in the past; however the pain started in the back area. This time around I have pain in the front just under my right ribcage. It's been in the same area for several months, not sever though. Could kidney stones be cause the pain in this area? Gallstones were not detected with an ultrasound. 
     
     
     
    Thanks, Mike

    Like Mike I have had a few kidney stones in my 42 years. I have withing the last month passed a 3mm stone and a smaller one and as I have stopped "looking" (using jars to check for stones, I may or may not have passed the 3rd small stone that came up on the ct kub. 
     
     
     
    The pain under the ribs is a new and disturbing thing for me as well. The back pain is pretty mild and manageable, but this abdominal pain just below ribs can be very severe eating seems to help a little but I usually use hydrocodone to help kill it. Wouldn't other problems (gall, liver etc) show up on ct. What else could cause this pain?

    Hi Kyle, 
     
    Kidney stones and gallstones can both cause the type of pain you and Mike have described. But if the pain is different you should probably have your doc check you over.

    I’m always getting bladder infection, at least 6 times a year over the last 10 years…this month I’ve had my 3rd bladder infection, my doctor told me that the antibiotics he gave me didn’t work for me so he changed my antibiotic for me, I felt better right after I started taking it, but 2 days after I finished the packet I started feel sick again my doctor then put me back on the same antibiotics this was my 3rd packet of antibiotics Is just not working I’m still very sick…  
    I had an x-ray, ultrasound for upper and lower abdomen and blood & urine test done… my CRP levels were at 150 and I had UIT and high level of blood in my urine. 
    Mt symptoms > abdomen pain, vomiting, fever, blood in urine, lower back pain and fainting… should I change my doctor? Please help me
