    What does an ultrasound of the kidneys and bladder show?

    Posted by Ravi Sohal on Wed, Oct 21, 2009

    kidney bladder ultrasoundUltrasound tests use sound waves to create images of the internal organs. Kidney and bladder ultrasounds are frequently ordered to evaluate the organs of the genitourinary system which include the kidney, ureters, and bladder.

    Your doctor's order may read "r/o kidney stones", "hematuria" (blood in urine) or "renal disease", "flank pain" for example.

    (FYI "r/o" stands for rule out)

    Below are some common indications for an kidney and bladder ultrasounds.

    • Look for kidney infection (pyelonephritis) or injury.
    • Look for kidney tumors such as renal cell cancer, angiomyolipoma.
    • Evaluate the  kidney for disease and failure.
    • Evaluate the kidney for stones that can cause flank (side) pain or blood in the urine.
    • Look for ureteral blockages from stones, tumors or scarring.
    • Look for an bladder stones, tumors, or infection that can cause pain and blood in the urine.

    Kidney ultrasounds are also used to help kidney specialists (nephrologists) guide biopsy needles when tissue is needed for a definitive diagnosis in renal failure. They are also used to look for bladder urine retention.

    Below is a brief outline of the procedure.

    1. You will be asked to drink water to fill up your bladder.
    2. After you sign in, you'll be taken to the ultrasound room.
    3. An ultrasound technician will perform the test.
    4. Once you enter the room, you will lie down on a bed/gurney.
    5. The technologist will ask you to lift up your clothing, exposing your stomach and mid back area.
    6. He or she will place a a warmed gel solution over the skin.
    7. The technologist will use an ultrasound probe and glide it over your flanks and upper pelvis while taking pictures.
    8. You may be asked to sit up for a part of the test to get better pictures of the kidneys.
    9. You may also be asked to void your bladder and then return back to the ultrasound room for "post-void" images.
    10. The technologist may ask the Radiologist doctor to review the scan before you leave.
    11. An official report is generated by the Radiologist in about 24-48 hours.

    If you are insured kidney and bladder ultrasounds are covered. However, for uninsured patients these tests can be quite expensive. These tests can cost anywhere between $200 and $500.

    My dr. ordered an MRI of my kidneys? I have hypertension, so what is the purpose of the MRI?

    High blood pressure can be caused by narrowing of the blood vessels to your kidneys. Essentially, the kidneys are not getting enough blood so release hormones into the bloodstream to help increase flow causing high blood pressure.

    I just had a KUB u/s and was suprized at how quick it was. He made me sit up for it and scanned my back mostly and then I turned over and he just scanned around the pelvic region. 
    I'm worried as blood tests have indicated a possible kidney problem and I have pain on one side but... when he scanned the opposite side to the pain, he took ages, lots of beeps on his computer thingy and he pushed down really hard. On the left side (Which hurts) he didn't push at all and just glided the thing over it.  
    He made no comment about any of it, didn't even say it all looks fine. I guess they're not allowed to. Just said my doc would get a report. 
    I'm really worried because I can't imagine he could have seen much in the time he took to do it! Also, I'm surprised he didn't really look much on my tummy, mostly on my back. Now left really worried about what it all means! Surely they'd indicate in some way if there was important information or call a doctor to come and look at it? I have no idea what they normally do if they DO find something? 
    Anyone know please? Thank you..

    I had an ultrasound done recently and thought the radiologist/technician didn't know too much about my condition (neurogenic bladder), I have MS & have to catherize 3-4 x daily. This is why the dr. wanted the test done. I don't know the results yet but this left me with tenderness with my right kidney. Will this get better?

    I am scheduled for ultra sound test after tomorrow for my kidneys and ereters and the bladder. 
    My urine test read 292 for protein level, normal is 30 and danger zone is 300. no symptoms of blood in the urine, no pain when urinating, but some rt flank pain occasionally. OAB was my diagnosis by the urologist for excessive urination at night. What all these figures and tests are for and what they reveal if any?

    As a patient you may have to "tie" your doctor to a chair, but you have the right to ask him for more information. If he/she thinks you don't want more info,or your eyes glaze over, they won't take more of their time to tell you. DON"T BE AFRAID TO ASK, IT"?S YOUR LIFE,, get interested!

    I have had to take my daughter for ultrasounds every 6 months since she was 3 (she is now 11) because she has scarring in one of her kidneys. I guess they check to make sure the scarring isn't getting worse and this was all because she had 1 bladder infection when she was 3. She has never complained and is now a pro at it...LOL We had to go together today because my doc now ordered them for me. It didn't bother me at all one on side but on the other side I was in pain. I was supposed to see the doc next week with the results but 2 hours after we left from having the ultrasounds the office called me and wants me to come in tomorrow. That does not sound good to me and definitely wasn't expecting that. The ultrasounds are a piece of cake compared to having to go in and have him put the catheter camera up there.

    had an ultrasound done on my kidneys, theres a spot on one of them. I now have to have a CT scan. 
    Does a spot always mean trouble?

    Hi, I have read all comments and can sympathize. I am a 53 y.o. woman presented to emergency last Saturday with acute left side pain in kidney area, mainly in back. They found some blood in urine, did ct scan to rule out stone and diverculitis, which was negative. I also had headache and nausea. Blood test and urine test came back clear of infection. Still ill I went to my GP and then had an ultrasound. It came back clear. Today I went back to GP still very unwell. She suggested referred pain from spinal pain I suffer due to failed back surgeries, but, I whinged that it did not feel like being punched in back, and that at night when bursting to urinate, sometimes I could not and had to turn tap on. This hurt my kidneys because I was pushing. I also had dirrahea on the day of emergency, but, the extra pain killers has stopped that but bowel movements do hurt the kidneys again due to pushing. Anyway I would not accept her diagnosis of referred pain, so she did another urine test and found a massive infection. I now wonder do I have just a u.t.i. or a kidney infection? My right kidney is also starting to niggle. I have been put on amoxycillin 875mg. Very unhappy because I have been feeling so unwell for a week causing me not to study, and if I had not of insisted it was not referred pain, what could have happened? That is sepsis? Why did the hospital miss an infection in the urine? By the way do have a history of lower small calculi, and lots of u.t.i.'s. Also since diagnosis was uncertain, why did the hospital not admit me? The pain never went anywhere else but left kidney!

    I recently had an ultrasound of my kidneys and it came up with red spots on my kidneys  
    What does this mean?

    well, ultrasound reports are good in detecting stones ,swelling, differentiation.... and other abnormalities and its free of all those bad rays that other body imagings expose you to, as it uses sounds wave to develop images of you organs.
