Scan Sonogram Kidney Stones
Would it be weird if I passed up a CT scan and requested a sonogram instead to check for kidney stones?
Not necessarily...: Ct is the most sensitive test to look for kidney stones. Very small stones or stones outside the kidney (i.e., in the ureters or pelvis) can be missed by ultrasound. If worried about radiation, there is a low dose protocol for ct that can be used to look for stones. The amount of radiation exposure for low dose ct is about the same as a plain x-ray. Ask the imaging center if they perform this. ...Read moreSee 2 more doctor answers
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
Urologist suggests CT scan after xray and sonogram suggest kidney stones, but he saw only "shadow." Is CT scan necessary to confirm stones? No pain.
CT scans are: more accurate than ultrasound for diagnosis of kidney stones and other anatomical abnormalities of kidneys such as tumors. If you are having painless hematuria, this condition raises suspicion of possible tumor in urinary tract. ...Read more
Hi dr! i want to ask.. is it possible that a kidney stones was seen in ultrasound but can't be seen in ct scan with contrast?

This is the question that i sent, the doctor has sent me for a kub ultrasound scan to check for kidney stones but do kidney stones have same symptoms?
It it possible for kidney stones to show up on ultrasound and not of CT scan if so what kind of stones would they be (uric acid)?
Some burning after urination & occasional flank pain 6+wks ago. Ultrasound revealed 5mm kidney stone. No urinary symptoms since. Considering radiation exposure is a CT scan necessary in your opinion?
No: If you are no longer having symptoms and your urinalysis is normal, then I think you already have the information you need. Sometimes a stone is not identified on an ultrasound, and persistent pain or blood in the urine needs to be investigated. Then a CT would be helpful. I am assuming that your ultrasound otherwise revealed normal kidneys, etc. ...Read moreSee 1 more doctor answer
After several tests with urologist for hermaturia (all neg) sonogram showed a small kidney stone. I am noticing blood after urine sometimes after bowel movements, is this the stone or something else?
IgA nephropathy: A small kidney stone is unlikely to cause recurrent hematuria. Several kidney diseases can cause blood in the urine. The source of bleeding and the significance of hematuria can be determined by microscopic examination of urine. Iga nephropathy is a disease which tends to causes similar symptoms. Please see a nephrologist. ...Read moreSee 1 more doctor answer
I was sent to get a blood test because of kidney stones that a sonogram revealed I have. My results show that my MPV is high at 12.7 Is that normal?
Platelets: MPV=mean platelet volume This is a little used value in thehemograom, with only weak correlation with disease states. Like red cells, younger platelets tend to be bigger, and stress reactions may prompt earlier release from the marrow. Many possible causes, but little utility in isolation. ...Read more
Why does my urologist think that a CT scan is more accurate for kidney stones when my pain and history match the ultrasound finding?
Your urologist: already answered you , although sonogram is less invasive , no radiation , inexpensive , when CT is done with contrast will show even small stone , status of ureter , where it is blocking, possible to predict if you will be able to pass the stone with out intervention . If you don't believe your doctor take a second opinion ...Read more
Urologist ordered CAT bc blood in urine and an earlier ultrasound that showed 4 kidney stones. What body parts will show up in the CAT scan?
Abdomen and pelvis: The CT scan ordered when a patient has blood in the urine is of the abdomen and pelvis. It will show the kidneys, ureters, bladder and will also incidentally show the liver, lower lobes of lungs and spleen. Normally contrast is given intravenously when checking on urinary bleeding. Best wishes. ...Read moreSee 1 more doctor answer
Seriously- renal stones are the result of postive and negatively charged particles in urine binding together and precipitating as solids- most frequently as calcium- oxalate. This happens most often when the urine is concentrated- ie when you are dehydrated. And trying to pass these stones from the kidney to the bladder is incredibly painful. ...Read more
The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more
