If I already know I have a kidney stone is it necessary to have a CT scan?

If I already know I have a kidney stone is it necessary to have a CT scan?

Possibly: If you know you have a kidney stone, a ct scan is not necessary unless symptoms develop. If the person remians asymptomatic, periodic imaging with ultrasound or other x-rays are adequate. However, small stones may be missed on these studies and a ct scan may be required to locate the stone. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

How can a CT scan tell if you have a kidney stone or cancer or something else?

How can a CT scan tell if you have a kidney stone or cancer or something else?

It shows the kidney: The ct scan that is typically done to look for kidney stones is done without any intravenous contrast. Almost all stones show up easily on ct scan. Renal masses typically show on a non-contrasted ct but they may not be able to tell if it is a cancer or not. The ct also shows other organs in the abdomen and a mass or cancer may be visible on the study. ...Read more

I have a CT scan with a 3mm kidney stone, unobstructive causing considerable pain for over 3 weeks and have not seen a urologist. What should I do?

I have a CT scan with a 3mm kidney stone, unobstructive causing considerable pain for over 3 weeks and have not seen a urologist. What should I do?

Stones: A few pertinent facts about kidney stones: 1. Stones 5mm or less have a 66 to 85% chance of spontaneous passage. 2. Non-obstructing calculi do not cause pain. 3. Stones can move in and out of obstructing positions. 4. A urologist can be helpful even if the stone is likely to pass spontaneously, by appropriately medicating pain and prescribing a medication that may help some stones to pass. ...Read more

A : A 2mm stone will generally pass without the need for intervention but it may also have grown in size over 2 months and now may not pass, or you could have developed new ones. You should see your doctor and get a repeat ct scan to reevaluate the size and location. If you can't get to your doctor, and you are in pain go to the emergency department. ...Read more

How do I know if i've passed a kidney stone without another CT scan?

How do I know if i've passed a kidney stone without another CT scan?

Capture it: Hopefully, you were screening your urine and caught the stone. If the scan showed a 3 mm stone and you captured a 3mm stone, that is good enough. You should be pain free and a check of your urine from your doctor should show that the blood has cleared. ...Read more

Could a gall stone be mistaken for a kidney stone on a CT scan.?

No.: Ct scans precisely define the anatomy of different organs in the abdominal cavity. I can safely state that it would be impossible to confuse a gallstone from a kidney stone on a ct scan. ...Read more

On a CT scan is it easy to tell a 10mm kidney stone from a tumor. Could they be mistaken?

On a CT scan is it easy to tell a 10mm kidney stone from a tumor. Could they be mistaken?

Not usually: Bobcat: a kidney stone shows up on the ct scan as a bright white spot and the density is measured to insure that it is a calcium deposit/stone. A mass/tumor can have calcifications in it, but the mass would typically be seen and not just the calcium. It may also matter whether you ct was done with and without contrast injection to be sure the stone is not obstructing the urinary tract. ...Read more

I had a CT scan done for a kidney stone. It says there appears to be interval thinning of left cortex at the poles. What does that mean?

I had a CT scan done for a kidney stone. It says there appears to be interval thinning of left cortex at the poles. What does that mean?

Renal scarring: The upper and lower poles of the kidney or more vulnerable to scarring secondary to reflux. This may have occurred earlier in life secondary to a febrile urinary track infection characteristic for pyelonephritis which during the healing process can lead to scarring. You cannot eliminate scarring once present but you can help to prevent further urinary tract infections specifically with fever. ...Read more

After 2 wks, docs say kidney stone passed since ct scan showed up clear. 3 days later still having pain (not as excruciating but constant). Is normal?

See rmark: If the CT showed NO STONE the discomfort/pain may be resultant of stone passing,as it "scratches the lining of the ureter.Drink enough fluids.I advise you drink a glass of lemonade in AM and one glass in PM. I don't know the nature of your stone,but lemonade which contains CITRIC ACID does help prevent future ones.......Best of luck young lady ..JBR ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more


Kidney (Definition)

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
