How often is it really safe to have a CT scan for kidney stones?

How often is it really safe to have a CT scan for kidney stones?

Not often: Having a ct scan exposes a person to low doses of radiation. Most people will have at least one ct scan in there lifetime, which is not harmful. However, people with chronic conditions, like stones, may be exposed to radiation from imaging tests like ct scans multiple times in their life, which can be harmful. Trying to use alternative methods like ultrasound, if possible, is a good option. ...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

Need expert opinions. How often is it safe to have a CT scan for kidney stones?

Only when needed: You should only have a ct scan when the benefit to you at that moment is greater than the risk from the radiation. Hard to measure, but, you should not get one "just to see where the stones are". You should try to always use techniques to limit radiation dose, dual energy ct can provide insight as to what kind of kidney stones there are to maximize treatment, and consider MRI (no radiation). ...Read more

Had l spine xray and CT scan for kidney stones, all clear. Low back pain..Would l spine xray have shown lower back tumor? No stones, uti, etc.

Had l spine xray and CT scan for kidney stones, all clear. Low back pain..Would l spine xray have shown lower back tumor? No stones, uti, etc.

No: An x-ray of the lumbar spine would predominantly show only bone. In general, an x-ray is not a very sensitive test to detect the specific cause of back pain in most patients. Consider requesting an MRI which shows the bone, but also shows the nerves, discs, and other soft tissues of the back and is therefore much more sensitive than an x-ray. ...Read more

The most common: Adrenal mass seen in about 15% of patients is an adrenal adenoma which is a benign tumor. It is easy to characterize on MRI because we can show there is fat in the tumor. This usually (94% accurate) means that the adrenal tumor is benign. But we make sure by following the tumor with additional MRI studies, which do not use harmful radiation. Ultrasound is not as accurate for followup. ...Read more

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

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

Im 20 years old and had a CT scan for kidney stone and it showed a incidental 11 mm interpolar left renal cortical cyst no pain should I be worried?

Renal Cysts: Renal cysts are benign fluid filled thin wall structures on the kidney that are commonly discovered when looking for something else on an imaging study. Rarely do they cause symptoms and if simple cysts are usually of no concern. ...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
