Clinical diagnosis, imaging, x-ray, IVP and retrogade pyelogram are among the methods used for diagnosing kidney stones. However, a CT/ CAT (Computed Topography) scan is the most popular way. This is because it uses a combination of X-ray and computer graphics that produce images with elaborate cross-sectional areas along horizontal and vertical aspects of the body and also reduces exposure to radiation.

So, why should one choose a CT Scan for kidney stone diagnosis over the other methods? You will be delighted to know that this method of diagnosis does not require the use of intravenous contrast which might be risky to some patients. Secondly, it does not cause damage to any body parts. It also does not have any side effects and its diagnosis is accurate and perfect as all things are scanned throughout. However, it might fail to detect rare stones which are formed by strange chemical residues found in the urine.

Another advantage of a CT scan for kidney stone is that its very quick. The reason behind this is that it uses renal-colic study so as to immediately diagnose the flank pain that occurs due to kidney stones. The KUB of the abdominal region is done by taking a single standard x-ray if the results are positive. This helps doctors to determine the exact size or shape and one can just go for regular x-ray check-ups instead of this costly method.

However, there are special kind of people who cannot use the CT scan for kidney stones always. These are the pregnant women who can only do this after consulting their physicians. Though costly, this method ensures that you get the best value for your money as you only need this treatment only once. It also minimizes the amount of radiation exposure.
