Re: NEED ADVICE - best test for kidney stones
First, if you think you have kidney stones, you should be straining your urine. In other words, all urine should flow through a strainer since that way, if you pass a stone, you would be able to save it and it could be analyzed as to its composition. Second, I just Googled the subject of diagnostics for kidney stones, and Cornell Urology says that a plain abdominal x-ray (KUB: kidneys, ureters, and bladder) is the first thing to be done - that 90% of the stones will be identified on it. X-rays are way cheaper than MRIs or CT scans!! A noncontrast spiral CT scan is also good to identify kidney stones (but costs more than just x-rays though possibly less than MRI). Ultrasound could also be used and is cheaper, but doesn't show the ureters very well. Find out the costs of the different tests before you sign up for them! Basically, x-rays and sonograms are cheaper and may be enough for you.
