• Radiology tests used for kidney stones:  xray, ultrasound, ct scan, ivp and ct urography topics:     symptoms and diagnosis types of stones dietary prevention xray/ ct scan/ ultrasound/ ivp surgical removal/ lithotripsy causes of stones genetic causes medical diseases infections metabolic syndrome and diabetes links   author information   home physicians have multiple ways to look at kidney stones.   the method often depends on the severity of the problem, the type of stone, and the presence or absence of symptoms.    xray:   standard xrays of the mid to lower abdomen will include the kidneys, ureter and bladder.   xrays work by passing low doses of radiation through the patient's body onto a photographic negative.   when xrays pass through soft body tissues, they hit the film and cause it to turn black (exposure).   when a calcium stone or bone (which is also made of calcium) is present the xray cannot pass through and no exposure occurs.   the stone(s) and bones will appear white.   this technique can only detect stones which contain calcium.   it will miss pure uric acid or indinavir stones.   xrays can be done quickly and cheaply and are a quick, inexpensive, and useful technique for monitoring growth of a kidney stone. Ultrasound (u/s):   ultrasound is performed by passing a probe over the kidneys, ureters, and bladder.   sound waves are emitted from the probe and are integrated into an image of the urinary system that can be seen on a television screen.   this test can detect both calcium and non-calcium types of stones.   it often is not a good test to find a stone that is suddenly passing from the kidney through the ureter on its way to the bladder.   this is the time when stones hurt the most and cause people to seek immediate emergency medical assistance. buy generic viagra generic viagra online cheap viagra viagra for sale viagra online buy viagra viagra for sale online classicmotocrossimages.com/mbs-online-order-viagra-tb/ cheap generic viagra http://nationalityinworldhistory.net/bsh-buy-viagra-on-the-internet-xd/   if the stone has been lodged in the ureter for some time, then it can detect obstruction.   in this situation the ureter is abnormally dilated.   it is used by some for routine monitoring of new stones or growth of old stones. It has the benefit of no radiation.    computerized tomography (ct or cat scan): this is one of the best methods to detect kidney stones, especially when someone comes to the emergency room with severe pain (colic) due to a passing stone.   it is more sensitive than ultrasound or xray.   it is performed by placing the patient in an xray tube that creates several images of the kidneys, ureter, and bladder.   it can detect both calcium and non-calcium stone.   although it may sometimes miss crixivan/indinavir stones.   it is more expensive than an xray and requires more radiation.   since.
