What are the tests to be done ?
A through physical examination is very important to
understand the site and nature of the pain. It would also give
the doctor an idea as to whether the pain is likely due to a
stone within the urinary system or due to other reason.
A routine blood test and a urine test has to be done. The urine test will he helpful to know if there is blood in the urine, or if infection is present. It would be surprising to know that the doctor can make out if you are drinking adequate amount of fluids from the urine examination itself.
A special urine test in the form of urine culture has to be done to look for the presence of urinary tract infection . If it is present, it has to be treated with suitable anti-biotics for a specified time.
A blood test to measure the functioning of your kidney has to be done to know how your kidney is affected because of the urinary stone. Other metabolic tests may have to be done to look for any defects in your body which may be responsible for stone formation.This is very important as it is not only sufficient to treat for the stone but to find out why you formed the stone. So an appropriate treatment can be given so that you don’t form a stone again.
An ultra-sound examination is the first choice and it is
very useful. It does not involve any intervention and is very
safe. Even very small stones which cannot be seen on the X-Ray
can be seen on an ultrasound. The presence of any abnormality
in other organs in the abdomen can also be made out.
A X-Ray film is usually needed. It should be taken after proper bowel preparation. You may be asked to take some medicines which help in the easy passage of stools so that proper information can be obtained.
Depending upon the X-Ray and the ultra-sound findings a I.V.P. test has to be done. It is a special X- Ray test and involves the injection of a contrast agent intra-venously and taking a series of X-Ray films. Some people might be allergic to this contrast if this the case, then this test cannot be done. This is a very useful test which gives a lot of information about the kidneys ,ureter and bladder. Since this test involves the use of X-Ray which are damaging to the fetus, you have to inform your doctor if you have missed your periods or if you are pregnant.
A CT scan may have to done in some cases. It is now being increasingly used by the doctors. It is done quickly and the cost is also comparatively less.If adequate information cannot be obtained from the above mentioned tests, then additional interventional radiological tests may have to be done.
