You have been scheduled for a Potassium Sensitivity Test, or PST, (KCI Test) on ______________________at______________________.
It is possible that the symptoms you are experiencing may be caused by a problem that exists in the lining of your bladder. This test helps to confirm whether or not this is the case.
After urinating, a very small catheter (The approximate size of a strand of angel hair pasta) will be placed in your bladder. Two different solutions, approximately one ounce each, will be placed through the catheter into your bladder. You will be asked questions about how each solution makes you feel. The solutions will then be drained out through the catheter.
Approximately 15 to 20 minutes.
In most instances, the office nurse performs the test. In some cases, the physician chooses to perform the test.
You will be asked to remove all clothing from below the waist.
There may be slight discomfort as the catheter is inserted. In addition, there may be some discomfort and /or a feeling of urgency as one or both of the solutions are placed in your bladder. If this is the case, the testing will be considered complete, and the clinician will stop the test, instill a soothing solution into your bladder, and remove the catheter.
Please do not drink a lot of liquids prior to the test, and avoid talking any pain medications or medications that are used to reduce bladder spasms (Pyridium).
