ما يمكن توقعه
Prior to test
Leading up to the test:
- You will need to have kidney function tests.
- The day before the test, you may be asked to use laxatives and possibly enemasto clean out your gut. This is because stool in the intestines may make it harder to read the x-ray pictures.
- Do not eat or drink after midnight.
وصف الاختبار
An IV line will be inserted. This will provide the contrast dye and any medicine that you will need. For the next 30-60 minutes, you will lie on a table while x-rays are taken at regular intervals. You may be asked to hold your breath each time an x-ray is taken. The dye will highlight your urinary system on the x-ray. This will allow your doctor to see these body parts at work and detect problems. Before the last x-ray, you will empty your bladder in a bathroom.
بعد الاختبار
You will be able to resume your normal activities and diet. Be sure to follow your doctor’s instructions.
