Xray, also known as radiography, uses small doses of ionizing radiation to produce diagnostic images of the body. There is no specific prep for a KUB (kidneys, ureters, bladder) xray. You will lie down on the xray table and remain still for a few minutes while the xray is taken. You will be asked to remove any metallic objects that would be in the xray field, ex., belts, zippers, suspenders and any piercings.
There is no pain associated with xrays. You may be asked to lay in an uncomfortable position, but it will only be briefly.
My doctor has ordered an IVP. What is that? An IVP is an xray exam of the kidneys, ureters and bladder that uses iodinated contrast material injected into a vein. When the contrast material is injected into a vein, it travels through the blood stream and collects in the kidneys and urinary tract. The physician and radiologist can then view and assess the anatomy and function of the kidneys, ureters and the bladder. Common uses for IVP include the detection of problems due to: kidney stones, enlarged prostates, tumors in the kidneys, ureters or bladder and congenital anomalies.
How do I prepare for an IVP? You will be asked not to eat after midnight the night prior to your procedure. You may drink prior to your exam. You will also need to take a laxative the afternoon before your exam. This helps to clean out your intestines and makes visualization of your urinary system easier. If you have an allergy to IV contrast dye, please inform your care team immediately. It may be necessary to prep you with steroids prior to the procedure.
How will I feel during the IVP? The IVP is a relatively comfortable procedure. You may feel a minor sting as the contrast material is injected into your arm. Some patients may experience a flush of warmth and a metallic taste in their mouth. Usually these sensations disappear within a minute or two. During the process, you may be asked to turn from side to side and hold several different positions. Near the end of the exam, you will be asked to empty your bladder so an additional xray can be taken of the bladder after it empties. The contrast will not discolor your urine or cause any discomfort during urination.
