An intravenous pyelogram (IVP) is an imaging test that uses a contrast medium (radiopaque iodine) and x-rays to produce images of the urinary tract (kidneys, bladder, ureters and urethra). The radiopaque iodine concentrates in the urine. The x-rays show the size, shape and position of the urinary tract. The IVP also shows kidney function and how well the bladder empties. The IVP is usually done as an outpatient procedure in the x-ray department of a hospital or clinic. The test usually takes about 1 hour to complete. It is important for women to tell the x-ray technologist or radiologist if they are breast-feeding, pregnant or think they may be pregnant before having any type of x-ray. Preparation for an IVP can vary, but usually includes: No eating or drinking for 12 hours before the IVP. Taking a laxative the evening before the IVP. Having an enema the morning of the IVP. A preliminary x-ray may be taken to make sure the colon is empty. A blood test may be done to make sure the kidneys are functioning well enough. The person is asked to remove clothing, jewellery and other objects that will be in the x-ray field and may interfere with the quality of the x-ray. During the test: -The person lies on the back and an x-ray of the abdomen is taken to make sure the colon is empty and to see the location of the kidneys. - The radiopaque iodine is injected, usually into the vein that runs through the bend in the arm. - During the injection, the person may feel warm, flushed, have a salty taste in the mouth or feel nauseated. - People may be told to take slow, deep breaths if these feelings occur. The person is asked to stay very still while the x-rays are taken. - At least 3 x-rays, several minutes apart, are taken as the radiopaque iodine travels through the urinary tract. - The person may be asked to turn from one side to the other or to hold different positions so other x-rays can be taken. - The person is asked to urinate, and then a final x-ray is taken. - An x-ray procedure that projects the motion or activity of internal organs onto a screen (called fluoroscopy) may be used during an IVP. After the test, the person will be instructed to drink plenty of fluid to help flush the radiopaque iodine from the body. Renz Figueroa Blanca II
