Intravenous Pyelogram (IVP) with contrast is a diagnostic procedure that involves taking X-ray pictures of the urinary tract, which includes the kidneys, ureters, and bladder. This test is performed using a contrast dye, which is injected into the veins to make the urinary tract more visible on the X-ray images. By highlighting the urinary tract, the doctor can observe if there are any abnormalities such as kidney stones, tumors, or blockages that affect the function of the urinary system.
The contrast dye used in IVP contains iodine. When injected into the bloodstream, it travels to the kidneys, where it is filtered and then passes through the ureters to the bladder. This process allows for a series of X-rays to be taken which can provide detailed images of the entire urinary tract.

Before you undergo an IVP with contrast, it’s crucial to follow these instructions:
Fasting: You may be asked to fast for 8-12 hours before the procedure. This is to ensure that the stomach and intestines are clear, as food and fluids can sometimes obscure the X-rays.
Allergies: Inform your doctor if you have any allergies, especially to iodine, as the contrast dye contains iodine. In some cases, pre-medication might be required to prevent allergic reactions.
Medication: Notify the doctor about any medications you are taking, as you might be advised to stop certain medications before the test.
Hydration: Drink plenty of water unless advised otherwise by your doctor, as this helps in the filtration process of the kidneys.
Pregnancy: If you are pregnant or suspect you might be, inform your doctor as radiation can be harmful to the fetus.
Clothing: Wear comfortable and easily removable clothing as you will be asked to wear a hospital gown during the procedure.
You will lie on an X-ray table, and a series of initial X-rays will be taken. A contrast dye is then injected into your vein, usually in the arm. Additional X-rays are taken at different time intervals to observe the dye as it travels through the urinary tract.
An IVP with contrast is used to examine the kidneys, ureters, and bladder. It helps in detecting kidney stones, tumors, or structural abnormalities. It is also used to evaluate recurrent urinary tract infections.
The test usually takes about an hour, but it can vary depending on how quickly the dye passes through your system.
Risks include exposure to radiation and allergic reactions to the contrast dye. It is important to notify your doctor if you have any allergies, especially to iodine.
You can usually go home after the procedure. It’s important to drink plenty of water to help flush the dye out of your system.
Your doctor will review the X-rays and discuss the findings with you. Depending on the results, further tests or treatments may be recommended.
Yes, you can resume your regular diet unless instructed otherwise by your doctor.
Yes, alternatives include ultrasound and CT scans. These might be used depending on your health status and the information needed.
If you experience any unusual symptoms such as difficulty breathing, swelling, or skin rash after the procedure, seek medical attention immediately.
Make sure to arrange for transportation home, as some patients might feel light-headed or nauseous after the procedure.
IVP with contrast is an effective diagnostic tool that provides valuable information about the urinary tract. It’s essential to follow your doctor's instructions before and after the test to ensure its success and your safety.
