Intravenous urography
About
Intravenous urography (IVU) is a diagnostic imaging procedure used to visualize the urinary system, including the kidneys, ureters, and bladder.
Candidate
Intravenous urography is recommended for individuals who may have symptoms or conditions related to the urinary system, such as blood in the urine, kidney stones, or unexplained pain. It can help diagnose various urinary tract conditions.
Preparation
Before an IVU, the patient may need to undergo some preparation, which can include fasting for a few hours before the test and taking medications to help enhance the contrast in the images. It's essential to inform the healthcare provider about any allergies, especially to iodine or contrast agents.
Treatment
During an IVU, a contrast agent containing iodine is injected into a vein, usually in the arm. The contrast material travels through the bloodstream and is filtered by the kidneys. X-ray images are then taken at different time intervals to capture the contrast material as it moves through the urinary system. The procedure may involve multiple X-ray images to obtain a comprehensive view.
Result
IVU results provide detailed images of the urinary system, helping doctors identify any abnormalities, blockages, or other issues. These images can be crucial for diagnosing conditions such as kidney stones, tumors, or structural problems in the urinary tract.
Precautions
While IVU is generally considered safe, it involves the use of contrast agents that some individuals may be allergic to. It's important to inform the healthcare provider about any allergies or pre-existing medical conditions. Additionally, women who are pregnant or breastfeeding should inform their healthcare provider before the procedure to assess the potential risks. After the IVU, it's essential to stay hydrated to help flush the contrast material out of the body.

F.A.Q.
Intravenous urography is a diagnostic procedure that uses X-rays to obtain images of the urinary system after the administration of contrast material through an intravenous (IV) catheter.
This procedure is commonly used to diagnose issues in the urinary system, such as stones, tumors, or other abnormalities.
Preparation may include fasting on the day of the exam, taking certain medications, and informing the doctor about any allergies to contrast agents.
Side effects are possible, including allergic reactions to the contrast material, nausea, or mild fever. It is important to inform the doctor about any previous allergic reactions.
In most cases, fasting on the day of the exam is recommended. The doctor may provide specific guidelines.
The duration of the procedure can vary, but it usually takes between 30 and 60 minutes, depending on the specific requirements of the examination.
Although the procedure involves X-rays, the exposure is typically low. It is important to consult with the doctor about potential risks and benefits.
Some patients may feel warmth or a metallic taste in the mouth after the administration of the contrast material, but these sensations usually pass quickly.
Pregnant women typically avoid X-ray examinations, so the doctor will assess the urgency of the procedure and potential risks during pregnancy.
