We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Digital Intravenous Urography (IVU or IVP) is a diagnostic imaging technique used to visualize the urinary system, including the kidneys, ureters, and bladder. It involves the intravenous administration of a contrast agent, typically an iodine-based solution, followed by a series of X-ray images or computed tomography (CT) scans.

Principles and Applications

The contrast agent is excreted by the kidneys and travels through the ureters into the bladder, allowing the visualization of the entire urinary tract. This technique is particularly useful for detecting obstructions, anatomical abnormalities, tumors, or other conditions affecting the urinary system.

IVU can help diagnose various conditions, including:

• Kidney stones
• Congenital anomalies of the urinary tract
• Tumors or masses in the kidneys, ureters, or bladder
• Urinary tract obstructions
• Vesicoureteral reflux (backflow of urine from the bladder into the ureters)

Procedure and Imaging

During an IVU procedure, the patient is typically asked to lie down on an X-ray table or a CT scanner. The contrast agent is then administered intravenously, and a series of X-ray or CT images are taken at specific time intervals as the contrast agent travels through the urinary system.

IVU is a valuable diagnostic tool, but it may not be suitable for certain patients, such as those with impaired renal function or allergies to contrast agents. Alternative imaging techniques, like ultrasound or magnetic resonance imaging (MRI), may be recommended in such cases.

Role of Digital Intravenous Urography

Digital Intravenous Urography (IVU) is an imaging technique used to evaluate the structure and function of the urinary system, including the kidneys, ureters, and bladder. It provides valuable diagnostic information for various urological conditions by visualizing the flow of contrast material through the urinary tract.

Indications for Digital Intravenous Urography

Digital Intravenous Urography may be recommended in the following situations:

• Evaluation of suspected obstructions or blockages in the urinary tract, such as kidney stones or tumors.
• Assessment of congenital abnormalities or anatomical variations in the kidneys or urinary tract.
• Investigation of suspected kidney or bladder injuries or trauma.
• Monitoring of kidney function and assessment of potential kidney diseases.
• Evaluation of recurrent urinary tract infections or hematuria (blood in urine).

Preparation for the Digital Intravenous Urography Procedure

Before undergoing a Digital Intravenous Urography (IVU) procedure, several preparatory steps may be required:

• Dietary restrictions: You may be instructed to follow a specific diet or restrict certain foods and beverages prior to the procedure, particularly those that may interfere with the contrast agent or imaging results.
• Hydration: Adequate hydration is crucial to ensure proper visualization of the urinary tract. You may be advised to drink plenty of fluids in the hours leading up to the procedure.
• Medication review: Inform your healthcare provider about any medications, supplements, or herbal products you are taking, as some may need to be adjusted or discontinued temporarily.
• Pregnancy precautions: IVU is generally avoided during pregnancy due to the potential risks associated with radiation exposure. Inform your healthcare provider if you are or suspect you may be pregnant.
• Allergy screening: Inform your healthcare provider if you have any known allergies, particularly to contrast agents or iodine, as precautions may need to be taken.

Digital Intravenous Urography Procedure

The Digital Intravenous Urography procedure typically involves the following steps:

1. An intravenous (IV) line will be inserted into your arm or hand to administer the contrast agent.
2. You will be positioned on the imaging table, and the healthcare provider will take preliminary images before administering the contrast agent.
3. The contrast agent will be injected through the IV line, and you may experience a warm sensation or metallic taste, which is normal.
4. Multiple X-ray images will be taken at different intervals as the contrast agent travels through your urinary tract, capturing images of the kidneys, ureters, and bladder.
5. You may be asked to hold your breath or change positions during the imaging process to obtain clear images.

IMPORTANT!

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or exacerbation of a condition, it is essential to consult a healthcare professional for appropriate diagnostic tests. Only a qualified specialist can provide an accurate diagnosis and determine the appropriate treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
