What are the indications and contraindications of intravenous urography?

What are the indications and contraindications of intravenous urography?

Abdominal aortic aneurysm or other abdominal mass. Severe abdominal pain. Recent abdominal surgery. Suspected urinary tract trauma.

What is the difference between intravenous urography and intravenous pyelography?

Some prefer the term “urogram” to refer to visualization of the kidney parenchyma, calyces, and pelvis after intravenous injection of contrast, and reserve the term “pyelogram” to retrograde studies involving the collecting system. In practice, both terms are often used interchangeably.

What contrast is used for intravenous urography?

During an intravenous pyelogram, you’ll have an X-ray dye (iodine contrast solution) injected into a vein in your arm. The dye flows into your kidneys, ureters and bladder, outlining each of these structures.

What pathologies would indicate an IVU?

What is intravenous urography used for?

• Kidney stones. A stone in a kidney or in the tube which goes from a kidney to the bladder (the ureter) will normally show up quite clearly.
• Urine infections.
• Blood in the urine.
• Obstruction or damage to any part of the urinary tract can often be seen on an IVU.

What are the contraindications of IVU?

Known allergy to iodine is an absolute contraindication. Nausea and vomiting are common side effects that are generally self-limiting. Allergic reactions include urticaria, hypotension and bronchospasm. Contrast medium-induced renal failure is a rare, idiosyncratic reaction.

What blood test results do you need to check before she has an IVP?

To avoid this complication, the kidney function should be tested with a blood test for creatinine, and the results should be known before the IVP is performed. Those with diabetes who are taking metformin (Glucophage) will have to discontinue this medication prior to and for 2 days after the IVP.

Will I feel anything when the iodine is injected?

If Intravenous Contrast Is Used It contains iodine. Most patients will feel a warm sensation during or after the injection, but will have no reaction or side effects. However, there is a risk of reaction to the IV contrast.

Can ureters be seen on ultrasound?

Ultrasound can detect cysts, tumors, abscesses, obstructions, fluid collection, and infection within or around the kidneys. Calculi (stones) of the kidneys and ureters may be detected by ultrasound.

Is contrast dye hard on kidneys?

The dye may injure the kidneys by causing the blood vessels of the kidney to narrow, and damaging the structures inside the kidney, said study author Dr. Javier Neyra.

Will a CT scan show kidney problems?

CT scans of the kidneys are useful in the examination of one or both of the kidneys to detect conditions such as tumors or other lesions, obstructive conditions, such as kidney stones, congenital anomalies, polycystic kidney disease, accumulation of fluid around the kidneys, and the location of abscesses.

How do you prepare a patient for IVU?

Preparation: Medications can be taken prior to your test. Pills should be taken with only a small amount of water. If are diabetic and take insulin, you must consult your doctor to adjust your dose. You should not take insulin if you are fasting for this examination.

What organs does the IVP show?

What is an Intravenous Pyelogram (IVP)? IVP is an x-ray exam that uses a special dye to outline the kidneys, ureters and bladder. It can show how your renal and urinary system handles fluid waste. This helps your health care team find problems in the urinary tract.

What is IV test?

Intravenous pyelogram (IVP) is an x-ray exam that uses an injection of contrast material to evaluate your kidneys, ureters and bladder and help diagnose blood in the urine or pain in your side or lower back. An IVP may provide enough information to allow your doctor to treat you with medication and avoid surgery.

Why does iodine make you feel like you peed?

When the dye starts, it might feel like you are peeing your pants. Don’t worry, you won’t actually pee. It’s just a side effect of the dye.”

What happens if you pee before an ultrasound?

Pelvic ultrasound Don’t urinate (pee) before your ultrasound. Having a full bladder will make it easier to see your uterus and ovaries. If close-up views of the lining of your uterus and your ovaries are needed, you may have a transvaginal ultrasound after your pelvic ultrasound.

Can you see kidney failure on an ultrasound?

In order to diagnose kidney failure, your doctor may order: Renal ultrasound: This imaging exam uses high-frequency sound waves to view the kidneys in real time, and is often the first test obtained to examine the kidneys.

How do you protect your kidneys from contrast dye?

The inexpensive drug, called N-acetylcysteine, can prevent serious kidney damage that can be caused by the iodine-containing “dyes” that doctors use to enhance the quality of such scans. That “dye,” called contrast agent, is usually given intravenously before a CT scan, angiogram or other test.

Why is contrast hard on kidneys?

These medications can potentially cause a kidney problem by decreasing blood flow to the kidneys. Because contrast dyes can also decrease kidney blood flow, the two agents should not be given concurrently.

What color is urine when your kidneys are failing?

Light-brown Urine. Light-brown or tea-colored urine can be a sign of kidney disease or failure or muscle breakdown.

Does urography require contrast?

Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract. Urography with conventional x-ray is known as intravenous pyelogram (IVP).

While the tests and contrast dyes used are generally safe, the contrast eyes may lead to the development of kidney problems or cause problems in patients with kidney disease. During an MRI or CT with contrast, the radiology team injects contrast dye into an intravenous (IV) needle.

What is the difference between a CT scan and IVP?

A CT scan shows a cross-sectional view of the patient. In some cases, a CT study doesn’t need to use a contrast agent. It can often provide better information than an IVP. However, it does result in an increased amount of radiation.

How does contrast dye affect the kidneys?

Can you pee before a CT scan?

Are there any side effects or risks from intravenous urography?

Are there any side-effects or risks from intravenous urography? When the dye is injected you may have a flushing or warm feeling and a metallic taste in the mouth. These usually quickly go. An allergic reaction to the dye occurs in a small number of cases. Symptoms may be mild – for example, an itchy skin rash and some mild swelling of the lips.

Are there any side effects to intravenous contrast media?

The good news is that physiologic reactions are not life-threatening. The bad news is that there’s nothing your doctor can do to prevent them the way they can for allergy-like reactions. Another rare risk factor of intravenous contrast media is Contrast Induced Nephrotoxicity (CIN).

Can you use contrast in an intravenous pyelogram?

Intravenous pyelography is not the only type of medical test that uses contrast media. Dye is used in many medical tests and most of them use quite a bit more of it than an intravenous pyelogram does.

Special Procedure: Intravenous Urography (IVU) Severe dehydration. Uremia is not a contraindication as long as the patient is hydrated and producing urine. However, the diagnostic quality of the study may be compromised because of poor contrast concentration. In general, if the serum creatinine is > 3.5…
