Urography

Is an examination used to evaluate the kidneys, ureters and bladder. Excretory urography, also known as intravenous pyelogram, is performed using conventional x-ray after the intravenous administration of radiographic contrast material.

Urography  purposes:

  • To evaluate the size, shape, structure, and function of the kidneys, ureters, and bladder
  • To aid in the diagnosis of urinary tract disorders, such as kidney stones, tumors, recurring infections, cysts, congenital abnormalities, or traumatic injury
  • To evaluate blood flow to the kidney and aid in the diagnosis of renovascular hypertension (increased blood pressure due to narrowing of the artery that leads to the kidney)
  • To identify damage to the urinary tract from injury or infection and other problems causing kidney malfunction or obstruction
  • pain in the kidneys
  • suspected kidney stones
  • blood in the urine
  • suspected obstruction
  • suspected congenital (inherited) abnormalities.

Preparation

Your kidneys have to be able to filter the dye. Therefore, it is seldom performed if you have kidney failure. Before the procedure you may need a blood test to check that you do not have kidney failure.

Tell your doctor if you have any allergies, especially allergy to contrast dyes such as iodine.

You may be asked not to eat for several hours before the procedure. This ensures that your gut (intestines) is empty of food, which makes the X-ray pictures clearer.

You may be given some laxatives to take for a day or so before the procedure. The aim of this is to clear the intestines, which will make the X-ray pictures clearer.

You may be asked to sign a consent form to confirm that you understand the procedure.

If you have diabetes and take a medicine called metformin you may need to stop the metformin for two days prior to the procedure. This is because the combination of metformin and contrast dye may affect the kidneys. (You should discuss this, and how to manage your diabetes over this period, in more detail with your doctor.)

How is it done

You will be asked to wear a gown and to lie on a couch. Contrast dye is then injected into a vein in your hand or arm. This may sting a little. The dye then starts to filter through the kidneys into the tubes which go from each kidney to the bladder (the ureters).

A series of X-ray pictures is then taken over your tummy (abdomen), usually every 5-10 minutes. You stay on the couch between each X-ray picture; however, you may be asked to get up to empty your bladder before the final X-ray picture is taken. The procedure usually takes about 30-60 minutes. Some pictures, however, may be taken hours later in certain circumstances.

You should be able to go home as soon as the procedure is finished. You can eat normally straight afterwards.

Contraindications: pregnancy (x-rays can negatively affect fetus development), x-ray examination with a barium suspension in the last four days, the inability of the patient to be stationary for even a short period of time, obesity (pictures can be fuzzy and uninformative).

  • 3 days prior to exam exclude gas-forming foods: beans, rye bread, cabbage, milk, yeast products, brown bread, fruit juices.
  • Take activated carbon when flatulence on doctor's order
  • Avoid having meal for 18-20 hours before the exam.
  • The day before exam take laxative on doctor's order before dinner, limit fluid intake from the afternoon
  • Do not eat, do not drink, do not smoke. Do not do any injections in the morning before exam.
  • Empty the bladder before exam.
  • Chronic pyelonephritis

  • Kidney stones

  • Renal cell carcinoma (RCC)

  • Transitional cell carcinoma (TCC)

  • Polycystic kidneys

  • Anatomical variations, i.e. horseshoe kidney or a duplex collecting system

  • Obstruction (commonly at the pelvic-ureteric junction or PUJ and the vesicoureteric junction or VUJ)

  • Pregnancy
  • Acute and chronic renal failure
  • Allergic reactions to contrast agents that contain iodine
