The preparation required depends on the situation. If the
examination is needed urgently, then there is no preparation required.
However, if it is done with an appointment, the patient will need to fast
overnight and undergo bowel preparation. A bowel-cleansing agent to empty
the bowels will be given at the time of appointment. If the patient has a
history of asthma, allergy to iodine or history of reaction to iodinated
contrast media, drugs or any other allergies, the radiologist or
radiographer needs to be informed. At the time of the examination, the patient will lie on the
X-ray table. A radiograph will be taken before contrast medium is injected
into the patient’s vein. The radiologist will place a small needle into
an arm or hand vein. When the contrast medium is injected, the patient may
experience a warm feeling. This sensation disappears soon after injection.
A few more radiographs are taken after which a compression band is placed
over the lower abdomen to demonstrate the kidneys better. This may be a
little uncomfortable but should not affect the patient’s breathing. A
few more radiographs will be taken. Following release of the compression
band, the patient is required to empty the bladder and another radiograph
will be taken. Following the examination, there are no restrictions. There
are no significant long-term effects of IVU.

indicated in patients with problems related to the urinary system. This
examination will show the kidneys, ureters and bladder. An IVU is the
appropriate examination for investigation of blood in the urine (haematuria)
or loin pain in patients with kidney stones.
