What is IVP (Intravenous Pyelogram)?

An IVP examination is a series of X-rays to show your child's kidneys and bladder (the urinary system).  It is performed in the Department of Medical Imaging at The Children’s Hospital at Westmead.

What happens in an IVP examination?

The test is done with your child lying on an X-ray table with an overhead camera. A canula will be inserted into a vein which will stay until the test is completed. The Radiologist will give your child an injection of contrast (medical dye).  It is like having a needle for a blood test.  The injection normally gives your child a warm feeling and a funny taste in the mouth.  However this sensation wears off quickly.  X-rays are then taken at timed intervals to show the kidneys, ureters and bladder. The test takes between half an hour to two hours to complete.

What is contrast?

Contrast is a clear liquid containing radiopaque substances (iodine based), which makes the bladder and kidneys able to be visualised.   It passes out very quickly in the urine. Details of the contrast will be discussed at the time of the examination. However, if you are aware of any allergies or abnormal kidney function please let the staff know at the time of booking.
