Pyelogram
Pyelogram
Pyelogram (/paɪˈɛləɡræm/), also known as Pyelography or Urography, is a diagnostic imaging procedure used to visualize abnormalities in the renal pelvis and the ureter. The term is derived from the Greek words 'pyelo' meaning 'pelvis' and 'gram' meaning 'something written or recorded'.
Procedure
A Pyelogram involves the injection of a contrast medium into the patient's bloodstream. This contrast medium is then excreted by the kidneys and can be seen on an X-ray, which allows the doctor to see the structure and function of the kidneys, ureters, and bladder. There are two types of Pyelogram: Intravenous Pyelogram (IVP) and Retrograde Pyelogram.
Intravenous Pyelogram
An Intravenous Pyelogram (IVP) is a type of X-ray examination that uses a contrast medium to visualize the kidneys, ureters, and bladder. The contrast medium is injected into a vein and travels through the bloodstream to the kidneys, where it is excreted into the urine.
Retrograde Pyelogram
A Retrograde Pyelogram is a procedure where a urologist or radiologist will directly inject a contrast medium into the ureter to visualize the upper part of the urinary tract.
Indications
A Pyelogram is often used to diagnose conditions such as kidney stones, tumors, or blockages in the urinary tract. It can also be used to assess damage after a kidney injury or surgery.
Risks
As with any medical procedure, there are potential risks associated with a Pyelogram. These may include allergic reactions to the contrast medium, infection, kidney damage, or radiation exposure.
