Urography
Urography
Urography (pronounced: u-rog-raphy, from the Greek words "ouro" meaning urine and "graphia" meaning writing) is a radiographic examination of the urinary system. It is used to diagnose and monitor conditions related to the kidneys, bladder, and ureters.
Types of Urography
There are two main types of urography: Intravenous Urography and Retrograde Urography.
- Intravenous Urography (IVU), also known as Intravenous Pyelogram (IVP), involves injecting a contrast dye into a vein, which then travels through the bloodstream and into the kidneys. This allows for detailed images of the urinary tract to be taken.
- Retrograde Urography involves the direct insertion of a contrast dye into the bladder and ureters through a cystoscope. This method is typically used when IVU is not possible or has not provided sufficient information.
Procedure
The procedure for urography varies depending on the type of urography being performed. However, both types involve the use of a contrast dye to highlight the urinary tract in radiographic images. The patient may be asked to fast for a certain period before the procedure and to drink plenty of fluids afterwards to help flush out the contrast dye.
Risks and Complications
As with any medical procedure, there are potential risks and complications associated with urography. These may include allergic reactions to the contrast dye, infection, and damage to the urinary tract. Patients with kidney disease or certain other medical conditions may be at higher risk of complications.
