What is antegrade urography?
What is Antegrade Pyelography? Antegrade pyelography uses a special dye to see detailed x-ray images of the upper urinary tract (kidney and ureter). It is used to diagnose hydronephrosis, ureteropelvic junction (UPJ) obstruction and obstruction of the ureters, for example.
What is an antegrade procedure?
As the stent is put in through the kidney and down the ureter, this is called an antegrade procedure (as opposed to placing a stent through the bladder and up the ureter, which is a retrograde procedure). This stent allows urine to drain in the normal fashion, from the kidney into the bladder.
What are the three phases of CT urogram?
The CT urogram is most commonly performed as a three-phase computed tomography technique used to evaluate the kidneys and urinary collecting system. The three phases most commonly include a non-contrast phase, a nephrographic phase scanned at 80 to 120 s delay, and an excretory phase scanned at 10–15 min delay (Fig.
What is antegrade ureteroscopy?
Antegrade ureteroscopy, using the 11-French ureteroscope via a percutaneous transrenal access, provides safe and easy endoscopic exploration of the ureter above the level of the iliac vessels.
What is CT Urogram used for?
A computerized tomography (CT) urogram is an imaging exam used to evaluate the urinary tract. The urinary tract includes the kidneys, bladder and the tubes (ureters) that carry urine from the kidneys to the bladder.
What is retrograde urography?
A retrograde pyelogram is an imaging test that uses X-rays to look at your bladder, ureters, and kidneys. The ureters are the long tubes that connect your kidneys to your bladder. This test is usually done during a test called cystoscopy. It uses an endoscope, which is a long, flexible, lighted tube.

What is the difference between CT urogram and CT urography?
Following the CT urogram, the radiologist will review and interpret the results. They will then forward the report to the person’s doctor. CT urography is a preferred technique for providing accurate information to diagnose many urinary tract problems, including: kidney and bladder stones.
Is a CT urogram painful?
Urography with conventional x-ray is known as intravenous pyelogram (IVP). Urography is also often performed using computed tomography (CT) or magnetic resonance imaging (MRI). CT and MR urography are painless and proven effective in detecting urinary tract issues.
Do you need a full bladder for a CT urogram?
Usually, you have to drink a certain amount of water before you arrive for your CT scan. This is so your bladder can get bigger and be seen more clearly on the pictures.
