What is urography antegrade?
An antegrade pyelogram is an imaging test to find a blockage (obstruction) in the upper urinary tract. Your urinary tract includes the kidneys, ureters, and bladder. The ureters are the narrow tubes that carry urine from the kidneys to the bladder.
What does it mean when there is antegrade filling of contrast media in the kidney?
In that test, the contrast dye was injected into a vein instead of into your kidney or ureter. The antegrade pyelogram can find a blockage in the urinary tract caused by: Narrowing of the ureter (stricture) Kidney stone.
What is urography retrograde?
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 percutaneous antegrade pyelography?
Percutaneous antegrade pyelography allows the clinician to evaluate the renal pelvis and ureter, to localize the ureteral obstruction, and to determine whether the obstruction is partial or complete (17).
What is the difference between IVP and IVU?
An intravenous urogram (IVU) is a test that looks at the whole of your urinary system. It’s sometimes called an intravenous pyelogram (IVP). It looks at the: kidneys.
How is a retrograde urethrogram performed?
You will lie on your back or side, and an x-ray of the urethra and bladder are taken. X-ray contrast agent (dye) is gently moved into your urethra. This may not be comfortable, but it doesn’t take long. More x-rays are taken with the dye to see your urethra more clearly.
What does antegrade mean?
Definition of anterograde 1 : occurring or performed in the normal or forward direction of conduction or flow: such as. a : occurring along nerve processes away from the cell body anterograde axonal transport — compare retrograde sense 1c(1)
What is the difference between an IVU and a retrograde Urogram?
Retrograde pyelography uses a special dye (“contrast agent”) injected into the ureters. The dye makes the ureters and kidneys more easily seen on the x-ray. This test is like an intravenous pyelogram (IVP). But with IVP, the dye is injected into a vein instead of the ureter.
How antegrade pyelogram is done?
An antegrade pyelogram is a type of x-ray used to diagnose an obstruction of the upper urinary tract. During the procedure, a contrast dye is injected into a portion of the ureter (narrow tube that carries urine from the kidney to the bladder) closest to the kidneys called the renal pelvis.
What urography means?
Urography is an examination used to evaluate the kidneys, ureters and bladder. Excretory urography, also known as intravenous pyelogram, is performed using conventional x-ray after the intravenous administration of radiographic contrast material.
What is an antegrade stent?
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.
Why is intravenous urography performed?
An intravenous pyelogram (PIE-uh-low-gram), also called an excretory urogram, is an X-ray exam of your urinary tract. An intravenous pyelogram lets your doctor view your kidneys, your bladder and the tubes that carry urine from your kidneys to your bladder (ureters).
How is intravenous urography done?
The urinary tract does not show up well on ordinary X-ray pictures. However, with intravenous urography a contrast dye is injected into a vein (‘intravenous’ injection). The dye travels in your bloodstream, concentrates in your kidneys, and is passed out into your ureters with urine made by your kidneys.
When is a retrograde urethrogram used?
A retrograde urethrography is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra. Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture.
Is retrograde urethrogram painful?
No, the procedure does not involve any injections. When the local anesthesia solution is introduced you will only have a discomfort. But if you have pain, immediately report to your Doctor and the procedure may be abandoned. This procedure does not involve any adverse reaction of the contrast agent used.
Is antegrade blood flow normal?
VERTEBRAL ARTERIES Confirm the flow is antegrade i.e. towards the head – (normal) or retrograde (suggesting subclavian steal syndrome).
What does normal antegrade flow mean?
What is retrograde contrast?
Retrograde pyelography is a form of x-ray used to get detailed pictures of the ureters and kidneys. Retrograde pyelography uses a special dye (“contrast agent”) injected into the ureters. The dye makes the ureters and kidneys more easily seen on the x-ray. This test is like an intravenous pyelogram (IVP).
What is the meaning of pyelogram?
noun. the science or technique of making photographs of the kidneys, renal pelves, and ureters by means of x-rays, after the injection of an opaque solution or of a radiopaque dye.
What is the difference between intravenous pyelogram and retrograde pyelogram?
Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system. Retrograde pyelogram – Any pyelogram in which contrast medium is introduced from the lower urinary tract and flows toward the kidney (i.e. in a “retrograde” direction, against the normal flow of urine).
