Retrograde pyelography is used by many urologists to visualize the ureters and collecting system of the kidney. The procedure involves introducing contrast into the urinary system in a retrograde fashion with simultaneous imaging using dynamic procedure is performed with cystoscopy by placement of an endoscopic camera via the urethra into the bladder.
Reasons for performing a retrograde pyelogram include identification of filling defects (e.g. stones or tumors), as an adjunct during the placement of ureteral stents or ureteroscopy, or to delineate renal anatomy in preparation for rade pyelography is generally done when an intravenous excretory study (intravenous pyelogram or contrast CT scan) cannot be done because of renal ICD 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).
But with IVP, the dye is injected into a vein instead of the ureter. Pyelovenous Backflow. Single image from a retrograde pyelogram shows the catheter (dotted white arrow) in the left ureter.
There is a slightly dilated collecting system (dotted yellow arrow). There is extraluminal contrast in venous structures (yellow arrow), including the left renal vein (white arrow).

The term is most often encountered in 'intravenous pyelography' (or "IVP"). For some, this is a misnomer and a test that images intravenous contrast as it travels through the kidney parenchyma into the urinary collecting system should only be called 'intravenous urography'.
A retrograde pyelogram is a procedure that gives your doctor a better view of your urinary system. Learn about the risks and what you need to do to prepare.
retrograde pyelography: pyelography in which contrast material is injected into the ureters from an endoscope in the bladder. Pyelolymphatic backflow phenomenon, which is a subtype of pyelorenal backflow, is a rare condition that occurs during the acute phase of urinary obstruction.
Pyelorenal backflow has already been described in humans with retrograde pyelography. Our report presents a rare case of pyelolyphatic backflow demonstrated by a computed by: 3. Antegrade pyelography is the procedure used to visualize the upper collecting system of the urinary tract, i.e., kidney and is done in cases where excretory or retrograde pyelography has failed or contraindicated, or when a nephrostomy tube is in place or delineation of upper tract is desired.
It is commonly used to diagnose upper tract obstruction, hydronephrosis, and ureteropelvic Purpose: visualize the upper collecting system of the urinary tract.

Loading Unsubscribe from MAESTRO. Ureteral Obstruction - Retrograde insertion of Resonance stent - Duration: 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.
Retrograde pyelography is used by many urologists to visualize the ureters and collecting system of the kidney.
The procedure involves introducing contrast into the urinary system in a retrograde fashion with simultaneous imaging using dynamic fluoroscopy. A kidney X-ray, known as a retrograde pyelography, is a test that helps your doctor look at how your urinary system is working and check that the shape and size of your organs are normal.
Your urinary system includes your two kidneys and the bladder, the tube that connects each kidney to the bladder (ureters), and the tube that carries urine. Like an IVP, retrograde pyelography uses a contrast material to produce x-ray images of the ureters and kidneys.
However, in retrograde pyelography, the dye is injected directly into the ureters rather than into a vein. Retrograde pyelography is performed on an outpatient basis and is usually done in the doctor’s office or a surgical center.

X-ray photography of the renal pelvises and the urinary tract in which visualization is enabled by the injection with a radiopaque contrast medium. You see a film of retrograde pyelography showing left ureter injury, you can see the dye leaking from the injured part of ureter.
Abstract. Retrograde pyelography involves taking X-rays of the kidney and ureter by injection of contrast through a ureteric stent. This is done mainly for diagnostic indications, including diagnosis of the level of ureteric obstruction and looking for intrinsic lesions of the ureter and kidney that were not very clear on intravenous pyelography.

pyelography: [ pi″ĕ-log´rah-fe ] radiography of the renal pelvis and ureter after injection of a contrast medium; there are two methods: the intravenous method and the retrograde method. Preparation of the patient for pyelography includes clearing the intestinal tract of as much fecal material and gas as possible so that there can be adequate.
Excretion urography has not supplanted retrograde pyelography as some would have us believe, but has made retrograde pyelography the more accurate procedure in roentgenologic diagnosis of renal pathology.
The highest degree of efficiency of retrograde pyelography can. Intravenous pyelography (IVP) is a diagnostic test that uses X-rays and a contrast dye to image the kidneys, bladder, and ureters for kidney stones, bladder stones, UTI and related issues.
This dye, also known as contrast medium, is iodine-based and allows doctors to see parts of the body that do not otherwise show up on x-rays. Conventional radiologic studies with retrograde contrast administration via cystoscopically inserted ureteral catheters or anterograde through percutaneous nephrostomies, both performed under fluoroscopic control, provide the most precise delineation of the collecting system.
However, diagnostic retrograde studies are performed rarely in obstruction, only when renal function is impaired and. Ugeskr LÃ¦ger ; Thomsen HS, Dorph S.

Pyelorenal backflow in normal and ischemic rabbit kidneys. To the contrary, retrograde pyelographic studies in man have shown that pyelorenal reflux occurs at higher pressures (80 to mm.) unless the normal caliceal anatomy has been distorted by underlying disease,11 These studies also indicate that pyelorenal reflux in man consists of pyelo venous, pyelolym- phatic, pyelointerstitial and Cited by: 7 ways to abbreviate Retrograde Pyelogram updated How to abbreviate Retrograde Pyelogram.
The most popular abbreviation for Retrograde Pyelogram is: rpg. Cystoscopy and Retrograde Pyelography. After cystoscopy a retrograde pyelography is done to evaluate the anatomy of the upper urinary tract and to review the indications for ureteroscopy. With help of a ureteral catheter, a guide wire is inserted up to the renal pelvis [fig.

Retrograde Urography Procedure Retrograde Urography is usually taken in AP Projection and positioned the patient in modified litothomy position, Retrograde urography is an examination of kidneys, ureters and bladder with the use and administration of contrast media.
Retrograde urography differs from excretory urography in that the contrast medium is injected directly into the kidney by means of a percutaneous injection through the skin.
false (contrast agents are injected into a selected renal pelvis by means of catheters that pass through the urethra, the bladder, & the ureter to the selected kidney).
A retrograde pyelogram is a type of X-ray that allows visualization of the bladder, ureters, and renal pelvis. Generally, this test is performed during a procedure called cystoscopy – evaluation of the bladder with an endoscope (a long, flexible lighted tube).
What is Retrograde Pyelography. Retrograde pyelography uses special contrast agent (dye) to produce detailed X-ray pictures of the ureters and kidneys. The difference is that in retrograde pyelography the dye is injected directly into the ureters rather than into a vein. It is better suited to see the definition of the upper urinary tract.
Patients were prospectively evaluated in terms of urinary symptomatology, physical examination, smoking habits, intravenous pyelography (IVP), abdominal ultrasonography (USG), Nuclear Matrix Protein 22 (NMP22), urine cytology and NMP22 BladderChek[R] test.
Retrograde pyelogram confirmed that the dilator was appropriately placed in the renal pelvis. Paradoxical air embolism during percutaneous nephrolithotomy due to patent foramen ovale: case report A ureteric catheter was placed alongside the Foley catheter and a retrograde pyelogram was performed (Figure 2).
Retrograde pyelography involves placing a rigid telescope (called a cystoscope) into your bladder and injecting contrast fluid into the tubes that connect each kidney to your bladder (ureters).
There is a small risk of infection and to reduce this risk, you must drink plenty of water throughout the first few days to help flush your kidneys and. The urologist or radiologist may also interpret the images (x-ray films or fluoroscopic images) and report (Urography, retrograde, with or without KUB).
For any retrograde pyelogram, you can report for the urologist's work. However, reporting depends. Medical definition of retrograde pyelography: pyelography performed by injection of radiopaque material through the ureter.Retrograde pyelography is a sort of x-ray utilized to obtain comprehensive pictures of the ureters and kidneys.
Retrograde pyelography uses a special mixture, injected into the ureters. The mixture fabricates the ureters and kidneys more easily seen on the x-ray.
This test is .A retrograde pyelogram was performed identifying the lower pole and upper pole of the left kidney. Calculi were present.
