You see a film of retrograde pyelography showing left ureter injury, you can see the dye leaking from the injured part of ureter.

Spot films taken in the appropriate obliquity during the fluoroscopic retrograde pyelogram demonstrated no defect, indicating that the defect was produced by extrinsic pressure, probably from a vessel (fig. 4, C). Fluoroscopy or oblique films during the IVP would probably have solved the problem more simply. Case 5.

2019-09-19 Retrograde urography requires ureteral catheterization so that a contrast medium can be introduced directly into the pelvicalyceal system. This procedure provides excellent opacification and structural information but does not demonstrate the function of these structures. Intravenous studies such as the IVU demonstrate function. A retrograde pyelogram is an imaging test that uses X-rays to look at your bladder, ureters, and kidneys.

You may have a retrograde pyelogram if: The IVP does not show a reason for your urinary symptoms.

Abdominal ultrasound (US) demonstrates hydronephrosis & proximal third hydroureter. The findings on IVU while suggestive of circumcaval ureter are not diagnostic. IVU usually does not demonstrate the middle and distal ureter requiring a RGP to demonstrate the ureter and hence confirm the diagnosis. A

Types include: Intravenous pyelogram In which a contrast for assessing the anatomical location of the obstruction. Antegrade or retrograde pyelography will show similar findings to an IVU but offer a therapeutic Abstract. Fifty-five antegrade pyelograms have been carried out, and the indications for this investigation reviewed. Whilst an inadequate intravenous urogram together with a failed or impossible retrograde pyelogram remains the absolute indication for antegrade pyelography, we have also often bypassed the need for retrograde pyelography in our patients.

Retrograde pyelography does not demonstrate

Spot films taken in the appropriate obliquity during the fluoroscopic retrograde pyelogram demonstrated no defect, indicating that the defect was produced by extrinsic pressure, probably from a vessel (fig. 4, C). Fluoroscopy or oblique films during the IVP would probably have solved the problem more simply. Case 5.

The procedure involves introducing contrast into the urinary system in a retrograde fashion with simultaneous imaging using dynamic fluoroscopy. This procedure is performed with cystoscopy by placement of an endoscopic camera via the urethra into the bladder. Spot films taken in the appropriate obliquity during the fluoroscopic retrograde pyelogram demonstrated no defect, indicating that the defect was produced by extrinsic pressure, probably from a vessel (fig. 4, C). Fluoroscopy or oblique films during the IVP would probably have solved the problem more simply. Case 5. You may have a retrograde pyelogram if: The IVP does not show a reason for your urinary symptoms.

2019-01-16 · Retrograde pyelography plays an important role in the management of ureteropelvic junction obstruction (UPJO). Once UPJO has been diagnosed, retrograde pyelography is used to confirm the diagnosis and to determine the exact location and nature of the obstruction. This procedure can be done prior to or at the time of planned intervention for UPJO. The retrograde pyelography demonstrated duplicated renal collecting systems on the left and a fine developing degree of right lower pole moiety; it did not show the upper pole moiety on the right, which suggested that the ectopic ureter was on the right side and the ectopic orifice might be inserted extravesically. Magnetic Resonance Imaging (MRI) can nicely demonstrate the course of a Pre-ureteral vena cava and may be a more detailed and less invasive imaging modality, without exposure to radiation, when compared with CT and RGP [2]. However, it may not be practical in our setting due to its high cost and limited availability in some health centers. What is Retrograde Pyelography?

Se hela listan på uuanj.com However, diagnostic retrograde studies are performed rarely in obstruction, only when renal function is impaired and other imaging modalities are inconclusive, but mainly for selective urine sample collection in suspected tumor, and prior to URS and double‐J stent placement. Possible complications of retrograde pyelogram include: Sepsis.

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.
