Retrograde pyelography is generally done when an intravenous excretory study (intravenous pyelogram or contrast CT scan) cannot be done because of renal disease or allergy to intravenous contrast. Relative contraindications include the presence of infected urine, pregnancy (because of radiation), or allergy to the contrast.

the tenet that retrograde pyelography must form part of Ureteric catheterization is not without its dangers; how- This shows a steady decline of ureteric.

remove a stent that was placed in the ureter after a ureteroscopy with biopsy or stone removal. Retrograde pyelography may sometimes be ineffective due to obstruction at the ureteropelvic junction. Traditional contrast material gastrointestinal examinations such as upper gastrointestinal series or barium enema study usually fail to demonstrate the tract. Retrograde pyelography uses a contrast dye to get detailed X-ray pictures of the upper urinary tract.

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. Urinary tract infection. Bladder tear. Bleeding.

In my opinion it does sound like the doctor is checking their work and there are no results dictated to what pathology was found during the retrograde pyelogram, for example, hydronephrosis, calcifications, filling defect, etc. A retrograde pyelogram may be performed on an outpatient basis or as part of your stay in a hospital.

retrograde pyelography, and ultrasonography, still play pivotal roles in MR imaging protocols can be used in patients who are not candidates shows a large irregular filling defect (arrow) involving the right renal pelvis and exten

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.

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.

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. The IVP cannot be done because of kidney problems such as chronic kidney disease. You are allergic to the iodine-based dye (contrast material) used in the IVP. Pregnant women normally do not have this test, because the X-rays may harm the unborn baby.

Possible complications of retrograde pyelogram include: Sepsis. Urinary tract infection. Bladder tear. Bleeding. Nausea or vomiting. You may not be able to have this test if you are severely dehydrated. You may have other risks depending on your specific health condition.

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. During a cystoscopy, the healthcare provider can inject contrast dye directly into the ureters. 1978-09-01 Retrograde urography is a radiographic procedure that demonstrates certain urinary structures.
