A retrograde pyelogram is a quick, relatively painless procedure that helps identify abnormalities in your urinary tract. It can also help your doctor do other urinary procedures or surgeries safely.

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. This procedure is performed with cystoscopy by placement of an endoscopic camera via the urethra into the bladder.

Although invasive, RP allows confirmation of the radiologic diagnosis while also facilitating ureterorenoscopy with biopsy or brushing and cytologic examination of localized urine collections. Renal ultrasonography and diuretic renogram are universally utilized to assess a patient prior to pyeloplasty; however, the role of retrograde pyelography at the time of pyeloplasty is still debatable , , . Herein, we describe two cases where the use of retrograde pyelography preoperatively helped to avoid pyeloplasty failure by allowing the surgeon to visualize a concurrent ureterovesical junction obstruction, which would not have been visible in the surgical field had the procedure been Examples are given that demonstrate that all the other diagnostic methods, including abdominal aortography, cystoscopy and retrograde pyelography, may be misleading in the diagnosis of renal agenesis or a non-functioning small kidney. In renal agenesis the lobar veins of the kidney are absent and only the non-renal tributaries of the renal vein, i.e. adrenal and sex veins, are visualized. The AP projection does not demonstrate C2. In addition, the patient cannot open his mouth because of a mandible fracture. A retrograde pyelogram is a specific

Precautions & Guidelines - Admission to 2021-01-06 · Retrograde pyelography Used to confirm a diagnosis of ureteropelvic junction (UPJ) obstruction and to characterize the obstruction for interventional planning. May also be indicated to better visualize the location of an obstruction (due to a stone, tumor , etc.) if prior imaging is insufficient. 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 likewise an intravenous pyelogram (IVP).

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.

The highest degree of efficiency of retrograde pyelography can be attained only by practising pyeloscopy. 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.

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, particularly the ureter and kidney Se hela listan på news-medical.net On multivariate analysis, receipt of contrast in the lower urinary tract (odds ratio [OR]: 1.8; p=0.04) or upper urinary tract by retrograde pyelography (OR: 1.6; p=0.04) or antegrade pyelography (OR: 2.0; p=0.007) increased the risk of AR compared with control patients. 2019-09-19 · Retrograde Pyelography 1.
