Steven B. Oglevie MD, in Vascular and Interventional Radiology (Second Edition), 2006 Access for Diagnostic Interventions. Percutaneous access may be performed to permit antegrade pyelography. The collecting system may be better imaged with direct contrast injection than with excretory urography, particularly in cases of high-grade urinary obstruction (Fig. 23-6).

Retrograde pyelography remains useful for characterizing filling defects detected on other modalities, such as IVU and CTU. Haematuria: an imaging guide Anterograde or retrograde pyelography reveals horizontally redundant ureter posterolateral and inferior to the ischial spine. Pyelography is superior to all other imaging techniques for the demonstration of fine detail in the pelveocalyceal system and the ureter. For almost 90 years it has been performed through a retrogradely inserted catheter, but during the recent 30 years antegrade injection via a transparenchymally inserted needle or catheter has become an accepted alternative, especially in case of a dilated 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.

In addition, it may demonstrate poor distensibility of the ureters, as depicted in the images below. {file40006 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 pyelography: pyelography in which contrast material is injected into the ureters from an endoscope in the bladder. Percutaneous fine needle aspiration biopsy was performed at retrograde pyelography in order to differentiate between metastatic and scarry involvement of a strictured ureter in a patient earlier operated upon because of malignant teratoma.

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 in 140 transplanted kidneys within 3 days of the operation showed a high frequency (29%) of pyelorenal backflow. Pyelotubular backflow, ordinarily a rare form of backflow, was seen in one-third of the patients whose transplants were removed within 60 days because of rejection, but in only 4% of the patients with surviving grafts. Intravenous pyelography uses a similar dye, but it is injected directly into a vein and travels to the kidneys via the bloodstream.

This test is usually done during a test called cystoscopy. 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 be attained only by practising pyeloscopy. 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.

This study intends to evaluate the utility of this imaging combination in terms of the yield of abnormal findings on the follow up RPG. In this retrospective study, we searched the radiology database over a three-year period (11/1/2015–10/30/2018) for 2019-01-16 · 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 Part 2 of the Procedure "Flexible Ureteroscopy and Laser Lithotripsy of Lower Pole Stones"Watch this procedure on the MAESTRO-Portal: http://www.maestro-port Retrograde Pyelography Retrograde pyelography is performed when the ureters are poorly visualized on other imaging studies or when samples of urine need to be obtained from the kidney for cytology or culture. Patients who have severe allergies to contrast agents or impaired renal function can be evaluated with retrograde pyelography. Retrograde pyelography revealed no suspicious formation in the right ureter or pelvis. Extensive Renal Arteriovenous Malformations Treated by Transcatheter Arterial Embolization [4] This entity is usually diagnosed by invasive tests (Voiding Cystourethrography or Retrograde Pyelography ), but in our case we emphasized the role of non-invasive tests (IVU and CT Urography) in the diagnosis of these entity.
