CT urography ( CTU or CT IVU ), also known as CT intravenous pyelography ( CT IVP ), has now largely replaced traditional IVU in imaging the genitourinary tract. With the widespread implementation of CT urography, it is critical for radiologists to understand normal ureteral anatomy and the varied appearance of pathologic ureteral conditions at CT. There are other useful and cheap methods for evaluating ureteric fistula including the use of dye test. …. Magnetic resonance urography (MR urography) is a MRI study that predominantly used to image congenital abnormalities of the urinary system. In these times of rapid advances in radiographic imaging, intravenous urography should be performed in an optimal way. Dynamic renal scintigraphy is the gold standard technique to evaluate drainage curves and split renal function (SRF). Duplication occurs when 2 separate ureteric buds arise from a single Wolffian duct. Hematuria can be well evaluated with a comprehensive contrast material–enhanced multi–detector row computed tomography (CT) protocol that combines unenhanced, nephrographic-phase, and excretory-phase imaging. Little scientific evidence exists concerning optimal pressure while performing an APG. Introduction. The procedure involves introducing contrast into the urinary system in a retrograde fashion with simultaneous imaging using dynamic fluoroscopy. Appropriate therapy is ureteronephrectomy if the lesion is unilateral with secondary hydronephrosis and. planes of view. A loopogram is a fluoroscopic study of an ileal conduit. The purpose of this study was to determine whether a saline bolus during CT urography improves urinary collecting system opacification and whether the addition of enhanced CT digital radiography (CTDR) improves urinary collecting system visualization with or without a saline bolus. [2] [3]The urographic nephrogram is an important indicator of underlying functional and structural renal disease. Citation, DOI, disclosures and article data.
