Intravenous urography (IVU), also referred to as intravenous pyelography (IVP) or excretory urography (EU), is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and the urinary bladder. This exam has been largely replaced by CT urography .

For two decades, computed tomography (CT) has challenged intravenous urography (IVU) in the evaluation of urinary tract abnormalities. Compared with IVU

Chapters detail the indications and techniques for CT urography, review the risks of radiation exposure, show how normal urinary tract anatomy and variants appear on CT scans, and demonstrate a wide range of urinary tract abnormalities as they appear on thin-section CT. Imaging plays a significant role in the initial diagnosis of UTO, with anatomic imaging (primarily ultrasound (US) and non-contrast computed tomography (CT)) serving as screening tools for the detection of the dilation of the urinary collecting systems (i.e., hydronephrosis). CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma. Initial imaging includes a noncontrast phase to detect renal calculi as a source of hematuria. CT Urography for Evaluation of the Ureter S E Potenta and others RadioGraphics, 2015. Volume 35, Number 3, Pages 709 – 726. The information on this page is based on literature searches and specialist checking.

Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam. 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 urography. Pathologic findings at CT urography include congenital abnormalities, filling defects, dilatation, narrowing, and deviations in course. studies that CT Urography (CT abdomen and pelvis without and with intravenous contrast) may not be warranted in specific patient cohorts, particularly young individuals without risk factors for urinary tract malignancy, who may be evaluated with a CT exam without contrast only (CT renal stone protocol).

Modern technology allows time‐resolved CT imaging (four‐dimensional CT excretory urography [4D‐CTEU]) over a distance exceeding the detector collimation. Friends I did Urography on 16 slice GE scanner and created 3d images with the help of reformat.

Over the past decade, computed tomographic (CT) urography has emerged as the primary imaging modality for evaluating the urinary tract in various clinical settings, including the initial workup of hematuria. With the widespread implementation of CT urography, it is critical for radiologists to under …. hybrid CT urography and a conventional CT urography with respect to their diagnostic accuracy and radiation dose has been lacking.
