Jul 16, 2024 · 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. It gives both anatomical and functional information, albeit with a relatively higher dose of radiation.

Jul 16, 2024 · Intravenous urography (IVU) is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and urinary bladder using intravenous contrast medium. This exam has been largely replaced by CT urography.

A good example of a normal CT-IVU study. The chief indication is for the assessment of hematuria.

Mar 23, 2023 · Computed tomography of kidneys, ureters and bladder (CT KUB) is a quick non-invasive technique for diagnosis of urolithiasis. It is usually considered the initial imaging modality for suspected urolithiasis in an emergency setting 1 .

Mar 3, 2025 · Fluoroscopy/IVU Traditionally intravenous urography/pyelography (IVU/IVP) has been performed for assessing for pelviureteric junction obstruction. The administration of furosemide may be used to assist in confirming the diagnosis, in particular, to exclude a dilated non-obstructed upper collecting system (so-called ' baggy pelvis ').

Sep 27, 2023 · CT. CT with intravenous contrast and delayed scan with full reformatted sagittal and coronal images and 3D reconstruction. The delayed scan should be performed between 5-8 minutes after IV contrast to ensure a CT-IVU (a.k.a. excretory phase) set of images is acquired. Features include 5: intra-abdominal fluid collections without other cause shown

Mar 23, 2025 · There is usually no need for a three or four phase CT IVP (CT urography). A single 45-90 second post-contrast scan usually suffices, although clinical acumen may be necessary to choose the best contrast phase 2,7 .

Excretory phase CT ( CT-IVU) illustrated excellently a fistulous tract between the vagina and bladder in keeping with a vesicovaginal fistula. In this case this is likely to be post operative/iatrogenic in nature, given the low stage pelvic malignancy prior to hysterectomy.

Nov 24, 2024 · Intravenous urography (IVU) is a traditional radiographic study of the renal parenchyma, pelvicalyceal system, ureters, and the urinary bladder. It involves the administration of intravenous contrast. This exam has been replaced mainly by non-contrast CT. Ultrasound

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.
