"A variety of techniques have been described 1. A CTU may be performed along with other CT studies of the genitourinary tract, such as a 3 or 4 phase or split bolus study depending on departmental protocol2."
"10mg of IV furosemide may be given after this phase to improve excretory phase imaging"
"Non-contrast KUB to assess for renal calculi"
"Nephrogram or nephrogenic phase - timed series at 100 seconds, enhancement of renal parenchyma"
"Excretory phase to assess for renal collecting systems"
"Non-contrast KUB to assess for renal calculi"
Expected headings
"Purpose"
"The aim is to illustrate the collecting systems, ureters and bladder with intravenous contrast, albeit in a single acquisition as opposed to the multiple and more dynamic traditional IVU. Visualisation of other structures in the abdomen is also better with CTU than with traditional IVU. Upper tract tumours, strictures and to a degree the function of the kidney can be assessed."
