CTU stands for Computed tomography urography, a medical imaging abbreviation.
Multiphase CT of the kidneys, ureters and bladder that includes a delayed excretory phase after contrast fills the urinary tract. It is the standard imaging test for visible blood in the urine, detecting stones, kidney tumors and urothelial cancers of the collecting system and ureters.
Example: CTU for gross hematuria: filling defect in the left renal pelvis.
Usage notes
CTU replaced the intravenous pyelogram in most centers. A split-bolus technique combines two contrast phases into one acquisition to lower radiation dose. MR urography is an alternative for pregnant patients and those who cannot receive iodinated contrast.
