CT cystography is a variation of the traditional fluoroscopic cystogram. Instead of anterograde opacification of the urinary collecting system (as with CT urography), contrast is instilled retrograde into the patient’s bladder, and then the pelvis is imaged with CT.
What is the current role of CT urography?
CT urography provides a detailed anatomic depiction of each of the major portions of the urinary tract–the kidneys, intrarenal collecting systems, ureters, and bladder–and thus allows patients with hematuria to be evaluated comprehensively.
