CT Urography
What is the purpose of a CT Urography?
This examination replaces the earlier so-called intravenous urography and is used for the examination of the urological organs - the kidneys, the ureter and the bladder. These organs may be examined individually, but, combining them with the abdominal and pelvic CT examinations, allows us to obtain precise information about even more organs.
Congenital, inflammatory and tumorous organ abnormalities may be shown with this method and kidney, ureteric and bladder stones as well as any secondary changes resulting from other organs. The cause and location of the flow's obstruction may be pinpointed, the dilatation of the kidney chambers as well as the dilatation and continuity of the ureters may be shown along with the bladder.
Are there any necessary preparations prior to the appointment?
No special preparation is required other than that you not ingest any food before your appointment. An empty stomach is required. Certain diabetic medications are not compatible with the contrast material and should not be taken. It is important, in this case, that you consult with your doctor beforehand.
What happens during the procedure?
When only a urography is required, a series of regular CT images is done. Following the administration of a contrast material, a series of either single or multiphase images is prepared and, after a short waiting period, an excretory urography.
Should the urography be combined with an abdominal-pelvic examination, the Patient will be required to drink a liquid for one and a half hours prior to the examination following which the image series described above will be prepared.
Subsequently, a series of thinner slices will be prepared from which 2D and 3D images will be gained with the help of a special software.
Contraindications
Allergic reaction to the contrast material.
