The most effective screening study of the genitourinary system is today recognized as computed tomography. This technique allows not only to reveal the slightest pathological changes, but also to precisely establish their localization. Computed tomography of the kidneys is indispensable in case of suspicion of the formation of tumors in the tissues of these paired organs, and also greatly facilitates the diagnosis of other diseases.
Why do multispiral computed tomography of the kidneys without contrasting and with the introduction of contrast media?
First of all, the described study provides the most accurate information about the functional state and functioning of the kidneys, the presence of congenital anomalies of their development.
The main indications for the appointment of CT:
- abscess;
- single or multiple cysts ;
- benign, malignant neoplasms;
- urolithiasis ;
- kidney trauma;
- inflammatory, infectious processes.
The procedure can be performed with the introduction of a contrast medium containing iodine, and without it. The first option is more preferable, since contrasting allows you to get maximum information about the blood supply to the kidneys, small and vascular structures of the organs, the formation and release of urine, the functioning of the cup-and-pelvic complex.
Preparation for computed tomography of kidneys and its implementation
The procedure in question does not require special preliminary measures. Only with the introduction of contrast agent, the expert will give instructions on how to prepare for computed tomography of the kidneys - it will be necessary to completely refuse to eat food 2.5-3 hours before the session.
Otherwise, the study is similar to other types of CT, during the procedure the patient takes off all metal objects and jewelry, is located on a horizontal moving surface. Inside the scanner, only the area to be inspected is located. The duration of the tomography is up to 20 minutes.
