Computed tomography of the kidneys
Computed tomography of the kidneys is a type of X-ray examination of the kidneys by scanning them layer by layer and converting them into an image. CT is a traditional, safe and one of the most common methods for diagnosing kidney disease.
Possibilities of CT of the kidneys
Computed tomography is a modern method of radiation diagnostics of a person, with the help of which it is possible to obtain an image of the finest sections of the kidneys. This study is highly informative. It is used in urology to detect pathological changes in the structure, location and functioning of the kidneys. With the help of CT, it is possible to easily diagnose space-occupying lesions, cancerous tumors, and small calculi that are hardly detected during an overview urography.
Kidney CT indications:
- urolithiasis disease;
- kidney injury;
- inflammatory processes of the genitourinary organs;
- preparation for kidney surgery, taking tissue fragments for histological examination;
- polycystic ;
- congenital anomalies of the ureters and kidneys;
- search for metastases in the retroperitoneal space;
- kidney tumors;
- upcoming surgery for kidney transplant;
- damage to the lymph nodes of the retroperitoneal region.
Contraindications for CT of the kidneys:
- decompensated stage of diabetes mellitus;
- renal failure;
- allergic reactions to iodide compounds;
- pregnancy and lactation period.
For better visualization of the parenchyma, pelvis and ureters, X-ray contrast agents are used during computed tomography.
In the absence of contraindications, CT in most cases is performed using contrast agents. The drug enters the vein, is distributed in the tissues, and after a while is completely excreted in the urine. Contrasting images allow you to study in detail the structures of the kidneys and their functionality.
Preparing for CT of the kidneys
CT without the use of contrast does not require preparation from the patient. If the doctor decided to use contrast enhancement, then 4-6 hours before the procedure, the patient should not eat food. All metal objects falling into the scanned area must be removed by the patient during the study period.
