Computer tomography of the kidneys. Training, feedback
In order to prescribe an effective treatment for any disease, it is necessary to diagnose as accurately and correctly as possible. With modern methods of diagnosis, this is usually not very difficult. This is especially important in conditions that are dangerous for the patient's life. Diseases of the excretory system occur quite often. Without its normal operation, it is impossible to cleanse the body of harmful substances, so it is important to find the problem on time and get rid of it. The main method of diagnosis can be a computerized tomography of the kidneys, which will help to make an accurate diagnosis. We will get acquainted with this method of research in some detail.
The essence of tomography
This diagnostic procedure is based on the use of X-rays and the latest computer technology to obtain an image of the organ under investigation. If we compare this method with the X-ray, then we can state that CT is more informative.
During the investigation, the X-rays are moving around the body, and all changes about their energy are transmitted to the computer, which after the information conversion displays a two-dimensional image.
Tomography as a method of diagnosis began in the 20 th century. By now, the operating principle of the apparatus has changed. Now the following tomographs are distributed:
- SCT - spiral tomography. It gives an opportunity to investigate the layered structure of the body in a few seconds.
- Multi-spiral computed tomography of kidneys is practiced in clinics in Moscow and not only. A distinctive feature of such devices is the presence of several detectors, and the number of revolutions of the X-ray tube is also increased.
The study can be done with or without contrast medium. It is usually used in cases where it is necessary to obtain a clearer image of the organ under investigation.
What can be detected using CT
Kidney pathologies are serious enough diseases that require immediate intervention and effective treatment. Many states can not be recognized by conventional diagnostic procedures. Only after the computer tomography of the kidneys appeared, it became possible to diagnose such pathologies as:
- Congenital anomalies in the structure of the kidneys.
- Benign entities( eg, cyst).
- CT helps to identify problems with the excretory system even in newborn babies.
- Hydronephrosis at any stage of development.
- Cancerous tumors inside the kidneys.
- Pathological conditions caused by problems in the circulatory system, for example, renal infarction, thrombosis.
- Recognition of violations that occurred after trauma, surgical intervention.
All these deviations are easily determined by computed tomography, which allows an effective treatment to be scheduled in time.
Indications for CT
It is possible to check the functioning of the kidneys using many diagnostic methods. First of all, these are laboratory tests that will immediately show deviations from the norm. When visiting a urologist, the direction to the described study is not always given, but the treating physician will necessarily be assigned a CT scan of the kidneys if:
- The patient sustained a severe back injury.
- There is an infectious kidney disease in the chronic stage, which is accompanied by a malfunctioning organ.
- There are congenital anomalies in the development of the urinary system.
- There is a suspicion of having stones in the kidneys or the excretory pathways.
- All studies suggest that there is a tumor in the kidneys.
- There is a suspicion of having a cyst.
Computer tomography of the kidneys allows you to monitor the stages of development of tumors, which makes it possible to take the necessary measures in time.
Contraindications to CTD
Despite the fact that computed tomography is a completely painless procedure and does not pose a danger to humans, there are a number of contraindications for its conduct:
- Do not prescribe tomography to pregnant women, especially in the second half of the term.
- Breastfeeding is also not recommended for breastfeeding.
- If the doctor in the patient's card sees a history of thyroid problems, the diagnosis is "diabetes mellitus at a serious stage," then tomography is prohibited.
- Contraindications for the procedure are skin cancer.
- Relative contraindication - body weight over 120 kg.
- Without urgent need, do not do CT to children under 14 years of age.
- If the patient does not feel well before the procedure, it is better to postpone it at a more appropriate time.
All these contraindications are relative, therefore, if CT is the only way to make an accurate diagnosis, the procedure is appointed.
Many people have the question: where to make a computerized tomography of the kidneys? Most medical centers have all the necessary equipment for carrying out this procedure. For example, in Moscow it can be done in such centers as:
- The multidisciplinary medical center "Stolitsa".
- Clinic "Center of Endosurgery and Lithotripsy".
- MDC "Ramsey Diagnostics".
- Diagnostic Center "Clinic of Health" and many others.
How to prepare for the procedure?
If a computerized tomography of kidneys is prescribed, special preparation is not required. You can ask the doctor any questions that interest you in connection with the upcoming procedure.
If a contrast medium is to be used, the patient must sign a special consent form, having carefully read it beforehand. Before CT with contrast, it is advisable to refrain from eating for three hours before the procedure.
If there are various forms of allergy or other diseases and pathological conditions at the moment, this should also be reported to the doctor.
It is always possible to ask your doctor how to prepare for computed tomography of the kidneys.
If everything is ready, the questions are cleared up, then you can proceed with the procedure itself. It involves several steps:
- The patient must remove all metal objects from himself.
- A person should be in spacious clothes. If the patient does not have one, he is asked to wear a bathrobe.
- The examinee lies down on the table, which will move into the tomography ring.
- Control the device from the next room, but the patient is under full control.
- Computer tomography of the kidneys( photo shows it) involves the exclusion of any movements during the procedure. This distorts the image in the pictures.
- After the appropriate specialist team, the patient should hold his breath.
- When using a contrast medium, it is injected through the injector or drunk.
- Then the device turns on, and the tomograph ring starts to rotate around the patient. At this time, you can hear some sounds.
- The body "absorbs" X-rays, and this is fixed by the sensors of the device, and then the information is processed by the computer. The result is a picture that interests specialists.
- After completion of the procedure, the examinee waits for some time while the quality of the received pictures is studied. If they have a fuzzy image, then you have to repeat everything.
The time of the whole procedure is a few minutes, if without contrast. And up to half an hour, if a special substance was used.
After the procedure
Computer tomography of the kidneys reviews in most cases is good. Some patients note if a contrast agent was used, that itching, small swelling, or shortness of breath may occur. All this must be reported to the doctor. In the place of the IV infusion, pain can also be felt or redness may appear, but this quickly passes.
After completion of the procedure, special supervision is not required, the patient can lead a habitual way of life.
Possible complications during and after tomography
It is always possible to find out from the doctor what the radiation load is on the body during the procedure, and also about possible undesirable consequences. Usually complications associated with radiation appear and are dangerous if the patient passes a lot of studies related to radiation diagnostics.
In order for the fetus to develop normally, CT scans can not be performed during pregnancy. Necessarily the attending physician should know that the woman is in position.
The accuracy of the image during computed tomography is influenced by several factors:
- Metal objects in the abdominal organs, for example, surgical clamps. It is necessary to report this to a specialist.
- Radiography using barium before CT.
- There have been recent studies using contrasting or other substances.
All this is preliminarily discussed with a doctor and a specialist who conducts a tomography scan, and the question is decided on an individual basis in each case.
results As soon as the computerized tomography of the kidneys is completed, the specialist will evaluate the results. A full imprisonment usually takes about 1.5 hours. It is possible to record the results on a disk and give it to the patient.
It is clear that everyone will have their own result - who have completely healthy organs, and who has some pathologies. Based on computed tomography, the attending physician can prescribe adequate treatment, which will give positive results.
For effective treatment of any disease it is very important not only on time, but also accurately diagnose. Computer tomography provides an excellent opportunity to do this quickly and safely for the patient. Do not be afraid of such procedures, it is better to identify all problems in time and solve them. Take care of yourself and your health!
