Nasal vasodilation of the kidney: the rules for the preparation and conduct of the study
UZDG of kidney vessels is formed on the basis of the Doppler effect. This method allows to investigate the diameter and rapidity of blood flow of renal vessels, their localization, and also to consider the location of arteries and veins relative to the kidney.
The ultrasound dopplerography of renal vessels should be understood as the process of reflection of ultrasonic waves from blood-moving red blood cells. Further, the ultrasonic sensor, the reflected waves are converted into electrical pulses, which can be seen on the monitor in the present mode in the form of photographs and graphs. They can observe the process of blood flow through the blood vessels. Thanks UZDG specialist can observe the vessels "from the inside".
UZDG kidney vessels allows:
- to detect damage to the circulatory system of the kidneys;
- establish the blood flow velocity in renal vessels;
- identify early disturbances in vascular function, as well as changes triggered by atherosclerotic plaques and thrombi;
- reveal the presence of arterial stenosis, as well as its role( since this is one of the causes of hypertension).
Also, ultrasound Doppler ultrasound can evaluate the effectiveness of the prescribed treatment and establish indications for the surgical intervention.
Preparation for ultrasound of renal vessels
A good and correct preparation for the study is very important, because the accumulation of intestinal gases complicates the visualization that affects the outcome of the study. Therefore, to make a picture of quality, 2-3 days before the scheduled research, some foods from the diet should be removed( legumes, fruits and vegetables, cabbage, sweets, drinks with gas, black bread and juices).And also with an increased predisposition to gassing, you should drink enterosorbents( espumizane or activated charcoal 2 tablets 3 times a day) for 2-3 days.
Performed ultrasound of kidney vessels on an empty stomach in the morning. If the study is scheduled for the afternoon, a light breakfast is allowed in the morning.
It is very important to remember that carrying out ultrasound after colonoscopy or fibrogastroscopy does not make sense, because as these studies penetrate the air into the intestines, and this leads to difficulties in visualization.
The study is as follows:
- Before the start of the study, one should undress to the waist, jewelery is removed from the examination area. Then the patient is lying down. On the area to be investigated, a transparent gel is applied, which allows close contact between the ultrasound and skin sensor.
- The research data is entered into the electronic database, and the patient is given a copy, as well as images with detected changes.
- This study lasts no more than 30 minutes and passes painlessly.
Decoding of the results of
After the ultrasound of the kidney vessels, the result is immediately given to the patient. The deciphering of ultrasound is performed by a specialist. Although the final diagnosis is made by the attending physician.
Positive aspects of the USD:
- The majority of ultrasound is performed by a non-invasive method, and is painless( without injections);
- is generally available, inexpensive compared to other methods of visualization;
- no ionizing radiation;
- this method of ultrasound examination is performed in the present time;
- with the help of this method, it is possible to get a clear picture of soft tissues( which can not be obtained by radiography).
Is there any risk during dopplerography of kidney vessels?
If we talk about the standard diagnostic ultrasound factors that indicate the likelihood of adverse effects on humans have not been identified. Information on the limitations of UDDG renal vessels
Ultrasonic waves are a universal tool that is used to diagnose various vascular lesions, but it can not completely replace studies such as renal angiography, which provides a more accurate representation for confirmation or denial of the diagnosis.
