Doplerografia - one word can scare people, unfamiliar with medicine. Probably something very complex, scientific and generally incomprehensible. But in fact, almost every motorist encountered with this method of research. Let us remember: it's completely empty road, the foot presses the gas pedal as usual, taking the speed of the machine in an area that never dreamed of traffic police inspector, and suddenly a shrill whistle and wave a "magic wand" and the testimony of an unforgiving "spidgana. Purse become easier, but the mood worse. So, just using Doppler was recorded your speed. In humans, too, there are objects that can move with the "inadmissible" speed. In order that would "catch" violators and to identify the main reason for such a violation is used in medicine doplerografia.
The velocity of the heart valves, the intensity of cerebral blood flow, blood flow in the vessels of the limbs, - all this can be studied using Doppler. In urological practice, most Doppler is used to diagnose kidney disease. The fact that this pair has an amazing body vascular system. In the kidney takes place 1 / 5 of blood ejected heart. In one gram of mass have a greater volume than even the brain. And if we consider that any disease inevitably affects the blood supply for the body, it turns out that Doppler - a method that can detect the earliest signs of changes in the kidneys. Moreover, the study not only speed, but also other parameters of blood flow: vascular resistance, pulse. But if doplerografia gave only dry numbers, it would not be so interesting. The fact is that modern devices that can place the image on vascular ultrasound image. It turns out that the urologist can not only know the characteristics of the vessel, but to see him.
How is doplerografy study? Initially, with conventional ultrasound, appears on the screen image buds included Doppler mode, and now a gray-black picture pulsates red arteries, blue - a vein. And in order to obtain an image of a vascular network does not need to enter the patient a contrast agent, to irradiate X-rays.
What tasks can solve doppler study? First of all, this diagnosis. Imagine that in the kidney revealed incomprehensible surround education includes doppler, and it becomes clear that there are no blood vessels, and therefore most likely a cyst. Another thing, if in the center of education shows many irregularly arranged vessels with clearly impaired performance. In this case, the tumor is suspected, and a survey will go a completely different course.
Often difficult to understand when the kidney is reduced in size: it is - a congenital anomaly or contracted kidney? Doplerography allows you to see and "calculate" renal vessels, if blood flow properly developed, but severely reduced, and the resistance high, there is every reason to believe that this is a contracted kidney, which must be removed.
Many of the girls that are consistent with the model representations of the beautiful, suffering kidney prolapse, or Nephroptosis. Deficiencies in fatty tissue deprives these organs of support, the kidney become mobile with breathing. This kidney "hangs" on the renal artery, which, pulling sharply reduced in diameter. It is difficult to assess how disturbed blood flow, needed immediate surgery or you can do with exercise therapy. When such a patient comes to the Doppler, it is sufficient to measure the parameters of blood flow in the renal artery, lying down, standing up and costs involved, to evaluate the differences and decide on further treatment. Since Doppler has become one of the most important diagnostic omissions kidneys.
But the diagnosis is established, planned operation. Using doppler surgeon can always advance to see how the tumor is located, whether it is far from the renal artery, which is adjacent to the formation of blood vessels and to choose the best type of operation.
Doppler unit installed in the operating room, can provide substantial assistance during surgery. Because the patient does not need specially trained to study. Special sterile probe, immersed in the wound, would circumvent the major blood vessels, to determine the depth distribution and especially the location of the tumor.
When the surgery is over and the patient is in intensive care, the only way to assess renal blood flow is Doppler, because this method has no effect, and therefore can not cause complications for the patient in a dangerous period.
In the past year in one of the urological journals has been described by a unique operation. Tumor of the kidney was located only directly in the center body. Surgeons had to cut the kidney almost in half, remove the malignant tumor, and then sew the kidney. Postoperatively, renal blood flow was monitored using Doppler. This could be seen as a bud, literally comes alive ", and more took place days after a difficult intervention, the more intense become the renal blood flow. With the Doppler technique was to obtain information that will allow the plan such complicated operations.
Of course, not only renal blood flow can be studied using doppler.
In the male health center used doppler study of the prostate gland. Chronic prostatitis, hyperplasia (adenoma) or prostate cancer often require conservative treatment. But many drugs act differently on different people. In order to select the optimal drug and dosage, with the help of Doppler estimated reduction in foci of pathological blood flow during drug treatment. At the end of treatment in the same way you can evaluate the effectiveness of various drugs.
It happens that the patient comes to a urologist at the stage when only using the operation can save him from an adenoma or cancer. In this case, Doppler will help you choose the best method of surgical treatment, the method which enables to perform the operation with the least risk to the patient.
We can not tell you about another doppler study, to which many representatives of the strong half of humanity would have gone to troubling doubts. There is a method for measuring the velocity of blood flow in the vessels of the penis. This means that the urologist armed doplerografy technology can very accurately determine the cause of violations of potency. And when the clear origin of the disease, we can choose the necessary treatment and using the same "doppler" to check its effectiveness. This usually happens this way: the penis is explored in "quiet" state, then with the help of medicinal drugs cause an erection, and doppler is performed repeatedly. By comparing the results of these two studies can be understood that hampers the normal functioning of the "harmonizer" of family relations.
