What is and how to perform transrectal ultrasound of the prostate?
Ultrasound of the prostate allows a detailed analysis of the problem. Unlike x-rays, this method is not encumbered by ionizing radiation. The study takes place in real time, and the current procedure helps to analyze the internal structure, and to determine the possible cause of the impaired blood flow in the prostate. Transrectal ultrasound of the prostate helps to consider the studied and surrounding parts. The essence of this method consists in the following: in the rectum are small ultrasonic sensor that starts to actively send the sound waves at different frequency, they are reflected from the walls of the prostate, which is in front of the rectum.
The main objectives of this research are:
- Diagnosis of prostate diseases.
- Detection of problems associated with increasing size and determine the optimal size. The received data may require during the treatment.
- Diagnosis of benign or malignant tumors.
- Assistance in determining causes of infertility.
In addition, ultrasound of the prostate allows to explore the basic symptoms which may cause negative changes.
It is necessary to include:
- The nodes that can be detected by a physician during the preventive examination of the patient.
- The increase in certain blood counts.
- Violation of urination.
Ultrasound of the prostate takes place in real time. Doctors can use this research method in the course of biopsy. The essence of this method is that the sample is taken a small amount of tissue and produced a detailed survey.
How should I prepare?
Ultrasound is a method that requires maximum relaxation of the patient. He needs to attend to the procedure in loose clothing. With the area to be exposed to sound research, it is recommended to remove all jewelry and the clothes. The doctor may give the patient a gown or shirt. If your doctor has prescribed a biopsy, the patient should abandon the use of those drugs that can thin the blood. Order ultrasound of the prostate and fast-before the procedure it is necessary to clean the rectum.The principle of operation resemblessonar system that is actively used by bats. Low-frequency sound wave is launched toward a particular object, then it is reflected and begins to form on the monitor of the apparatus of a distinct picture.
The length and nature of the waves can be adjusted depending on the purpose of the study. The resulting sound waves are recorded to monitor doctor. They are constantly measured.
This is done in order to have a real time to reflect the current state of the studied tissue structure or organ. In addition to periodically changing pictures, the doctor can make a small video fragment on the basis of which one can draw conclusions also in real time. The principle of operation of sensors that are introduced into the rectum, no different from the standard exterior treatments. Changing only the configuration of the device and all the functionality remains unchanged.
What can you see?
During the procedure, the doctor can observe the capsule of the prostate. Integrity safe is very important as it helps to diagnose prostate cancer. In most cases, the malignancy begins to grow outside the neurovascular bundles. In the process of ultrasound examination increases the likelihood of diagnosis and visualization of threat zones. In addition, the procedure time can be measured symmetry of the prostate, the geometry of the capsule and its internal structure.
Ultrasound helps to study the internal state giperplaziei areas, and it is very helpful in the diagnosis of BPH. It is possible to perform not only those boundaries that are violated in the spread of tumor formation, but also to pay attention to the internal structure. During analysis you can determine with almost 100% probability of the current stage of the adenoma. This can help in predicting the treatment and determining the most effective treatment. Ultrasound helps to differentiate stones in the prostate gland. Using modern equipment it is possible to observe the state of the ejaculatory duct flow - specific channels, which moves the seed. At a deeper introduction of the sensor it is possible to observe the condition of the seminal vesicles.
Timely diagnosis will accelerate the healing process and to minimize the negative effects.
