How to do color Doppler ultrasound without holding urine

Color ultrasound is a common examination method. When doing color ultrasound, the requirements will be different depending on the examination site. For example, when a woman is doing a gynecological B-ultrasound examination, she needs to hold her urine for an abdominal B-ultrasound, but she does not need to hold her urine if she is doing a vaginal B-ultrasound. In addition, pregnant women do not need to hold their urine when doing abdominal B-ultrasound. Let's see how to do color ultrasound without holding urine.

Some gynecological B-ultrasound examinations require you to hold your urine, while others do not. B-ultrasound examinations can be divided into two types: one is abdominal B-ultrasound examination, and the other is vaginal B-ultrasound examination. Abdominal B-ultrasound examination requires holding urine. There is no need to hold urine during vaginal B-ultrasound examination.

Why do you need to hold your urine when doing color Doppler ultrasound?

Holding urine is necessary to provide a good viewing window for ultrasound examination. Because in the human body's physiological structure, the uterus and its appendages are located in the center of the small pelvis, between the bladder and the rectum, in an anteriorly tilted and anteflexed position, and ultrasound has different echoes for solid, liquid and gas-containing tissues. When the bladder is full, there is a dark area of ​​fluid on the sonogram. The uterus is a solid organ with a cavity, as seen on the sonogram.

The normal uterus is located behind the dark area of ​​the bladder, and the uterine wall is a solid dark area. During ultrasound examination, when the ultrasonic beam enters the body and encounters gas, it will form total reflection, that is, echo zone, and no image will be displayed on the screen. Ultrasound examination uses the echo-free area to form a sound-transmitting window, and then makes a diagnosis based on the different strengths of ultrasound reflection from different tissues in the body.

Therefore, if an ultrasound examination is performed when the bladder is not full, the gas in the bladder and the gas in the uterus will overlap, causing misdiagnosis or missed diagnosis. Therefore, ultrasound examinations often require patients to fast and hold their urine. This is a prerequisite for a successful examination and is very important.

What is the name of the color Doppler ultrasound that does not require holding urine? The editor mentioned above that there are examinations that require holding urine and those that do not require holding urine. If you want to go to the hospital for a check-up, the doctor will tell you whether you should hold your urine during the test. In fact, holding urine is for better and more accurate diagnosis of diseases. Patients should not be reluctant to go for a check-up because of embarrassment. After all, physical health is the most important thing.
