Why do you need to hold your urine during a gynecological examination?

Gynecological diseases have become a major disease that endangers married women. The current environmental pressure has caused many women to be in a sub-healthy state. The long-term vicious cycle has caused gynecological diseases. In fact, some spots on the face or a bad complexion are all caused by gynecological diseases. So when conducting various gynecological examinations, you usually need to hold your urine. Do you know why you need to hold your urine during a gynecological 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, and are 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. 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.

Before doing a B-ultrasound, be sure to empty your bowels and bladder in the morning. Drink about 1000 ml of water before the examination and wait for about 1 hour. The examination can be carried out only when the patient has a very obvious urge to urinate. For emergency patients or those who cannot hold their urine, 500 ml of sterile saline can be injected into the bladder through a urinary catheter. Holding urine increases the pressure in the bladder and affects the normal regular urination function. Holding urine frequently can easily lead to cystitis or even bladder rupture. However, during B-ultrasound examination, holding urine is short-term and accidental, and usually does not cause harm to the patient. The patient should just try not to walk around when holding urine to prevent accidents caused by external forces such as collisions.

With the updating and improvement of instruments, we now have transvaginal B-ultrasound examination, that is, intracavitary ultrasound probe examination, which greatly facilitates patients, especially for patients in emergency or suffering from various diseases that are not suitable for holding urine.

The above is a detailed explanation of why you need to hold your urine during a gynecological examination. Usually, B-ultrasound examination is used. In order to enhance the results of the examination, you usually hold your urine. Drink more water before the examination, which will make holding your urine more effective. In order to ensure your own health, it is recommended that everyone, especially women, go to the hospital for regular check-ups.
