Why do you hold your urine when doing uterine ultrasound?

When women go for gynecological examinations, they usually use instruments such as uterine color ultrasound to determine diseases or other conditions. At this time, you will usually be told to hold your urine in advance, otherwise the examination cannot be carried out. So why do you need to hold your urine? The editor has collected detailed information and found the answer. Please read the following content to find out.

The uterus and ovaries are located deep inside the pelvic cavity, and the small intestine tends to hang down into the pelvic cavity. When performing an abdominal B-ultrasound, the peristalsis of the intestines and their contents will interfere with the image of the uterus and ovaries, causing them to appear unclear. Therefore, you need to drink plenty of water before the examination to fill your bladder and push your intestines upward. 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. However, not all gynecological transabdominal B-ultrasounds require holding urine. It is not necessary in the following situations: After 8 weeks of pregnancy, the uterus grows and rises into the abdominal cavity, pushing the intestines naturally upwards. There is amniotic fluid in the uterine cavity, so there is no need to hold urine to observe the fetus.

You need to drink about 6 to 8 cups of water half an hour to one hour before the examination. Generally speaking, it is best to hold your urine until you feel the urge to urinate. This is not like what many people "rumor" say, that you need to hold your urine to the limit, because an overfull bladder will compress the pelvic organs, causing them to shift and deform, and some subtle lesions are often covered up, such as small uterine fibroids, ovarian cysts, etc., which will not be shown. The signs of pregnancy (gestational sac, embryo) are also not clear due to being flattened by pressure. Therefore, holding urine for too long, just like holding urine for too little, can cause diagnostic difficulties and errors.

I believe that after reading this, female friends will know the specific reasons. Then, when preparing for a check-up in the future, you can drink more boiled water in advance to avoid wasting time. In addition, the editor would like to make a reminder that you should never perform uterine color ultrasound examinations frequently in daily life, otherwise it may damage your health.
