Should I have an empty stomach or hold my urine before B-ultrasound examination? See what the experts say.

When we go to the hospital for examination, it is inevitable to have a B-ultrasound examination. Some tests need to urinate, some tests need to be on an empty stomach, and patients are almost all confused. So in order to make everyone better prepared before seeing a doctor, this time we will talk about whether it is fasting or urinating before B-ultrasound examination.

Fasting is needed to check the liver and gallbladder.

If you do an ultrasound examination of the upper abdomen, it is mostly a hepatobiliary examination. You can't eat for 8 hours before the examination, and you can't drink water for 6 hours. The reason for this is to make the gallbladder full, and the gallbladder is full of bile on an empty stomach, which is convenient for examination; If you eat it, it will enlarge the gastrointestinal tract and contract the gallbladder, which will affect the doctor's observation and lead to misdiagnosis.

Check the urine and hold it.

If the urinary system such as bladder and ureter is examined by ultrasound, or the uterine adnexa and prostate are examined by ultrasound, a large amount of water is needed before the examination to hold the urine. Because these organs can only be observed by ultrasound in the filling state, otherwise the ultrasound image is difficult to distinguish and will be misdiagnosed.

Ask how many people in front.

I often encounter the number, and the result is that I can't hold my urine, or I can't hold my urine and can't wait for myself. In order to avoid this situation, you can drink a cup of 300 ml water at home, bring a bottle of 600 ml water, and ask how many people are in front when you hand in the list, so that you can know when to drink the rest of the water.

Drink water 45 minutes in advance

Generally speaking, it will be in front of you in 45 minutes. At this time, you can finish drinking 600 ml of water, and when it's your turn to check, the urine in your bladder is almost ready. Of course, everyone's water consumption and urine production speed are different. Everyone still needs to combine their own situation and summarize it every time to facilitate future inspections.

In addition, for women, it is necessary to hold their urine for abdominal B-ultrasound examination. Now there is vaginal B-ultrasound examination, which has the advantage of not holding their urine and presenting a clear picture, but people who have no sexual history cannot do vaginal B-ultrasound examination.
