Topic of ultrasonic health science articles

Nowadays, many people have the experience of going to the hospital for ultrasound examination. You take the application form to the ultrasound triage desk, and the triage staff will tell you that there is a project that needs to pee. At this time, you said that I had just finished peeing in the toilet.

At the entrance of the ultrasound clinic, such a scene often appears. A patient was clutching his stomach and looked very uncomfortable. He said to the same patient next to him, "Comrade, can we change the number? I really can't hold it anymore. . . . . . "

Yes, it is necessary to prepare conditions before doing some ultrasound examinations, that is, to prepare patients, and holding urine is a requirement, so let's talk about holding urine today.

1, which items need to pee?

Abdominal examination: lower ureter, bladder, prostate, uterus and its accessories, early pregnancy (ultrasound examination of obstetric fetus less than 3 months pregnant), if placenta previa is suspected, the length of cervical canal should be observed and the bladder should be filled.

2. Why do you need to hold your urine?

Lower ureter, bladder, prostate, uterus and its accessories, uterus in early pregnancy, etc. Living deep in the pelvic cavity, the small intestine will also sag into the pelvic cavity. The peristalsis of the intestine and its contents will interfere with the ultrasonic image, resulting in unclear image display. Bladder filling can push the intestine upward and help to show its structure.

If the bladder is not full, there may be intestinal gas interference, and the gas in the bladder will overlap with the uterus, resulting in misdiagnosis or missed diagnosis.

However, not all gynecological transabdominal ultrasound examinations need to hold urine. After pregnancy 12 weeks, the uterus is enlarged, the intestinal tube is naturally pushed open, and there is amniotic fluid in the uterine cavity. You don't need to hold your urine at this time.

3. How to urinate quickly?

There are many ways to hold your urine quickly:

The first method is to drink plenty of water, drink plenty of water and walk properly, so that you can hold your urine quickly, but this situation does not mean that you can reach the bladder immediately after drinking water. You know, it takes a tortuous process for food and drink to be absorbed through the gastrointestinal tract of the human body, then to the blood circulation and then to the kidneys to form urine. All the water you drink takes a while to form urine.

The second method is to drink diuretic drinks such as tea and coffee, as well as watermelon juice and strawberry juice. At the same time, drink more white water, with standing exercise, the effect of holding urine is better.

The third method is oral or injection of diuretics, which can generally fill the bladder in 20 minutes. Of course, you need to find a clinician to prescribe medicine for you.

4. To what extent do you need to suppress it? The more urine you hold back, the better?

Anyone who has had an ultrasound examination that requires urination should have had this experience: after drinking half a bucket of water for two hours, the doctor said that the urine was insufficient and continued to drink. In an emergency, it won't be your turn for a while. At this time, many people are afraid to go to the toilet to drain some water first, saying that urinating is not to turn on the tap, but to turn it on and off if you want.

However, the more urine you hold, the better. Generally speaking, it is best to hold your urine until you feel it. This is not like many people's "rumors", it is best to suppress urine to the limit, because an overfilled bladder will oppress pelvic organs and make them shift and deform, and some subtle lesions, such as uterine fibroids and ovarian cysts, are often covered up. Signs of pregnancy (gestational sac, embryo) are also not clearly displayed because they are compressed and flattened. Therefore, holding the urine, like Otawa holding the urine too little, will cause difficulties and mistakes in diagnosis.

Doctors suggest that in order to avoid the above-mentioned "urine-holding dilemma", urine volume can be controlled by drinking water and holding urine for a long time.

To do gynecological ultrasound, the bladder urine volume is required to be 300- 400m l, and 500-800 ml of water should be drunk before examination. Generally, you need to hold your urine for 2 hours and drink 800- 1000 ml of water, and you need to hold your urine 1 hour.

So how can we calculate the appropriate urine volume?

The sign of good filling is that when the subject lies on his back, the lower abdomen slightly bulges in a shallow arc, and can sink and tolerate when pressurized.

If the abdomen bulges high and the abdomen is hard, it will be unbearable to exert a little force, that is, there is too much urine and too much filling.
