How to hold urine quickly for color Doppler ultrasound

Color Doppler ultrasound is a physical examination item that can detect human diseases. Usually people's urine is used for urine tests, and people are required to hold their urine. Humans cannot control urine, so holding urine requires certain scientific methods and strategies. Most people will feel nervous before doing a color ultrasound and easily feel the urge to urinate. So how can you hold your urine quickly before doing a color ultrasound?

Method 1: Make preparations

If you know you are going to have an ultrasound, you should drink 300 ml of water before going to the hospital, and then drink it slowly after arriving at the hospital according to the situation on site.

Method 2: Drinking water in small sips can help you urinate faster

When some people hear that they are going to have an ultrasound, they drink a lot of water, pouring it down their stomachs in big gulps. In fact, this will slow down the production of urine.

Because the swallowing action is fast, the water you drink reaches the colon quickly and is absorbed by the stool there (the stool absorbs water and becomes soft). Therefore, part of the water you drink is excreted with the stool.

When you drink water in small sips, the water flows slowly and is easily absorbed by the small intestine into the blood, and finally forms urine and is stored in the bladder. In this way, urine is produced faster.

Drinking small sips of water while walking can speed up urine production.

Method 3: Drink sugar water

If you consume more sugar, the osmotic pressure of the blood will increase, the permeability of the blood vessel walls will increase, and the kidneys will produce more urine, so hyperosmotic sugar has a diuretic effect. Therefore, before the B-ultrasound, you can drink some honey water, sugar water and other beverages, or you can drink watermelon juice, apple juice, etc. to promote urine production.

3. It’s not okay to hold your urine for too long!

It should be noted that the more you hold your urine, the better. Otherwise, it may affect the results of the B-ultrasound examination.

An overfilled bladder can compress the pelvic organs, causing them to shift and deform. Some subtle lesions can be easily concealed, such as small uterine fibroids, ovarian cysts, etc. Signs of pregnancy (gestational sac, embryo) can also become flattened due to pressure and become unclear.

4. What are the signs that urine retention has stopped?

The sign of a well-filled bladder is that when the subject lies flat, the lower abdomen is slightly raised in a shallow arc shape, which sinks when pressure is applied and is tolerable.

If the lower abdomen is sunken and lower than the anterior superior iliac spines on both sides, it is insufficiently filled;

If the abdomen is bulging very high, the belly is very hard, and a little pressure is unbearable, it is overfilling.
