How many months pregnant do you need to hold your urine when doing ultrasound?

When I went for an ultrasound after I became pregnant, the doctor always reminded me to drink plenty of water and hold my urine. Therefore, many new mothers ask questions in these areas. Although they have read a lot of relevant content, many people still feel doubtful. So, do you need to hold your urine when doing an ultrasound in the early stages of pregnancy? How many months into your pregnancy do you no longer need to hold your urine when doing an ultrasound? Next, let us talk about it in detail.

Do I need to hold my urine during an ultrasound in early pregnancy?

There are two types of gynecological B-ultrasounds, one is abdominal B-ultrasound, and the other is vaginal B-ultrasound. You need to hold your urine for abdominal B-ultrasound because it can only see our uterus and ovaries through the bladder. After the bladder is inflated, abdominal B-ultrasound can show more clearly, but its accuracy is lower than that of intravaginal B-ultrasound. Intravaginal B-ultrasound is directly inserted into the vagina and is not likely to affect the bladder, so there is no need to hold urine. From an anatomical point of view, the uterus and appendages are located in the pelvis, with the bladder in front, the duodenum behind, and the intestines around. If the bladder is not full, there is a lot of gas behind the uterus and appendages hidden in the pelvis, and ultrasound cannot easily pass through the gas. Therefore, the doctor cannot clearly see the uterus and appendages behind the bladder on the screen. All he can see are the reflected surface waves of the gas and the echo of the intestine. When the bladder is full, the surrounding air is expelled, and ultrasound passes through the urine stored in the bladder, and a clear image of the uterus and appendages is displayed on the screen. This shows that a full bladder can sometimes be a good assistant to the doctor. Therefore, during B-ultrasound examination, you must hold your urine before doing an ultrasound examination of the uterus and appendages, but you do not need to hold your urine when using an intravaginal camera.

You need to hold your urine when doing an ultrasound in the third month of pregnancy. The main reason is that the uterus is still in the pelvis. In order to have a clearer image, you need to hold your urine to fill the bladder, so that a "perspective window" can be formed through the bladder to observe the fetus.

How many months pregnant do you need to hold your urine when taking an ultrasound?

Ultrasound examinations of pregnancy are usually very short, lasting only a few minutes, and generally do not affect the fetus in the late gestational age of the uterus. Generally speaking, 3 to 4 ultrasound examinations during pregnancy are sufficient. Pregnant women generally do not need to fast when doing B-ultrasound, and eating before B-ultrasound will not affect the data. In addition, if it is an ultrasound examination in the early stages of pregnancy, you need to hold your urine in advance and accumulate a certain amount of urine in the bladder so that you can see it clearly. In the middle and late stages of pregnancy, you don't need to hold your urine to do an ultrasound.

You don't need to hold your urine when doing an ultrasound three months into your pregnancy. This is mainly because the uterus is getting bigger and bigger, exceeding the range of the bladder. In addition, the amniotic fluid flow is increasing, and a "window" is formed in the amniotic fluid of pregnant women. Therefore, you no longer need to hold your urine to observe the intrauterine condition of the fetus.

So is it necessary to hold urine during the third month of pregnancy? Generally, when pregnant mothers go to the hospital for a B-ultrasound, some B-ultrasound technicians will ask them to hold urine, while some do not. In fact, whether or not to hold urine during the third month of pregnancy varies from person to person. It is recommended to follow the doctor's advice.
