Do I need to hold my urine during the 4D test during pregnancy?

The best time to check four-dimensional color ultrasound for single pregnancy is between 23 and 27 weeks of pregnancy, and for twins is between 22 and 23 weeks. Because the fetal structure at this stage has already formed, the baby's size and the amniotic fluid of the pregnant woman are moderate. Do you need to hold your urine when doing four-dimensional color ultrasound? Let’s have a simple understanding of this issue below. I hope the following points will be helpful to everyone!

Do I need to hold my urine when doing 4D color Doppler ultrasound?

This is an issue that many pregnant women are concerned about. In the past, you had to hold your urine when doing a B-ultrasound, but whether you need to hold your urine when doing a four-dimensional color ultrasound depends on the number of weeks of pregnancy. You need to hold your urine when the number of weeks is young, but you no longer need to hold your urine as the number of weeks increases. Generally, you no longer need to hold your urine when doing a four-dimensional color ultrasound after four months of pregnancy.

The basic principles of four-dimensional color ultrasound are similar to those of general B-ultrasound. Pregnant mothers can eat something and drink a few drops of water thirty minutes before doing the four-dimensional color ultrasound, which can increase the baby's fetal movement.

Common problems for pregnant women doing 4D color Doppler ultrasound

1. Pay attention to the time when doing 4D color Doppler ultrasound

Generally speaking, the best time for pregnant women to have a four-dimensional color ultrasound is during the fifth to sixth month of pregnancy. Because at this time, the fetus is in the stage of rapid brain development. The fetal structure has been formed, the activity space in the uterine cavity is relatively large, the echo effect of the fetal bones is relatively small, and the image is clearer. Therefore, four-dimensional color ultrasound at this stage can improve the effect.

2. Preparation before 4D color ultrasound

Although you need to hold your urine for B-ultrasound, you generally do not need to hold your urine for four-dimensional color ultrasound. If the pregnant woman is in May or June, she can choose appropriate clothing during the examination, such as maternity pants.

3. The whole process of 4D color Doppler ultrasound

Because pregnant women do four-dimensional color ultrasound mainly to check whether there are any abnormalities in the fetus in the uterus, the doctor will carefully check every part including the head, such as cleft lip, kidneys, heart, spina bifida, brain, bone dysplasia, etc., in order to start treatment as soon as possible. Therefore, it takes about 40 minutes for pregnant women to do four-dimensional color ultrasound.

4. Pregnant women should pay attention to the impact of 4D color Doppler ultrasound

The four-dimensional color ultrasound is a new generation of diagnostic equipment upgraded and developed after B-ultrasound. It is currently the most advanced obstetric diagnostic equipment in the world. It has no radiation and health effects on the fetus in the womb.
