B-ultrasound is a necessary prenatal examination for pregnant women. Without timely examination, it may not be possible to detect any problems with the fetus in a timely manner. Some examinations may require certain requirements before being performed, such as fasting in the morning or holding urine. Do I need to hold my urine for prenatal examination and ultrasound?
During early pregnancy, holding urine is required for B-ultrasound examination, while during mid to late pregnancy, holding urine is not necessary for B-ultrasound examination. In early pregnancy, holding urine is necessary to create a sharp contrast between the urine and the gestational sac, which can provide a clearer understanding of the condition of the gestational sac. Before the examination, it is recommended to drink more water, usually 6 to 8 cups, and hold urine until you feel the urge to urinate. Do not hold it too much.
After the month, as the fetus continues to grow, the uterus will gradually enlarge. At this time, there is no need to hold urine for B-ultrasound, and normal examinations can also see the development of the fetus. In addition, it is allowed to eat before undergoing ultrasound, but it is important to avoid foods that are prone to bloating, such as milk, sweet potatoes, etc., to avoid affecting the examination results.
Additionally, there are two types of gynecological ultrasound, namely abdominal ultrasound and vaginal ultrasound. Abdominal ultrasound requires holding urine, while vaginal ultrasound does not. If there are no abnormal conditions, you can wait until 68 weeks of pregnancy to have a B-ultrasound to determine intrauterine pregnancy and embryo development. During this time, you can have your first B-ultrasound. If there are any abnormal conditions, you can go to the hospital for examination at any time.
