To fill the bladder for a B-ultrasound scan without urine, one can drink plenty of water, eat fresh fruits and vegetables, or have a transvaginal B-ultrasound scan if they are sexually active. Generally speaking, for an abdominal B-ultrasound scan, one needs to hold urine in the bladder to better examine the corresponding areas and avoid misdiagnosis and missed diagnosis. However, drinking water to hold urine may take time, so patience is required.
1. Drink plenty of water: To speed up the process of holding urine, one can drink plain water, as well as coffee and tea, which can help achieve the desired effect. It is recommended to have the B-ultrasound scan in the morning, as this avoids the need to urinate after waking up and prevents the situation of not having urine.
2. Drink fruit juice: In addition to drinking plenty of water, one can also choose to drink some fruit juices, which have diuretic effects, such as strawberry juice, watermelon juice, and apple juice. Furthermore, standing up and moving around or taking a walk while drinking water can help produce urine faster. If one is a married woman, they can opt for a transvaginal B-ultrasound scan.
3. No need to hold urine after 8 weeks of pregnancy: Not all gynecological abdominal B-ultrasound scans require holding urine. For example, after 8 weeks of pregnancy, the uterus enlarges and moves into the abdominal cavity, naturally pushing the intestines upwards. There is also amniotic fluid in the uterine cavity, so observing the fetus no longer requires holding urine.
