Do I need to hold my urine when doing ultrasound for threatened abortion?

Whether or not you need to hold your urine when doing an ultrasound for threatened abortion depends mainly on the specific examination method. Transabdominal ultrasound usually requires holding your urine, while transvaginal ultrasound does not. The doctor will choose the appropriate examination method based on the patient's specific situation.

1. Abdominal B-ultrasound requires holding urine

If a transabdominal ultrasound is used, this examination requires a full bladder to improve visibility of the uterus. In order to more clearly observe the growth of the embryo in the uterus, it is recommended to drink 500-800 ml of water before the examination and hold urine until the bladder is full. The specific amount of water to drink should be adjusted according to the doctor's advice to avoid discomfort caused by excessive drinking.

2 Transvaginal B-ultrasound does not require holding urine

If you are doing a transvaginal B-ultrasound, holding back urine will affect the examination results. Transvaginal B-ultrasound uses a probe to directly approach the uterus and pelvic cavity, which can observe the embryo more clearly without relying on auxiliary imaging of the bladder, so there is no need to hold back urine in advance. This method is suitable for patients who need a more accurate assessment of the risk of threatened abortion.

3. Basis for selection of inspection method

For patients with threatened miscarriage, transvaginal ultrasound is usually the preferred method because it can accurately assess the development of the embryo, fetal heart rate, and the intrauterine environment. It can also reduce the discomfort caused by a full bladder. However, in some cases, doctors may choose transabdominal ultrasound, such as when the patient is not suitable for transvaginal operation or there are other special circumstances.

Early diagnosis and management of threatened abortion is very important. Fully communicating with the doctor before the examination and understanding the specific precautions and examination methods can help ensure that the examination goes smoothly. If symptoms such as abdominal pain and vaginal bleeding occur, you should seek medical attention in time and follow the doctor's advice to ensure the safety of mother and baby.
