Does the prenatal ultrasound require a full bladder?

Patient's question:

Doctor, I am three months pregnant, so I need to do prenatal check-up tomorrow. Hello, do I need to hold urine for the prenatal ultrasound?

Doctor's answer:

According to your description, during prenatal examinations, pre-pregnancy gynecological ultrasound requires urination retention. In the case of urination retention, the bladder can be filled, which allows the uterus and related appendages to be more clearly visualized under ultrasound. You are three months pregnant, and in this case, transvaginal ultrasound cannot be performed. Transvaginal ultrasound does not require urination retention. Pay attention to drinking more water to better retain urine. In addition to treatment, pay attention to maintaining sleep. Sufficient sleep will help you recover from illness as soon as possible.
