Patient's question:
My wife said she's afraid she's not doing well enough on her own, so she wants to understand the process of prenatal testing first. Besides, does prenatal testing require holding urine?Doctor's answer:
If you are pregnant before 12 weeks, a thorough abdominal ultrasound examination requires a full bladder. The bladder must be filled to see the intrauterine condition. Currently, there is another thorough examination method, which is transvaginal ultrasound examination. Using a probe inserted through the vagina for examination does not require a full bladder, and it is necessary to empty the bladder before the examination. Both examination methods are acceptable. After 12 weeks of pregnancy, there is no need to hold urine for the examination.
