Whether or not to remove one side of your pants for a uterine exam depends on the type of exam the patient is having. There are two types of uterine examinations: abdominal ultrasound and vaginal ultrasound. If a woman is having an abdominal ultrasound, she does not need to take off one side of her pants, but only needs to pull them down to her vagina. If a woman is having a vaginal ultrasound, she will need to take off one side of her pants because a vaginal ultrasound requires the ultrasound probe to be placed inside the woman’s vagina, so she will need to take off one side of her pants. Women who have abdominal ultrasound need to drink water before the examination to fill up their bladder so that they can have a better examination, while women who have vaginal ultrasound need to empty their bladder before the examination so that the examination time can be shortened. It is recommended that women should pay attention to bring their menstruation period before going to the hospital for examination so as not to affect the results of the examination, and should inform the doctor in time if they feel uncomfortable during the examination.
