Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Are there different sized tools for transvaginal ultrasound?Female, Canada, 27.I think I'm expecting to get a transvaginal ultrasound sound done today, my first ever. Problem is that although I'm an adult, my body has stunted growth and I also barely have any experience putting something in there. I've only put something in there long ago that's really small and the last was like 2 days ago when I had my pap exam. She used the pediatric sized tool and even that was on the painful side. So I'm really nervous about the upcoming one because I'm worried it will damage me if they don't see where to stop at. Will they be able to see where to stop the end of it and do they've different sized ones?. ### Response: The probes used for transvaginal ultrasound aren't that big, and are smaller diameter than a pediatric speculum like you would have had used for the Pap smear. Another thing you can do if you're comfortable with it is ask to insert the probe yourself, since it's more comfortable for many people..
