I just scheduled my first ultrasound for Monday! The lady told me something I have not heard of before. She said that I need to start drinking water at 9 a.m. and I have to drink 36 oz before my appt with her at 10, and I can’t use the bathroom. Does anyone know what this is for? She might have told me, but my brain was concentrating on “How am I going to not pee for an hour after 36 oz of water?” Aggghhh! 🙂

@Anewmommatobe: They need your bladder to be bigger, that way they can see through it to look at the baby 🙂

Yes this is how it is with an ultrasound. Im not quite sure why. I had an ultrasound for an ovarian cyst when I was 15 and I had to drink SO much water and wasnt allowed to pee. It was almost painful by the time they started it.

Just found this to help bring some clarity.
Drink Water Beforehand
Your bladder lies in front of your uterus. When your bladder is full, your uterus is pushed up out of the pelvis and can be looked at more easily by ultrasound. When your bladder is empty, your uterus is farther down in your pelvis, where it is harder to see. The full bladder acts as a window between the outside of your abdomen and your uterus. You will probably be asked to drink 32 ounces (960ml) of water before you have the ultrasound and not to empty your bladder. With a vaginal ultrasound, your bladder doesn’t have to be full.

Yes, it helps them get a much clearer picture of the baby. You will have to pee and will probably get a headache from all the water, but it does help.

Having to pee is one of the most uncomfortable things to me. I have been waking up at least 3 times during the night to pee and I am only around 6 weeks.

I just had an ultrasound Saturday for a cyst but they told me not to drink water and empty my bladder. So I don’t know which one is true.

I only had to do this for my anatomy scans. The first time (18wks) was awful because they were running 30 minutes behind. The second time (21w4d) wasn’t bad at all. I made sure I was done drinking the 32 oz. of water 45 minutes prior to my appointment the second time (instead of the hour).
Just like PP have said, it gives a much clearer picture of the baby. I had a transvaginal ultrasound done for my first appointment, so I guess that’s why having a full bladder wasn’t necessary.

I havent had to do that at all yet. Actually for my last appt, they made me empty my bladder. I think it depends on the techs equipment and whether they are doing an internal or external.

@ohheavenlyday: is that why I have this awful headache today?? 🙁
I was in pain and cold sweats for my ultrasound today. They let me get up & use the restroom halfway through because I couldn’t take it anymore. I was either gonna pee my pants or puke, lol
Making a pregnant woman chug a ton of water & hold her pee in early pregnancy is just cruel!

My first ultrasound was in the ER b/c I was bleeding. They made me have a catheter, and they filled it up in order to fill my bladder. That was the most uncomfortable experience every. After that, I was glad to just drink some water and have to pee! The ride to the OB wasn’t very fun, but once I was on the table getting the ultrasound it was fine. The needing to pee feeling went away when I was in that position.

I had an ultrasound for ovarian cysts and it was the same thing. I can’t even imagine having to do this when I’m pregnant, because it was so full it was painful. I was worried I was going to pee my pants between the car and the waiting room. They let let up part way through the exam and asked me to release a dixie cup full because it was TOO much in there. Yeah… really fun to try to stop midway.
So fun to be a woman, eh?

I’ve been told to have a full bladder before each ultrasound (16 oz by an hour before the appt). Seems like standard procedure until you’re further along.

My first u/s they told me to do that but I knew if I started drinking it an entire hour before I’d be in so much pain. So I drank it on the way there and sure enough by the time I was called back my bladder was full and I was just starting to feel like I was going to explode! My second ultrasound I hadn’t had a drink of anything in a while but felt the need to urinate. I told the tech this (it was an emergency U/S) and she said my bladder was full and was able to see everything perfectly.

Yea since your bladder lies in front its almost like a baloon. You can’t see through a baloon when its deflated, but when its full of air (or in your bladders case, liquid) you can see through it!
