For the most part, I agree with what has already been said...
HOWEVER...I am a man, but the 2 nurses were not! They were professional about everything, so no blame on them - just my embarrassment. Being naked is bad enough, but I was instructed to lean back against a board that had a short, little seat with a bucket between my legs to catch the mess that I was going to make.
One of the purposes of the test is to determine how much urine I can hold before having to relieve yourself. As mentioned above they drain you and then start filling you up until you say
"uncle"!
One of the things that sometimes happens when my bladder is full is that it can cause a bowel movement too. I can't always tell before I get down to business
. So, to play it safe, I will often sit down to urinate. However, in this case, I knew I was going to have a BM.
The room we were in did not have a toilet, and I anxiously explained that I needed to have one quickly! They said just go ahead and do it while you are standing! I didn't have time to explain the science of kinetics and what to expect when something with mass hits a pain of urine. So, I quickly dried myself with the only towel they gave me, put on my clothes, and ran across the hall to the restroom. I made it in time, but just barely.
I hope this doesn't scare you, and I hope everything goes well for you.
