Oh my! I took my stepdaughter for her 1st one when she was 5, it was not good! I don't mean to scare you , and it could just be how she reacted, but it was awful! Firstly, I will say if by some chance they don't want you to go back with her, I would INSIST. I am sure a lot of it was fear on her side. but it took 3 of us to hold her down. She screamed while they were putting the cath in, but as soon as it was in she stopped. When they put the iodine (I think it was iodine) to sterilize the area, she complained about that burning. As soon as they started, they let her watch the monitor and and see everything that was going on, even when they made her pee they let her watch that. She winced a little bit when they pulled it out, but other then that she was fine. She had one at Community Hospital and 2 at The Cleveland Clinic and they were equally as bad.
It was so bad that she was saying, don't you love me, how could you let them do this too me? I said yes I love you, but they have to make you better, it will be over in just a minute. It is just horrible. Remember, they are depending on you for strength so try your hardest not to cry, it will just scare her more.
It ended up my stepdaughter had curved uriters and had to be on medication every night befoe she went to bed for 1 yr, and then another VCUG, more med for another yr and another VCUG. After the 2nd yr of meds (to help prevent reoccuring infections) she grew enough for er uriters to straighten out. There is a surgery that they can do Laproscopically (I think it Laproscopically) to straighten them. I think they put silcon in to help them straighten out.
Things might have changed, she is now almost 15 and has only had 2 UTIs in the past 8 yrs.
Good Luck and remember to be strong.
