We do have a Urology forum on Med help with a doctor on board I would suggest you put your question to him there ..good luck..
I honestly would not even attempt to give you an opinion here as I am not medically qualified to do so. I will just tell you what I would do if it were me.
I would most definately get a second opinion. None of us wants to see our child undergo unnecessary procedures, particularly if the condition isn't causing any problems at this particular time. I would ask my Dr. what the ramifications are of not having the procedure done, and what the possible negatives are of having it done. Then, I would ask another specialist the same questions. I would then weigh the pro's and con's and make my decision. And I can tell you, my list of questions would be long. I do think it important to have a full understanding of what can or is likely to happen should this be left. There are a lot of conditions that may very well be anymptomatic, but that does not mean it may not cause her even more problems later for not being dealt with now. It's very possible that is not the case with this particular condition, but again, I think it's important to have that information as part of your decision making process.
Just my opinion. Whatever you decide, I wish you well.
