I have stones on a pretty regular basis. The longest was about a month. I would have say if its been longer than a month you might want to get a ivp or ultrasound to see if they are still in there. If they are, they may not want come out on thier own and may require lithotripsy or surgery.

Thanks for your info. I think she's passed her stones. However, what I meant was, how long do they take to form new ones. Any ideas on that? Can new ones form in a month, year, etc.......??? Any ideas? Thanks.

I've been wondering that myself. I'll do some research and see what I find.

My thoughts are with your daughter...Poor baby...I just read that she's only ten. Kidney stones are so painful. :(

I found this:

jon marks, md: that varies with the composition of the stone. There are a number of different kinds of stones. Calcium stones are the most common – about 85% of stones. But, the calcium can exist in combination with other substances. Phosphates, oxylates. Stones can also be uric acid. The uric acid stones perhaps develop the most quickly, and as a result, can be treated by being dissolved with medication very often. But the calcium stones sometimes are years to form.


Do you know what kind of stone she had? Mine are calcium.

It also said that in a very young patient, it can be due to metabolic disorders. I'm not sure if your daughter has been tested for these?

I got my first stone at 18, which is relatively young. I've not been diagnosed with any metabolic disorders, but I do have a very slow metabolism.

Hi! Thanks for your info! I do not know what type of stones she had. The doctor said to save it and if she gets more, we will then analyze the stones. We are without insurance right now, so I haven't pursued doing that on my own yet either. My daughter also is now having twitches in her right arm. It started the other day, she vacuumed and I thought it was from that. However now that it has been several days, and i'm starting to think it is something else. She did go to the Dr. They said to drink alot of gatorade, and eat bananas. Possibly low potassium or something. It is like her arm is having spasms, between the elbow and shoulder. So now I am getting worried that between that and the kidney stones something metabolic is going on. So much to think about and consider. The Dr. Said if still twitching by monday (tomorrow) we will do some bloodwork. The kidney stones were definately a horrible thing for her to go through! She is the only one in the family, so it is not hereditary. Any more input is appreciated. Thanks again.
