cholesterol kidney stone???

Hi, Everyone. I have a weird question for y'all: has anyone had a kidney stone made of cholesterol? I had a stone broken up by lithotripsy about 4 weeks ago; the tiny frament that was analyzed was a "100% cholesterol" according to the results sheet from the lab. I haven't talked to my urologist yet, but I will tomorrow......this is one strange stone. I have searched the internet, and no similar stone except for gallstones made of the stuff. Hmmmmmm...

Please reply if you know anything about this stone. Thanks!

I don't have an answer, but more a question or a possiblility:

Various lipids are all over the place in the body, and are part of every cell membrane. It's been discovered that people who tend to form stones have slightly different cell membranes from those who don't.

Stones are not a single chemical but are a matrix of crystals, and part of that matrix is protein or lipid in nature.

So I'm wondering if it is possible that the tiny fragment of the stone submitted for analysis--perhaps only a few molecules are used--just happened to be a part that was made up largely of lipids?

Let us know what the doc has to say about it.

Dear Robbbie,

Have you talked with your urologist?
What was his answer?
