Kidney Stones Support Group

Stones are not usually black. Tan or off white and even brown seems to be normal. Blackish could be old blood clots, nothing to worry about if you have had a stone rattling around. You should try and collect any so they can be looked at by a lab. Ct will tell you if you have any stones. Regular X-ray is tough to see most stones unless they are calcium and you are a thin person. I am nether. Good luck

Im far from being a thin person. After hurting i have had alot of these blac things pass. they may not be black but looks like it. Thanks for your reply.

I've had around 30 stones in the past few years, and mine are so small I rarely see them. I've gotten black-ish stones, connected with white tissue, to grains of sand that are grey or white. It all depends on what they are made of and what they come out with, like blood clots around them. Mine are never seen on xray,, but usually on CT. It's also normal to get "sand" which is broken off pieces of the stones...those hurt too.

Thank you for your reply i am huting again but mostly around kidneys but i have had back surgery also and it is very tender back there. So this just making pain alot worse.
Cant wait for the 27th of this month to get results from CTscan.
