Mine are exactly the same ......................
My Dr suggested to stay away from calcium foods, supplements and stay away from oxalates, too.
So what's left to eat? lol :)
Actually there are many types of calcium plus stones, and many of these
form because of bacterial issues. So for us having multiple types of stones in not unusual.
I actually had a book with a list of different calcium stones or even calcium oxalate stones with others materials deposited on them. just like rocks sadly.
