Post flush ultrasounds

Unfortunately I was recently told that I need to have my gallbladder removed. I have been reading through many of the posts here and feel somewhat encouraged that I might possibly be able to avoid this, especially at the age of 28. Doing research on the net, I have seen some people question whether the stones passed are really stones as opposed to some "compound" formed from the olive oil and other material. I'm wondering if anyone has actually had their stones analyzed and/or had an ultrasound after the flush process which shows a decrease in stones when compared to a previous ultrasound. Beyond this, I have seen some advice not to do the flush if you have calcified stones, yet I see some of you have passed calcified stones during your flushes, is there somewhat of a concensus as to whether the flush is safe if you have calcified stones? Thank you everyone and good luck with your health!
