First suggestion is slow down. Just flush every 2-3 weeks. Forget the ultrasound for now, wait a year. It takes years to get stones so you are not going to get rid of them overnight.
Read your message from 10 months ago and at that time you already got good answers.
Improve your diet. Eat and apple a day or drink some apple juice for the malic acid, softens stones.
If you don't feel well drink a glass water with 1 tbs dissolved Epsom Salts in it and you will feel better but this is not a cure.
The ultrasound does not sound bad. Telman, if I remember right, did not have a clear US either. Read his blog, check under Telman.
