If she were mine, I'd go to ultrasound right now 1) because she has had stones before and it's best to check, and 2) xrays are worthless when ammonium urate stones are a possibility which are not uncommon in Yorkies. However, if she just had struvite before, you may be able to go with an xray.
Also, while she may need a special diet, the one she is currently on is not balanced and, over time, it could lead to other very serious health problems.
