Your stones are carbonate apatite which ic calcium phosphate.  Your blood tests are normal.  Urinary calcium is a little low but your urinary volume is good at 2800.  Given the high urinary volume, your citrate level is normal but a little low at 481 and I would usually recommend additional potassium citrate to get into the 700-800 mg/24 hour range.  Also check your urine pH (ackd/base) to make sure your pH doesn't rise above 7 when taking extra potassium citrate.  Additional calcium citrate would also be reasonable.  A 25  OH vitamin D level might be helpful.

Now see if your primary physician can help review this with you and order the medication.
