Based on your urinalysis results , were there other significant findings eg red blood cells, white blood cells, protein and casts?
If kidney stones are a differential here, I suggest that you have a kidney ,ureter and bladder scan to rule this out. A serum uric acid levels as well as serum calcium and phosphate levels may also help. A 24 hour urine collection sample to determine quantitative protein levels in the urine may be necessary. Calcium stones are the more common urinary stones in the urinary tract.
I suggest that you take plenty of water and modify your diet. Try to take only moderate amount of dairy products (cheese and milk) as this is high in calcium. Also, vegetables high in oxalate may also be avoided at this point.
You may discuss these with your physician. The presence of urinary tract stones do need further evaluation .In some cases, if the stones are large, they may require surgical intervention.
Is there any significant history of urinary tract stones in the family?
