Overactive bladder syndrome may be precipitated by the recent stone incidence because you have paid attention to your urinary function. Benign blood and urine results rule out physical condition of the urinary tract. You can try BLADDER RETRAINING for this syndrome.

Diseases are not solely diagnosed based on labs. You need a good Urologic exam for diagnosis. Get one. In the meantime drink moderate amt of water daily and avoid excess of beer, sodas, coffee and tea. Hope you do well
