16 year old female with no other issues, is having small amounts of blood in urine , white blood count in urine (doesn t grow in culture), many uric acid crystals in urine, ph level of 5, dull right flank pain & urine frequency. Ultrasounds & CT scans are normal with no stones. Urologist plans to treat overactive bladder with Vesicare . This does not explain blood in urine or dull flank pain. Just wondering what they may be missing.
