Hi and thanks for your query, Your urinme cast and ctylogy is apparently within normal limits. However, doing a urinalysis for nitrites and leucocytes could be more informative in suggesting a urinary tract infetion. Urine cultures and a urethral saw could also be good options. However, there are situations where all of these tests are negative but symptoms persist. This is the case called chronic urethritis. Treatment usually involves particular combinationsof antibiotics for a give period of time. Meanwhile as you wait to take an appointment with a urologist for proper evalution, avoiding unprotected sex could be worthwhile. In case you got an active sexual partner, evaluating two of you for couple treatment is the best option. I suggest you take an appintment with a urologist. Thanks and best regards, Luchuo, MD.
