Re: Bladder tuberculosis
Genitourinary tuberculosis is one of the more "common" extrapulmonary manifestations of tuberculosis. No, there are generally no nitrites in the urine with GU TB, rather, one of the more typical signs is sterile pyuria...i.e. white cells in the urine with no evidence of bacterial infection.
This is NOT a sexually transmitted disease. People who have GU TB were exposed to pulmonary TB at some point in the past. The TB while never becoming symptomatic in the lungs was able to quietly spread to the lymphatics and make its way to the genitourinary system. Usually it's the kidney itself which is infected, but the tubercle bacilli can definitely pass down to the lower urinary tract and affect the bladder.
