question: on Jan.10,2010 my PCR for urine Koch's was positive. my urologist prescribed me AKT-4 for 3months,AKt-3 for another 3 months & Rcinex450 for another 3 months. after eight & a half months of treatment I again tested for PCR urine for Koch's & Bectac culture of urine for T.B. The PCR was again positive after 8 months treatment & Bactac urine culture was negative after 15 days. final report of this culture on 02/11/10 is still awaited. Now please guide me how long should I continue with this treatment & what should be the treatment?
