I need some expert advices to help my father to relieve from the severe bladder/urinary tract pain. My father is 74 and lives in China. 8 month ago he received a bladder cancer treatment. He received 7 times BCG treatment. At the 7th time of the BCG treatment, he suffered severe bladder and urinary tract pain. The pain persists for the past 8 months. The doctor believes that it developed to a bladder Tuberculosis. He has been taking anti tuberculosis drugs since the last BCG treatment but there is no sign of improvement. My father consulted many doctors, the advices are contradicted to each other’s. Now he is in the dilemma. Some doctors advice him continue to take anti tuberculosis drugs, otherwise the bladder tuberculosis can lose control; some others suggest that my father does not have the Tuberculosis. He should stop anti Tuberculosis drugs immediately. He did urine tests for 3 times, the results are all negative, but the doctor said that the urine test is not reliable while he is taking the anti Tuberculosis drugs.
I will appreciate it very much if someone can answer the questions:
1) Is there any chance that BCG treatment can cause Tuberculosis?
2) Can the negative urine test results (3 tests) be reliable sources to conclude that my father does not have the Tuberculosis?
3) My father’s urine is not cloudy/bloody, is this a indication that it’d not bladder Tuberculosis? Does bladder Tuberculosis cause pain?
