Abstract
Bacillus Calmette-Guërin (BCG) has been traditionally used as a vaccine against tuberculosis (TB), which contains live, attenuated strain of Mycobacterium bovis. However, intravesical BCG administration has been used as an immunological treatment of superficial bladder cancer. Complications after bladder instillation of BCG are rare. We report a case of carcinoma urinary bladder with histopathologically proven granulomatous epididymo-orchitis (TB) after treatment with intravesical BCG.
