A Case of Bacillus Calmette-Guérin Cystitis Diagnosed with a Novel Loop-mediated Isothermal Amplification Method.

Intravesical bacillus Calmette-Guérin (BCG) instillation is broadly used to prevent bladder cancer recurrence or to treat carcinoma in situ. BCG infection is rare but can cause serious problems because this strain has intrinsic resistance to pyrazinamide, a first-line anti-tuberculosis drug. Furthermore, there had been no specific and easy procedure accurately diagnosing BCG infection. In this case report we present the first case of BCG cystitis diagnosed with a newly developed easy-to-use diagnostic procedure using the loop-mediated isothermal amplification method.
