[Complications of intravesical BCG therapy].

ABSTRACT

INTRODUCTION: BCG instillations are considered to be the standard of care therapy for superficial urothelial bladder carcinoma. Although serious adverse events are uncommon, the presence of high fever for at least two days in conjunction with systemic and/or local organ manifestations (except for urogenital symptoms), with the exclusion of other causes, suffice for the diagnosis of a disseminated BCG infection. Microbiologic detection of the pathogen is not necessary for diagnosis, as the detection of granuloma is more often successful and sufficient. Therapy for this infection includes oral Isoniazid, Rifampicin and Ethambutol for six months.
