[Surgical site infection by bacillus Calmette-Guerin (BCG) after radical cystectomy, occurring after intravesical bcg therapy: a case report].

A 51-year-old man received 2 courses of intravesical bacillus Calmette-Guerin (BCG) therapy for carcinoma in situ of the bladder. Two years after the therapy, he underwent left radical nephroureterectomy, cystectomy, urethrectomy and construction of an ileal conduit because of left renal pelvic cancer and severe atrophic bladder. The histopathological diagnosis was carcinoma in situ of the left pelvis and ureter, and epithelioid cell granuloma of left kidney, prostate and bladder. After the operation, he developed extensive surgical site infection (SSI) by BCG, the diagnosis of which was delayed. He recovered from the SSI soon after anti-tuberculosis chemotherapy was begun. We discuss the requirements for more prompt diagnosis of SSI by BCG by analysis of this case.
