Abstract
We report a case of ureteral obstruction and sepsis induced by bladder perforation following intravesical bacillus Calmette–
Guérin (BCG) that was successfully treated non-surgically. A 56-year-old man was diagnosed with non-muscle invasive
bladder cancer. He was treated with intravesical BCG instillation after transurethral resection of the bladder tumor. Just before
the 6th course of intravesical BCG, the patient was diagnosed with bladder perforation and developed ureteral obstruction
and sepsis associated with BCG. He was treated successfully with an antituberculous agent, antimicrobial chemotherapy and
percutaneous urine drainage. Bladder perforation associated with BCG is a very rare adverse event that causes severe sepsis.

Introduction
Intravesical bacillus Calmette–Guérin (BCG) therapy is use-
ful for adjuvant treatment of patients with high- and inter-
mediate-risk non-muscle-invasive bladder cancer (NMIBC)
[1–3]. The European Association of Urology (EAU) and
National Comprehensive Cancer Network (NCCN) guide-
lines recommend that patients with high- and intermediate-
risk NMIBC should be offered BCG therapy [4, 5]. The
EAU guideline states that the optimal BCG schedule for
induction BCG instillation is once weekly for 6 weeks.
For optimal efficacy, BCG must be given on a mainte-
nance schedule. However, intravesical BCG treatment,
despite its efficacy for tumor control, has a high frequency
rate of adverse events (AEs). The most common AEs are
cystitis, hematuria and fever, whereas a severe systemic
adverse reaction that requires anti-tuberculosis chemother-
apy and intensive care is rare [1, 6, 7]. Here, we report the
case of a patient who had bilateral ureteral obstruction and
sepsis induced by bladder perforation following intravesi-
cal BCG instillation who was successfully treated with an
