Intravesical bacillus Calmette-Guérin (BCG) has been hypothesized to suppress inflammation within the bladder. A randomized, placebo-controlled trial in patients with refractory interstitial cystitis revealed borderline statistical significance for global response assessment questioning, as well as most secondary outcome measures, including capacity, pain scores, urgency/frequency symptoms, and interstitial cystitis inventories. [86] As with resiniferatoxin, the AUA currently recommends against this treatment. [80]
