Novel strategy for cystitis glandularis: Oral treatment with cyclooxygenase‐2 inhibitor

Abstract

Cystitis glandularis, a proliferative disease of the bladder, is resistant to antibiotics, non-steroidal anti-inflammatory drugs, anti-allergy drugs and transurethral resection. Cystectomy or partial cystectomy is occasionally required for refractory cystitis glandularis. It has not been defined if cystitis glandularis is a premalignant lesion. We experienced a case of remission from cystitis glandularis after combination of oral treatment with selective cyclooxygenase-2 inhibitor, celecoxib and transurethral resection. Immunohistochemistry showed positive signals of cyclooxygenase-2 in the epithelium of pretreatment specimens, suggesting the pathophysiological role of cyclooxygenase-2 in cystitis glandularis. Here, we show the effectiveness of celecoxib against cystitis glandularis for the first time. Celecoxib could be one of the therapeutic strategies for cystitis glandularis.
