* Definition of bladder pain syndrome (BPS): complaint of suprapubic pain related to bladder filling, accompanied by other symptoms such as increased daytime and nighttime frequency, in the absence of proven urinary infection or other obvious pathology.

*** '''Differences that help to distinguish BPS include:'''
***# '''Painful nature of symptoms'''
***# '''Steady increase in pain with filling'''
***# '''More consistent voided volumes compared with OAB'''
***# '''Ability to defer voiding'''
