Interstitial cystitis/painful bladder syndrome: appropriate diagnosis and management.

Interstitial cystitis/painful bladder syndrome (IC/PBS) is characterized by urinary frequency, urgency, and pelvic pain in the absence of any other identifiable pathology. Initial identification of IC/PBS is challenging, as patients may have a range of symptoms that overlap with other disorders, including urinary tract infection (UTI). These patients may be treated empirically with antibiotics; however, many patients with such symptoms are actually culture negative and are later diagnosed with IC/PBS. This review describes the importance of recognizing the symptom overlap between IC/PBS and UTI and focuses on approaches to the diagnosis and management of IC/PBS. Physicians can improve patient care by considering IC/PBS early in the differential diagnosis.
