Abstract

Background
Overactive bladder (OAB) and interstitial cystitis/bladder pain syndrome (IC/BPS) are debilitatingchronic bladder diseases that affect patients’ quality of life. Their etiologies and clinical phenotypes vary, and management strategies should be selected after excluding the possibilities of other pathological conditions with careful consideration of a multidisciplinary integrated approach to ensure optimal success.
Current Concepts
OAB is a symptom complex characterized by urinary urgency and frequency and nocturia with or without urge incontinence, and its key symptom is urinary urgency. IC/BPS has symptoms similar to lower urinary tract symptoms (LUTS) associated with OAB but also has distinctly different symptoms, including the key symptom of an unpleasant sensation or pain perceived to be related to the urinary bladder associated with LUTS. Recent studies have revealed that these key symptoms of OAB or IC/BPS are also observed in some patients with other diseases. Patients showing no evidence of bacterial infection on urine culture and experiencing LUTS or pain for more than 6 weeks should be considered as having OAB or IC/BPS. Treatment strategies for OAB and IC/BPS focus on managing LUTS and bothersome pain. Noninvasive management should be considered initially, whereas surgical options should be considered only after conservative treatment failure.
Discussion and Conclusion
OAB and IC/BPS symptoms overlap considerably in many patients. A more accurate differentiation of symptoms, including LUTS, would help achieve better treatment outcomes.
