Abstract

Abstract : Key content: Bladder pain syndrome (BPS) presents as a spectrum of urological symptoms with poorly understood pathophysiology. Bladder mucosal injury secondary to low grade sub‐clinical infection is a possible trigger, leading to nociceptive upregulation and, subsequently, central sensitisation. Brain abnormalities associated with BPS suggest that neuropathological brain alterations exist, which may contribute to the perceived pain. Central sensitisation plays a role in the disease pathophysiology via an augmentation in the responsiveness of the central pain signalling neurons. The urinary microbiome is implicated as a trigger for the development and maintenance of BPS. Future directions to improve treatment strategies include stratification of patients with BPS into subtypes such as peripheral or central disease and investigation of the urinary microbiome and bladder barrier replacement. Learning objectives: To update clinicians' knowledge of current research into the urinary microbiome and pain sensitisation in BPS pathophysiology. To understand the biodiversity and abundance of urinary microbes and the role of peripheral and central pain sensitisation, which will help identify future management techniques for BPS. Ethical issues: What are the consequences of long‐term antibiotics use for BPS management on bacterial resistance?
