Abstract:

BACKGROUND: Evidence has shown that the treatment of overactive bladder at the level of mucosal structure has a certain advantage, so the study on the possible involvement of mucosa in regulating bladder afferent signal transduction and improving the symptoms associated with overactive bladder has gradually become a hot spot.

OBJECTIVE: To review the role of signal pathways and receptors in various layers of mucosa in the pathogenesis of overactive bladder.
METHODS: With the key words of “overactive bladder, mucosa, urothelium, lamina propria, mechanisms" in both English and Chinese, CNKI, WanFang and PubMed were searched for relevant literature published from 2000 to 2020, and eventually 49 articles meeting the requirements were reviewed.
RESULTS AND CONCLUSION: The pathogenesis of overactive bladder is very complex. At present, there are few reports on whether the myogenic hypothesis and the neurogenic hypothesis interact with the mucosal signaling mechanism. Urothelial signaling pathway is the key of the current research, but the basement membrane layer and the lamina propria related signaling pathways are less reported. The various types of cells in the lamina propria and their functions have not been clear, and the relationship of mucosal signal with spinal cord center and senior center has not been fully research. Therefore, a horizontal study will be done on the relationship between the three types of pathogenesis of overactive bladder, and deeply and vertically explore the upstream or downstream of one of the three signal pathways, so as to provide a clearer target for the treatment of overactive bladder.

Key words: mucosa, overactive bladder, urothelium, signaling pathway, lamina propria, afferent signal, hypersensitivity, review
