Objective:To summarize the best evidence related to intermittent catheterization in adult patients with neurogenic bladder, and provide reference for clinical practice and patient self-management.Methods:According to the "6S" pyramid model, the system searched UpToDate, Guidelines International Network, European Association of Urology, UK National Institute for Health and Clinical Excellence, Scottish Interhospital Guidelines Network, Cochrane Library, PubMed, Web of Science, EmBase, EBSCO, OVID, Scopus, SinoMed, CNKI, Wanfang, VIP, Yimaitong, literature on intermittent catheterization of neurogenic bladder in adults, including clinical decision, best practice, guidelines, expert consensus, etc. The retrieval period was from the database establishment to August 2023. The search time was established until August 2023. The literature was screened by two research members, and four research members evaluated the quality of the literature and extracted the evidence.Results:A total of 14 articles were included, including 1 clinical decision, 1 evidence summary, 4 systematic reviews, 5 guidelines, 2 expert consensus, and 1 best practice. Finally, 31 pieces of best evidence were summarized, involving 5 aspects such as intermittent catheterization (IC) indication, IC timing, IC implementation process, IC health education, extended care.Conclusions:The evidence summary strictly follows the evidence-based process and the content of the evidence is comprehensive. The incidence of neurogenic bladder complications can be reduced by comprehensive management of intermittent catheterization, ultimately improving the quality of care. The localization characteristics should be combined in the application of evidence to improve the quality of life of patients.
