Objective To explore the current status and influencing factors of clinical nurses′ knowledge, belief, and practice regar-ding intermittent catheterization in neurogenic bladder, and to provide a reference for formulating relevant training programs and management strategies. Methods From July to December 2025, a total of 2,075 clinical nurses were enrolled by convenience sampling.The general information questionnaire and the Knowledge-Attitude-Practice Questionnaire on Intermittent Catheterization for Neurogenic Bladder were adopted for investigation. Results The total score of clinical nurses′ knowledge, belief, and practice regarding intermittent catheterization in neurogenic bladder was 72.30±13.37.Multiple linear regression analysis showed that hospital level, professional title, implementation of intermittent catheterization, training frequency, region, and department were inf-luencing factors (all P＜0.05). Conclusion Clinical nurses showed a moderate level of knowledge-attitude-practice regarding intermittent catheterization for neurogenic bladder. Nursing managers should improve primary nursing quality control, strengthen training for junior nurses, promote diversified training, and build cross-regional academic exchange platforms to comprehensively elevate nurses′ relevant knowledge-attitude-practice level.
