Objective To investigate the association between lower urinary tract dysfunction and anxiety disorder in stroke patients through sites of the stroke and the characteristics of bladder urodynamic. Methods The stroke patients were selected and enrolled according to the revised diagnostic criteria by the 4th National Cerebral Vascular Academic Conference. The patients were divided into groups according to sites of stroke. The Self-rating Anxiety Scale (SAS) and urination log were recorded. The association between incidence of anxiety disorders and urination disorder were analyzed. The morbidity rate of frontal lobe injury were calculated statistically. Results The lower urinary tract dysfunction occurrence rate of the frontal stroke group was 1.75 times higher than that of non-frontal stroke group, and the occurrence rate of PSAD in the frontal stroke group was 2.16 times higher than that of non-frontal stroke group. LUTD prevalence increased significantly in patients with PSAD, and urodynamics test prompted that the bladder activity was signiifcantly higher. Conclusion Anxiety disorders and urination disorder after stroke are relatively common and the incidence of frontal stroke is signiifcantly higher, with urination disorder at urine storing stage as the majority. The senior cerebral function, daily life ability, mood after stroke, etc are associated on patients with abnormal urination. Urodynamic changes are mostly caused by overactive activity of bladder and the symptoms are not in consistence with urodynamic manifestation. The test should be done when necessary for further treatment.%目的：探讨卒中后下尿路功能障碍与焦虑障碍之间的关系，并通过病变部位及膀胱尿动力学方法探讨其相关联系。方法据第4届全国脑血管学术会议修订诊断标准筛选卒中患者，据梗死部位分组，入院后行焦虑自评量表（Self-rating Anxiety Scale，SAS）评分，记录其排尿日志，对焦虑障碍与排尿障碍的发生相关性进行分析，并统计额叶损伤患者的发病率。结果额叶卒中组比非额叶组卒中后下尿路功能障碍（lower urinary tract dysfunction，LUTD）发生率高约1.75倍，额叶卒中组比非额叶组卒中后焦虑障碍（post-stroke anxiety disorder，PSAD）发生率高约2.16倍。尿动力检查提示：LUTD伴焦虑障碍者膀胱活动度明显增高。结论卒中后焦虑障碍及排尿障碍较为常见，且额叶卒中的发生率更高，以储尿期排尿障碍为主。患者的排尿异常与其高级脑功能、日常生活能力、卒中后情绪等因素相关。尿流动力学改变多为逼尿肌过度活动，但症状与尿流动力学表现不完全一致，必要时应做此检查以利于进一步治疗。
