OBJECTIVES
To examine (1) risk factors for urinary tract infection (UTI) during stroke rehabilitation and (2) the relation of postvoid residual (PVR) to the frequency of UTI.
DESIGN
Prospective case series.
SETTING
Academic specialty stroke rehabilitation service.
PARTICIPANTS
One hundred one consecutive admissions for stroke rehabilitation.
INTERVENTIONS
Not applicable. Main outcome measure Presence or absence of UTI.
RESULTS
Previously undiagnosed UTI was found in 28 of 101 subjects. Two or more PVR determinations of 150mL or more were an independent risk factor for UTI. In multivariate analysis, factors associated with increased risk of UTI included only use of beta-blockers and 2 peak PVR determinations of 150mL or more. Single determinations were not significant.
CONCLUSION
The optimal PVR for initiating bladder catheterization during stroke rehabilitation remains unknown, but the risk of UTI increases only when 2 or more ultrasound PVR readings are more than 150mL.
目的
研究（1）中风康复期间尿路感染（UTI）的危险因素，以及（2）残余尿量（PVR）与UTI发生频率的关系。
设计
前瞻性病例系列研究。
地点
学术专科中风康复服务机构。
参与者
101例连续入院接受中风康复治疗的患者。
干预措施
不适用。主要观察指标为是否存在UTI。
结果
101名受试者中，有28例此前未被诊断出UTI。两次或更多次PVR测定结果为150mL或更高是UTI的独立危险因素。在多变量分析中，与UTI风险增加相关的因素仅包括使用β受体阻滞剂以及两次PVR峰值测定结果为150mL或更高。单次测定结果无显著意义。
结论
中风康复期间启动膀胱导尿的最佳PVR仍不清楚，但只有当两次或更多次超声PVR读数超过150mL时，UTI风险才会增加。
