尿动力学检查常用于评估下尿路功能。但是,其侵入性常会增加尿路感染发生的风险[1]。据报道[2-3],尿动力学检查后尿路感染的发生率为1%~30%。许多医院为了预防检查引起的尿路感染,在尿动力学检查过程中常规使用抗生素。然而,一些研究[4]显示使用抗生素并不能降低尿动力检查后 Urodynamic tests are commonly used to assess lower urinary tract function. However, their invasiveness often increases the risk of urinary tract infection [1]. It is reported [2-3], urodynamic examination urinary tract infection after the incidence of 1% to 30%.
