Urine specimens obtained from unprepped ambulatory females who voided into an unsterile disposable plastic cup showed a 95-per cent correlation with a catheterized specimen collected from a prepped patient through a sterile cystoscope. From these data, it appears that the midstream urine specimen and its unpleasant collection routine can be eliminated. We have found that specimens collected at anytime during voiding in unsterile disposable plastic cups result in reliable urine cultures.
从不做准备的门诊女性收集的尿液样本（这些女性对着一个未消毒的一次性塑料杯排尿）与通过无菌膀胱镜从做了准备的患者身上采集的导尿样本显示出95%的相关性。从这些数据来看，似乎可以省去中段尿样本及其令人不适的采集程序。我们发现，在排尿过程中任何时候收集到未消毒一次性塑料杯中的样本都能得到可靠的尿培养结果。
