A urine preservative containing NaCl and polyvinyl-pyrrolidone has been in general use at this hospital for three years. It enables the specimen to be held at room temperature for 48 hours or more without appreciable change in the content of viable bacteria. The results of bacteriological tests performed on 2452 preserved urine specimens are compared with those from a control series examined before the method was introduced. A marked improvement in accuracy is demonstrated. The preservative can be very easily and cheaply prepared in any laboratory.
一种含有氯化钠和聚乙烯吡咯烷酮的尿液防腐剂已在本院普遍使用三年。它能使标本在室温下保存48小时或更长时间，而活菌含量无明显变化。对2452份保存尿液标本进行的细菌学检测结果与采用该方法之前检测的对照系列结果进行了比较。结果显示准确性有显著提高。这种防腐剂在任何实验室都能非常容易且低成本地制备。
