146 initial and follow-up urine specimens of a urinary tract infection clinic were processed simultaneously by a dip-slide and by a standard pour plate method to evaluate the reliability of this simplified urine culture technique in a population with a high incidence of urinary tract infections. The dip-slide method gave false-negative results in only 8.7% of infected urines (greater than 10(5) cfu/ml urine), as determined by pour plate method. 1.3% false-positives were recorded. The false-negative rate rose to 22.2% when the dip-slide was used on the urines from patients on antimicrobial therapy. Our findings suggest that this simplified urine culture method is a useful tool even in populations with high incidence of urinary infections, although more careful evaluation of these test results is necessary when antimicrobial drugs are present in the urine specimens.
一家尿路感染诊所的146份初始尿液样本和随访尿液样本，同时采用浸片法和标准倾注平板法进行处理，以评估这种简化尿液培养技术在尿路感染高发人群中的可靠性。浸片法检测出的感染尿液（每毫升尿液中菌落形成单位大于10⁵）的假阴性结果仅占8.7%（以倾注平板法测定）。记录到的假阳性率为1.3%。当对接受抗菌治疗患者的尿液使用浸片法时，假阴性率上升至22.2%。我们的研究结果表明，即使在尿路感染高发人群中，这种简化尿液培养方法也是一种有用的工具，不过当尿液样本中存在抗菌药物时，有必要对这些检测结果进行更仔细的评估。
