Abstract：
To evaluate the impact of external urine collection devices (UCD) on contamination of urine samples in women with symptoms of urinary tract infection.
This review was conducted according to the Systematic Reviews of Diagnostic Test Accuracy guidelines (PROSPERO CRD42021241758). PubMed was searched for paired sample studies and controlled trials. Studies comparing UCDs with non-invasive urine collection procedures were considered.
Only two studies were found. Neither of the two studies found any difference regarding contamination between specimens collected with the UCDs compared and non-invasive techniques. In the largest study, including 1264 symptomatic women, 18.8% of those allocated to UCDs failed to collect urine samples successfully.
More studies involving women with symptoms of urinary tract infection are needed to produce more robust data on the impact of these devices on urine contamination rates.

摘要：
背景：评估外部尿液收集装置（UCD）对有尿路感染症状的女性尿液样本污染的影响。
方法：本综述是根据诊断测试准确性指南（PROSPEROCRD42021241758）的系统综述进行的。搜索PubMed的配对样本研究和对照试验。考虑了将UCD与非侵入性尿液收集程序进行比较的研究。
结果：仅发现两项研究。两项研究均未发现使用UCD比较和非侵入性技术收集的标本之间的污染有任何差异。在最大的研究中，包括1264名有症状的女性,18.8％的UCD未能成功收集尿液样本。
结论：需要更多涉及有尿路感染症状的女性的研究，以产生更可靠的数据，说明这些设备对尿液污染率的影响。
