概括
膀癌的尿液生物标志物测试显示出可变的性能. 虽然有些人提供临床实用性,但目前的测试尚未取代囊镜作为诊断和监测的黄金标准.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 生物标志物发现发现
背景情况:
- 膀癌的诊断和监测在很大程度上依赖于囊镜,这有助于提高医疗保健成本.
- 目前的尿细胞学不够准确,无法取代囊镜.
- 开发非侵入性,客观的基于尿液的分子测试旨在减少囊镜的频率.
研究的目的:
- 系统地审查美国商业上可用的尿液生物标志物测试的性能.
- 评估初始血检查和膀癌症监测的测试.
主要方法:
- 按照PRISMA指南进行系统的文献审查.
- 测试包括:NMP22,BTA,UroVysion,ImmunoCyt/uCyt,CxBladder和膀EpiCheck. 这些测试包括:
- 计算了传感度,特异性,负预测值 (NPV) 和正预测值 (PPV) 的中位数.
主要成果:
- 对于血工作 (5项测试,28项研究):灵敏度为65.7%-100%,特异性为62.5%-93.8%,NPV为94.2%-98.3%,PPV为29%-58.7%.
- 对于监测 (6项测试,14项研究):灵敏度为22.6%-92.0%,特异性为20.5%-97.9%,NPV为52.9%-96.5%,PPV为48.1%-75.7%.
结论:
- 尿液生物标志物测试表明,在膀癌管理中有一些临床效用.
- 目前没有一种测定方法有足够的证据来取代囊镜作为黄金标准的诊断工具.

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
440
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
