尿路感染(urinary tract infections, UTI)是常见的临床感染,尿培养是诊断UTI的金标准,已在临床微生物实验室广泛开展。但是,尿培养在实际操作中还存在一些问题,例如是否对拟行尿培养的标本进行筛选以及如何筛选?哪些情况需要对尿沉渣进行涂片染色?如何理解尿培养菌落计数的临床价值?如何解释尿路感染培养出解脲棒杆菌的临床意义?门诊最常见的女性急性单纯性膀胱炎的尿培养结果如何解读?我们将依据近年来有关尿培养的研究进展,特别是近期发布的推荐性卫生行业标准——《尿路感染临床微生物实验室诊断》,对上述问题进行探讨。

Urinary tract infection (UTI) is a common infection in clinical practice, and the urine culture is regarded as the gold standard for final diagnosis and widely conducted in clinical microbiology laboratory. However, there are still some problems. These problems include whether it is necessary that all the urine specimens should be screened before culture, how to screen, under what conditions the urine specimens should be stained, how to understand correctly the clinical significance of the quantitative urine culture, how to understand the culture value of Corynebacterium urealyticum detected in UTI, and how to interpret the urinary culture results in acute cystitis in premenopausal women. The present review will discuss the above-mentioned issues in line with the studies in UTI, especially the recently-released health standards-the Diagnosis of Urinary Tract Infections in Clinical Microbiology Laboratory, recommended by National Health and Family Planning Commission of the People?s Republic of China.
