临床医生诊断泌尿道感染(下简称尿感),常依靠临床症状和脓尿,在可疑病例,才进一步作尿细菌培养,以确定诊断。故脓尿对诊断泌尿道感染,在临床上有一定意义。但尿沉淀中每高倍视野有多少白细胞才算是脓尿,各学者仍未统一意见,有待进一步探讨。此外,不少文献均提及,如不用清洁中段尿去作检查,很易发生脓尿的假阳性结果,但目前临床检查小便常规,一般不使用中段尿,这对尿感的诊断,究竟价值如何,值得进一步探索。本文的目的在于探讨:①尿沉淀中每高倍视野有多少白细胞才算是脓尿?才可以预告尿细菌定量培养>10~5/毫升;②清洁中段尿(下简称洁尿)和非清洁中段尿(下简称非洁尿)检查脓尿有什么不同结果。
Clinicians diagnose urinary tract infections (hereinafter referred to as urinary flu), often rely on clinical symptoms and pyuria in suspected cases, before further bacterial culture of urine to determine the diagnosis. Therefore, pyuria on the diagnosis of urinary tract infection, there is a certain clinical significance. However, urinary sediment per high power field how many white blood cells count as pyuria, the scholars have not yet unanimously agreed to be further explored. In addition, many references are mentioned, such as without cleaning the urine for examination, it is prone to pyuria false positive results, but the current clinical examination of urine routine, generally do not use the middle urine, which urine diagnosis, what is the value , Worth further exploration. The purpose of this article is to explore: ① urine sedimentation in each high power field how many white blood cells count to be pyuria? Can be informed of quantitative bacterial culture of urine> 10 ~ 5 / ml; ② clean the middle of urine (non-clean urine) and non- Under referred to non-clean urine) Check pyuria What is the difference.
