摘要
对５０例尿频尿急尿痛疑为泌尿系统感染患者的中段尿进行细菌培养，镜检尿沉渣噬菌细胞．其中细菌培养阳性２４人次（占４８％），阳性菌尿中均见噬菌细胞；另２６人次细菌培养阴性（占５２％），其中３例镜检见噬菌细胞，临床医师根据其典型临床症状，仍确定为泌尿系统感染．直接镜检尿中噬菌细胞，对泌尿系统感染患者具有早期诊断，提高诊断阳性率的优势．此方法快速，简便易行．
The midistream urine culture and the microscopic examination of the macrophages in the urine sediment from 50 cases have been taken, which had frequent micturition,precipitant urination and urethralgia,and was prediagnosed to be urinary tract infection.Midstream urine culture of 24 of them were positive(48%),and all of them showed macrophages in their urine,The midstream urine culture of the other 26 were negative(52%),and only three of them showed macrophages in urine,which also were proved to be urinary tract infection by symptomatic manifestation.Direct microscopic examination of macrophages in urine is helpful to initial diagnosis and can improve the positive rate of diagnosis.This method is rapid,simple and easy.
