一、尿中查见脓细胞能诊断为尿路感染吗 尿常规检查,主张采集早晨第一次清洁中段尿,要求标本及时送检。所谓清洁中段尿,就是把一次尿分成初段、中段及末段来解,只将中间一段送检。若随便拿一点尿去检查,其结果的可靠性差。妇女尿易被白带污染,常可查见脓细胞;男性,尤其是少年。阴茎包皮长,冠状沟内常存积一些污垢,若不将包皮翻过来清洗后留尿检查,亦可造成同样误差。故尿中查见脓细胞,不一定是尿路感染,更不能作为诊断尿路感染的主要依据。临床是还要根据患者有无尿急、尿痛、尿频以及发热、腰痛等全身症状,以及其他血液检查等确诊。 二、有的尿路感染为何容易反复发作尿路感染反复发生,可能是重新感染;也可能是复发。若为复发,则多为肾盂肾炎。说明上次治疗失败。究其原因常见有:(1)所用抗生素对细菌不太敏感,或药量不足,或细菌已产生抗药性;(2)用药时间太短,可能用药1～2天症状消失后,病人自动停止用药;(3)肾脏内感染灶内有效药物浓度不足,
First, see the pus in urine can be diagnosed as urinary tract infection Urine routine examination, advocating the acquisition of the first clean urine in the morning, requiring specimens to be submitted in time. The so-called clean mid-urine, is a urine into the beginning, middle and end of the solution, only the middle of a submission. If you take a little urine to check, the reliability of the results is poor. Urine easily contaminated with leucorrhea, often see pus; men, especially juveniles. Penile foreskin long, coronal ditch often accumulate some dirt, if not turn the foreskin over to stay after cleaning urine examination, can also cause the same error. Therefore, check the urine see pus, not necessarily urinary tract infection, but can not be used as the main basis for the diagnosis of urinary tract infection. Clinical is also based on whether the patient has urinary urgency, dysuria, urinary frequency and fever, back pain and other systemic symptoms, and other blood tests confirmed. Second, some urinary tract infections easily recurrent urinary tract infections occur repeatedly, may be re-infection; may also be relapse. If the recurrence, then mostly pyelonephritis. The last treatment failed. The reasons are common: (1) the antibiotics used are not sensitive to bacteria, or insufficient dose, or bacteria have produced resistance; (2) medication time is too short, may be medication 1 to 2 days after symptoms disappear, the patient automatically stop Medication; (3) the concentration of effective drugs in the lesion in the kidney is not enough,
