现将无白细胞尿的肾盂肾炎6例分析如下。临床资料详见附表。讨论一、诊断(一)尿路感染:诊断主要依靠尿细菌学检查,当尿常规无白细胞尿时,容易漏诊。清洁中段尿细菌培养球菌10~3～10~4/ml,尿沉渣革兰氏染色涂片细菌>1/油镜视野,膀胱穿刺尿培养细菌(+)均有诊断意义。本文6例符合,而涂片查菌且可弥补在应用抗生素药物等情况下培养不能生长细菌的缺点。2例厌氧菌亚硝酸盐试验阳性,可能意味着混合感染,上述检查互相补充,提高了诊断率。(二)肾盂肾炎:①临床特点,体温38～39.8℃4例(3例入院时已无热),腰痛4例,肾区叩痛及输尿管压痛2例。②6例均有蛋白尿(+～++),例6肾盂造影右肾盂饱满。③例2、5、6入院前后用抗菌素≥2种,前 Sixty cases of pyelonephritis without leukocytosis are as follows. Clinical data see the attached table. Discussion First, the diagnosis (a) urinary tract infection: the diagnosis depends mainly on urinary bacteriological examination, when the urine routine without leukocyturia, easy to missed diagnosis. In the middle stage of cleaning, the bacterial culture cocci of 10 ~ 3 ~ 10 ~ 4 / ml, urinary sediment gram stain smear bacteria> 1 / oil mirror field of view, bladder puncture urine culture bacteria (+) have diagnostic significance. The six cases of this paper, smear smear bacteria and can make up for the application of antibiotics and other cases of bacteria can not grow disadvantage. Two cases of anaerobic bacteria nitrite test positive, may mean mixed infection, the above tests complement each other to improve the diagnostic rate. (B) pyelonephritis: ① clinical features, body temperature 38 ~ 39.8 ℃ 4 cases (3 cases had no fever at admission), 4 cases of low back pain, renal area percussion pain and ureteral tenderness in 2 cases. ② 6 cases had proteinuria (+ ~ + +), 6 cases of pyelography right renal pelvis full. ③ cases 2,5,6 before and after admission with antibiotics ≥ 2 species, before
