Study of clinical and paraclinical features in 24 children with urinary tract infection at Children hospital 1 from July 2003 to July 2004. Among them, there were 12 boys and 12 girls, 54.2% were aged 2 years or less and 45,8% aged more than 2 years. Out of the patients, urban to rural patient ratio was 58.3 to 41.7. Hospitalization times were regularly distributed in the year. Clinical symptoms: fever 62.5%, dysuria 33.3%, burning micturation 20.8%, pyuria 25%, hematuria 29.16%, diarrhea 4.2%, vomiting 4.2%. Urine test showed that: leucocyte esterase 95.9%; nitrite 54.2%;erythrocyte 41.7%, protein 41.7, Escherichia coli was isolated from urine in 58.3%. Blood test: leukocyte increased in 70.8%, CPR increased in 54.2%, creatinin is normal. Abnormal renal tract were 25% and vesicoureteral reflux occurred in 30.8%

Xanthogranulomatous pyelonephritis is an atypical form of severe chronic parenchymal infection and usually occurs in associated with urinary tract infection, obstruction and/or calculi. An accurate preoperative diagnosis is difficult because of its clinical and radiological similarities to various other renal lesions. We experienced two cases of xanthogranulomatous pyelonephritis, so we report with review of some literatures.

In this study, we have used various methods to define urinary tract infection in patients including Gram stain, leukocyte, leukocyte esterase, nitrite and culture of urine. Results have shown that all methods (no including nitrite) correspond to gold standard - urine culture method with regard to their sensitivity and specificity

Studying on 643 stone-induced urinary tract infection patients at hospital to evaluate of several methods in diagnosis of urinary tract infections by direct microscopic examination of urine and urine culture followed by microscopy. The results indicated: the rates of urinary tract infections defined by methods were different. All of methods (not include nitrite) were correspond to urine culture method. The specificity and sensitivity of direct microscopic methods such as Gram stain were 73.825% and 99.55%, of leukocyte is 85.65 % and 78.20%, respectively...

All 566 infants from 1-60 months of age treated at Thanh Nhan Hospital in the period Nov. 2001 – August 2002 underwent a culture of urine, among them 45 were infected urinarily (7.95%) with common symptoms such as fever, urinary disturbances. Their paraclinical signs were an increase of blood sedimentation, increase of neutrophile mononuclear white blood cells, in almost urinary proteins, urinary white blood cells were appeared; the younger age the higher rate of urinary infection (64.44% among 1-24 months of age subjects), the rate infection in boys is higher than in girls, in rural this rate is higher than urban subjects. In most urinary infections, there is a combination with other various conditions such as acute glomerulo-nephritis, fever with unknown causes, diarrhoea, especially in malnutritions infants

Xanthogranulomatous pyelonephritis of the kidney usually occurs in association with urinary tract infection. obstruction and calculi. The diagnosis is made when a nephrectomy is performed for a nonfunctioning kidney or a mass indistinguishable from carcinoma. We experienced incidentally a case of xanthogranulomatous pyelonephritis. so the pathologic features and clinical presentation were discussed and the literature was reviewed.

BACKGROUND: Rapid detection of bacteriuria is desirable for diagnosis and treatment of urinary tract infections. The aim of this study was to assess the usefulness of the cytocentrifuge Gram stain, uncentrifuged Gram stain, and urinary nitrite, leukocyte esterase to determine the exclusion of urine culture. METHODS: A cytocentrifuge Gram stain procedure and urine dipstick test were performed to screen for bacteriuria using 155 random fresh urine specimens submitted for routine culture. The authors compared the results of the cytocentrifuge Gram stain, urinary nitrite, leukocyte esterase and multiapplication of three tests with the results of culture. Result: Compared with positive urine culture(>105CFU/mL), cytocentrifuge Gram stain had a good negative predictive value(96.0%) and sensitivity(89.1%). The urinary nitrite and leukocyte esterase test had very low sensitivity(27.0%, 45.9%), respectively. The multiapplication of cytocentrifuge Gram stain, urinary nitrite and leukocyte esterase had a excellent negative predictive value(98.9%) and sensitivity(97.3%), and agree with urine culture positive(36/37 cases, 97.3%). CONCLUSION: Multiapplication of urinary cytocentrifuge Gram stain, nitrite and leukocyte esterase test is a useful screening test for the rapid exclusion of bacteriuria and provides rapid morphologic information about suspected pathogens in cases with positive urine culture.

Urinary tract infections (UTIs) are common infectious diseases, which can be associated with substantial morbidity and significant expenditures. This review highlights the current concepts and recent advances in our understanding and management of these conditions, specifically the pathogenesis, host factors, antimicrobial resistance, diagnosis and clinical approach to treatment. UTIs can be viewed as an interaction between specific bacterial virulence factors and the susceptibility of the host. For effective patient management, the critical step in the clinical management is to define the complicating urological factors. Current treatment trends for the reduction of UTI include empirical antimicrobial and short-course therapies. The management of complicated urinary tract infections is determined by the treatment of anatomical and functional abnormalities and antimicrobial therapy, as well as supportive care when needed. For the further proper management of UTIs, a profound understanding of their pathogenesis and a strict rationale for antimicrobial therapy, under constant surveillance, are required.
