Most women with symptoms of urinary tract infections, culture must rarely and does not affect management. Urine culture is invaluable in these situations - in all patients with systemic symptoms of pyelonephritis, pregnant women, men and in patients who regularly and frequently UTI. Uncomplicated cystitis Microbiology limited to several pathogens. As many as 90 percent of uncomplicated episodes of cystitis caused by E. coli, 10 to 20 percent are caused by Staphylococcus saprophyticus koahulazonehativnye and 5 percent or less caused by other organisms Enterobacteriaceae or enterococci. In addition, the antimicrobial susceptibility of these organisms is quite predictable. In one third uropatohenov resistant to ampicillin and sulfonamides, but most are susceptible to trimethoprim-sulfamethoxazole (from 85 to 95 percent) and fluoroquinolones (95 percent). Due to the limited range of pathogens and their susceptibility predictable, urine culture and sensitivity was adding to the choice of antibiotics for treatment of acute uncomplicated cystitis in young women. Thus, urine cultures are no longer serving as part of routine work with these patients. Instead, these patients should undergo an abbreviated laboratory work in which the presence of pyuria is confirmed by traditional urinalysis (wet examination of grief threads urine), cell chamber counting technique or strips of dough on the leukocyte esterase. Positive test leukocyte esterase has reported sensitivity of 75 to 90 percent in detecting pyuria associated with UTI. Gram staining unspun urine can be used to detect bacteriuria. In this semi-quantitative test, one organism to field immersion correlates with 100,000 CFU per ml culture. Since the procedure
CFU per ml culture. Because the procedure is timeconsuming and has low sensitivity, it is usually not performed in most clinical laboratories if it is specifically requested. Test strips nitrites used as a surrogate marker for bacteriuria. Mochy probe becomes more affordable easy to use tool that can be used in any office of a doctor. While many disorders can be detected in strip, nitrite test and leukocyte oxidase test is most useful. Nitrite formed from nitrate reduction of urinary active bacteria while leukocytes oxidase reflects leukocytes in urine. If both are positive then UTI in more than 90% of cases. Positive Test for Nitrites a probe while the specific UTI is only 30% sensitivity. It should be noted that not all uropatohenov reducenitrates in nitrites. For example, enterococci, S. saprophyticus and Acinetobacter species and therefore give false-negative results. In patients with a high index of suspicion of UTI and a negative probe, direct strattera dosage urine and nitrates or nitrites in. For example, enterococci, S. saprophyticus and Acinetobacter species and therefore give false-negative results. In patients with a high index of suspicion of UTI and a negative probe, direct study of culture and urine or should be done to rule out infection as the cause piror symptoms. If the urine contains no bacteria, urethritis, vaginitis or prostatis be regarded as the most likely. Adenovirus and chemotherapeutic drugs can lead to bacterial, not cystits. Other factors include tuberculosis bladder stones, tumors of the bladder and interstitial cystitis. .
