There are generally two types of urine culture reports, qualitative and quantitative. Qualitative reports generally have three conditions: 1. positive: the common bacteria are E. coli, but the false positive rate is high because the midstream urine is easily contaminated; 2. negative: this condition has some value in ruling out urinary tract infections. Negative results can occur if the patient is receiving antibiotic treatment, the lesion site is not accessible to the ureter, a large amount of water causes dilution of the urine, and the urine stays in the bladder for too short a time. Therefore, a negative urine culture does not negate the existence of urinary tract infection; 3. More than one type of bacteria is cultured. This condition is mostly caused by contamination and it is difficult to determine the result. Therefore, pure qualitative urine culture cannot be used as a basis for confirming the diagnosis of urinary tract infection, while the quantitative culture method, by counting colonies cultured from urine specimens to distinguish contamination from infection, is of greater value for the diagnosis of urinary tract infection. In the quantitative culture report, if the number of bacteria cultured is ≥ 105 cfu/ml, it can be identified as infection; if the number of bacteria cultured is 1-105 cfu/ml, it is suspected infection and should be repeated; if more than one kind of bacterial growth is cultured, even if the number of bacteria is ≥ 105 cfu/ml, specimen contamination should be suspected; if more than two kinds of bacteria are cultured, the specimen is basically contaminated. For patients with pusuria, tuberculosis lesions should be suspected when the bacterial culture is negative. Common results of urine culture 1, acute simple cystitis If the number of bacteria cultured is ≥ 10?cfu/ml, it is generally suggestive of acute simple cystitis. Due to the stimulating effect of bacteria on the urethra and bladder mucosa, it mostly shows symptoms such as painful urination, frequent urination, urgent urination and difficult urination. For treatment, it is advisable to choose antibacterial drugs that are less toxic, easy to take orally and inexpensive, and the course of treatment is usually 3 days. During the treatment period, avoid spicy and greasy food, such as chili, ginger, garlic, fatty meat, etc., should also keep the vulva clean, prohibit sexual intercourse; 2, complicated urinary tract infection If the number of bacteria ≥ 105 cfu/ml is cultured, clinical manifestations of urinary frequency, urinary urgency, painful urination and other urinary tract symptoms, and accompanied by urinary obstruction or reflux, uremia, indwelling catheter, etc., mostly suggest complicated urinary tract infection. Because of the high degree of drug resistance of pathogenic bacteria in complicated urinary tract infections, antibacterial drugs need to be selected based on bacterial culture and drug sensitivity results. Mild and moderate infections can be treated in the outpatient clinic with oral antibacterial drugs for 10-14 days, while severe infections or suspected bacteraemia need to be treated in hospital. 3, asymptomatic bacteriuria More than 24 hours apart, two consecutive clean middle urine culture, colony count ≥ 105cfu/ml, and the same bacteria. Patients without urinary tract irritation symptoms, mostly seen in older women, usually do not need treatment. However, treatment is required for pregnant women, patients before and after urinary tract consultation operations, diabetic patients, immunodeficient individuals and preschool children.
