Pus urine is a relatively common clinical symptom. Pus urine is mainly manifested by milky white cloudy urine, and in severe cases, there can be pus clots, which is usually common in urinary tract infections. Normal human urine usually contains a small amount of white blood cells. If the number of white blood cells in centrifuged urine is greater than or equal to 10 per high magnification field of view, abscess urine can be diagnosed. The initial determination of the lesion can usually be made based on the timing of the appearance of pusuria during urination and the accompanying symptoms. For initial pus urine is usually common in the case of urethritis and pus urine with symptoms of bladder irritation such as frequency, urgency, and painful urination, most of them are usually caused by cystitis. For full-blown pus urine with bladder irritation symptoms and back pain and fever often suggest the possible presence of pyelonephritis causing pus urine. Infections can be divided into non-specific infections and specific infections. Non-specific infections are commonly Escherichia coli var. coli, Mycobacterium formicans, etc.; specific infections are generally Mycobacterium tuberculosis infections and Neisseria gonorrhoeae infections.
