Urine may contain pus (a condition known as pyuria) as seen from a person with sepsis due to a<unk> . Lower<unk>  is also referred to as a bladder<unk> . The most common symptoms are burning with urination and having to urinate frequently (or an urge to urinate) in the absence of vaginal discharge and significant pain. These symptoms may vary from mild to severe and in healthy women last an average of sixdays. Some pain above the pubic bone or in the lower back may be present. People experiencing an upper<unk> , or pyelonephritis, may experience flank pain, fever, or nausea and vomiting in addition to the classic symptoms of a lower<unk> . Rarely, the urine may appear bloody or contain visible pus in the urine. Children In young children, the only symptom of a<unk>  <unk>  may be a fever. Because of the lack of more obvious symptoms, when females under the age of two or uncircumcised males less than a year exhibit a fever, a culture of the urine is recommended by many medical associations. Infants may feed poorly, vomit, sleep more, or show signs of jaundice. In older children, new onset<unk>  incontinence (loss of bladder control) may occur. About 1 in 400 infants of 1 to 3 months of age with a<unk>  also have bacterial meningitis. Elderly<unk><unk>  symptoms are frequently lacking in the elderly. The presentations may be vague with incontinence, a change in mental status, or fatigue as the only symptoms, while some present to a health care provider with sepsis, an<unk>  of the blood, as the first symptoms. Diagnosis can be complicated by the fact that many elderly people have preexisting incontinence or dementia. It is reasonable to obtain a urine culture in those with signs of systemic<unk>  that may be unable to report<unk>  symptoms, such as when advanced dementia is present. Systemic signs of<unk>  include a fever or increase in temperature of more than from usual, chills, and an increased white blood cell count.
