Urinary Tract Infection


Normal urine is sterile. When bacteria enters the urinary system it is called urinary tract infection.

Dysuria is the most frequent chief complaint in men with UTI. The combination of dysuria, urinary frequency, and urinary urgency is about 75% predictive for UTI, whereas the acute onset of hesitancy, urinary dribbling, and slow stream is only about 33% predictive for UTI.

Common in children, middle and elderly people.

It is slightly more predominant in women
