Urinary Tract Infection News and Research

RSS

Urinary tract infections are a serious health problem affecting millions of people each year. Infections of the urinary tract are the second most common type of infection in the body. Urinary tract infections (UTIs) account for about 8.3 million doctor visits each year.* Women are especially prone to UTIs for reasons that are not yet well understood. One woman in five develops a UTI during her lifetime. UTIs in men are not as common as in women but can be very serious when they do occur.

New urine test shows which UTI antibiotic works in under six hours

Researchers have developed a rapid direct-from-urine test that identifies which first-line antibiotic is likely to work for a urinary tract infection in an average of 5.85 hours, instead of the usual two to three days. In studies of 352 routine urine samples and 90 duplicate preservative-tested samples, the method showed high agreement with standard testing, suggesting it could speed treatment and support efforts to curb antimicrobial resistance.
