US and European guidance recommends updated classifications for UTI in men
Updated guidelines for the classification of UTI have been published in 2025 by the Infectious Diseases Society of America (IDSA) and the European Association of Urology (EAU) to reflect a shift from the traditional “uncomplicated” and “complicated” to one that no longer automatically defines UTI in men as complicated.
The IDSA now defines all uncomplicated UTIs, in both men and women, as an infection confined to the bladder, while all complicated UTIs in both sexes are those that extend beyond the bladder; thus treating male UTIs based on the extent of infection, rather than labeling all as complicated. The IDSA felt this update was needed to better align with clinical practice and to become more congruent with the available data on male UTI. The prior version of the IDSA UTI guidelines omitted UTI in men from their recommendations but given the aging US population it was recognised that UTI in men is a salient issue, and that evidence to support guidance for this population has improved.
The EAU has also moved away from the terms “uncomplicated” or “complicated” in its most recent guidance, and now proposes classification of UTIs in both sexes as either “localized” (cystitis) or “systemic” (involving fever or other systemic signs of infection).
