While urinary tract infections (UTIs) are uncommon in healthy men aged under 50 years, their prevalence rises in men aged over 65 years. UTIs can be classified as uncomplicated or complicated. UTI in men is considered to be more complicated than in women, because it is often related to abnormalities of the urinary tract, such as prostatic enlargement or a urethral stricture. UTI is associated with a significant disease burden and cost to patients and healthcare organisations. It is one of the most common reasons for prescription of antibiotics in primary care; however, because antibiotic resistance is becoming increasingly widespread, it is essential that these drugs are used prudently. The main strategy for preventing UTIs in men is to avoid the use of indwelling catheters.
