 Currently, the optimal treatment duration for male UTI is unknown. Only one randomized study showed no difference in outcomes, in patients treated with ciprofloxacin during 14 vs. 28 days. However, this study was underpowered and included patient in a single center. Current treatment guidelines are not consensual and recommend treating men with UTI for 7 to 4 or 6 weeks. Shorter durations may expose patients to recurrence when longer duration may be associated with increase in Clostridium difficile infection and antimicrobial resistance. Longer-duration treatment is also more costly and inconvenient to patients. Thus, since longer-duration treatment is associated with some adverse outcomes, in order to justify longer-duration treatment thee must be some clinically significant benefit to the extended treatment.
