Treatment Approach for Men with UTI Symptoms but Negative Urinalysis and History of Prostatitis

Clinical Considerations

The American Urological Association recommends treating men with UTI symptoms and a history of prostatitis with a fluoroquinolone (ciprofloxacin or levofloxacin) for 14 days, but only if local fluoroquinolone resistance is <10% and the patient has not used fluoroquinolones in the last 6 months; otherwise, use combination IV therapy with amoxicillin plus an aminoglycoside or a second-generation cephalosporin plus an aminoglycoside 1, 2
All UTIs in males are classified as complicated UTIs requiring longer treatment duration and broader antimicrobial coverage compared to female UTIs, according to the Infectious Diseases Society of America 1, 2

Urine culture and susceptibility testing is mandatory before initiating empirical therapy for all male UTIs, as this is a complicated UTI by definition, as recommended by the European Urology Association 1, 2
Perform digital rectal examination to evaluate for tender, boggy prostate suggesting acute exacerbation, as suggested by the European Urology Association 3

The standard duration of treatment is 14 days when prostatitis cannot be definitively excluded, according to the American Urological Association 1, 2
Fluoroquinolone resistance is a major concern—only use when local resistance <10%, as recommended by the Centers for Disease Control and Prevention 1
Prior fluoroquinolone exposure within 6 months predicts treatment failure, according to the Infectious Diseases Society of America 1, 2

Evaluate for bladder outlet obstruction, urinary retention, or structural abnormalities that may perpetuate infection, as recommended by the European Urology Association 3, 2
If recurrent infections occur, imaging and urological referral are warranted, according to the American Urological Association 3, 4
