Management of Recurrent Urinary Tract Infections in Women

Introduction to Recurrent UTIs

The European Association of Urology recommends that alpha-blockers like doxazosin should not be used for the treatment or prevention of recurrent UTIs in females, as they are not supported by evidence-based guidelines and do not address the underlying infectious etiology of recurrent UTIs 1, 2.
Recurrent UTIs in women are caused by bacterial reinfection, most commonly E. coli in approximately 75% of cases, requiring antimicrobial or preventive strategies that target bacterial pathogens, not urinary flow dynamics 3, 4.

The European Urology guidelines define recurrent UTI as ≥3 UTIs per year or ≥2 UTIs in 6 months 1, 5.
Urine culture should be obtained with each symptomatic episode before initiating treatment to confirm bacterial etiology and guide antimicrobial selection, as recommended by the American Urological Association 2, 6, 7.

The European Urology guidelines recommend using nitrofurantoin, trimethoprim-sulfamethoxazole (TMP-SMX), or fosfomycin for acute episodes based on local resistance patterns, with a treatment duration of ≤7 days to minimize antibiotic exposure while ensuring symptom resolution 1, 2, 6, 7.
Non-antimicrobial measures, such as increasing fluid intake in premenopausal women and vaginal estrogen replacement in postmenopausal women, are recommended as first-line prevention strategies, with a strong recommendation for vaginal estrogen replacement 1, 5, 8.
Immunoactive prophylaxis, such as OM-89, may be used to reduce recurrence in all age groups, although the evidence is not as strong as for other measures 1, 8.
Antimicrobial prophylaxis, such as continuous or postcoital antimicrobial prophylaxis, should be used only after non-antimicrobial interventions have failed, as recommended by the American Urological Association and the European Association of Urology 1, 2, 8.

Postmenopausal women should be evaluated for urinary incontinence, cystocele, high post-void residual urine, and atrophic vaginitis, as these conditions may contribute to recurrent UTIs, according to the American College of Radiology 1, 4, 9, 10.
Premenopausal women should be assessed for sexual activity patterns, use of spermicides/diaphragms, and voiding habits, as these factors may also contribute to recurrent UTIs, as recommended by the American College of Radiology 3, 4, 9.
