Urologic Workup and Treatment for Chronic Urinary Tract Infections (UTIs)

Diagnostic Evaluation

The European Urology guidelines recommend confirming recurrent UTI diagnosis via urine culture before initiating treatment to guide appropriate therapy 1, 3
For women under 40 years with no risk factors, extensive routine workup (cystoscopy, full abdominal ultrasound) is not recommended 1, 2
For patients with persistent fever after 72 hours of treatment or clinical deterioration, consider contrast-enhanced CT scan or excretory urography 1
Evaluation of upper urinary tract via ultrasound should be performed in patients with high urine pH 1

Recognize that recurrent UTIs significantly impact quality of life, affecting social and sexual relationships, self-esteem, and work capacity 2
For postmenopausal women, assess for high postvoid residual urine volume 2, 3

For uncomplicated cystitis in women, the European Urology guidelines recommend Fosfomycin trometamol 3g single dose, or Nitrofurantoin macrocrystals 50-100mg four times daily for 5 days, or Nitrofurantoin monohydrate/macrocrystals 100mg twice daily for 5 days, or Pivmecillinam 400mg three times daily for 3-5 days 1, 2
For men with UTI, the European Urology guidelines recommend Trimethoprim-sulfamethoxazole 160/800mg twice daily for 7 days (if local resistance patterns permit) 1, 2
Fluoroquinolones can be prescribed based on local susceptibility testing 1, 2

The European Urology guidelines recommend non-pharmacological measures, such as advising premenopausal women to increase fluid intake 1, 2
Counsel regarding avoidance of risk factors 1, 2
For postmenopausal women, vaginal estrogen replacement is recommended (strong recommendation) 1, 2, 3
Immunoactive prophylaxis for all age groups is recommended (strong recommendation) 1, 2, 3
Methenamine hippurate for women without urinary tract abnormalities is recommended (strong recommendation) 1, 2, 3

Avoid fluoroquinolones as first-line empiric therapy due to increasing resistance and adverse effects 3
