[Therapeutic strategies in urinary tract infections in women].

Simple acute cystitis is cured by single-dose or 3-day treatment. Complicated acute cystitis requires clinical, bacteriological and imaging examinations. Treatment must be continued for 10 days and controlled. Acute pyelonephritis in women requires bacteriology, ultrasonography and plain x-rays and must be rapidly treated by fluoroquinolone or cephalosporin. High-risk acute pyelonephritis justifies admission to hospital, more elaborate examinations and active treatment.
