Recurrent UTIs are a common problem seen in clinical practice with important medical, social and financial implications. Prophylaxis of recurrent UTI is an ongoing challenge with several different management strategies being used (4). Low dose antibiotic prophylaxis for several months is effective, but fosters the development of antibiotic resistance of the causative microorganisms, but also the commensal flora.(4-8). In postmenopausal women vaginal estrogen therapy reduces symptomatic UTI episodes (1, 7). Further prevention strategies include the oral immunostimulant OM-89, the vaginal vaccine Urovac, lactobacilli prophylaxis, cranberry products and acupuncture (5, 7, 9).
