The herbal medicinal product represent a multi-target therapy that includes diuretic, anti-inflammatory and antimicrobial aspects. Patients were randomized to one of the two treatment groups and treated with the phytotherapeutic agent or matching placebo for seven days. The primary endpoint was microbiologic response defined as reduction in bacterial urine culture counts by at least 10*2 CFU/ml.
