title: Treatment of bacterial urinary tract infections: presence and future.
abstract: Bacterial urinary tract infections (UTIs) are frequent infections in the outpatient as well as in the nosocomial setting. The stratification into uncomplicated and complicated UTIs has proven to be clinically useful. Bacterial virulence factors on the one side and the integrity of the host defense mechanisms on the other side determine the course of the infection. In uncomplicated UTIs Escherichia coli is the leading organism, whereas in complicated UTIs the bacterial spectrum is much broader including Gram-negative and Gram-positive and often multiresistant organisms. The therapy of uncomplicated UTIs is almost exclusively antibacterial, whereas in complicated UTIs the complicating factors have to be treated as well. There are two predominant aims in the antimicrobial treatment of both uncomplicated and complicated UTIs: (i) rapid and effective response to therapy and prevention of recurrence of the individual patient treated; (ii) prevention of emergence of resistance to antimicrobial chemotherapy in the microbial environment. The main drawback of current antibiotic therapies is the emergence and rapid increase of antibiotic resistance. To combat this development several strategies can be followed. Decrease the amount of antibiotics administered, optimal dosing, prevention of infection and development of new antibiotic substances. The aim of this review is to highlight the current and to describe future treatment options for UTIs.
