URINARY-TRACT INFECTIONS IN THE 90S - PATHOGENESIS AND MANAGEMENT

Urinary tract infections are one of the most common types of infection encountered in the practice of medicine. Recent discussions have focused on our current knowledge of natural host defenses that function during normal physiologic conditions in an attempt to prevent urinary infections. However, increased susceptibility to these infections may result from intrinsic risk factors that alter host defenses, or from extrinsic risk factors. Advances in the treatment of urinary infections have focused on short course therapy for women with uncomplicated lower tract infections, and on oral therapy in women with mild acute uncomplicated pyelonephritis. Also, in the area of prevention, reasonable candidates for antimicrobial prophylaxis have been identified. Even so, further studies are needed to define more clearly our understanding of the pathogenesis, treatment, and prevention of infections of the urinary tract.
