[Epidemiology of hospital-acquired urinary tract infections (author's transl)].

Among hospital-acquired infections, urinary tract infections are the widest spread. The most common pathogenic agents are E. coli, Enterococci and Proteus mirabilis. Indwelling bladder catheters account for about 70% of infections. Suprapubic urine drainage can reduce the incidence of urinary tract infections by approximatively 50%.
