[Problems of infectious hospitalism in the Hungarian urology]

1. In more than half of the urological basis disease an asymptomatic significant bacteruria is present. 2. The asymptomatic bacteruria must be treated, since it is a sign for endangering by pyelonephritis (potential pyelonephritis). 3. In our clinical material the distribution of the pathogenic agents has changed and that in favour of bacteria resistant to medicaments. 4. This appearance could be observed above all in patients who were hospitalised for a longer time and in the older age groups. 5. With all remedies at our disposal must be tried to reduce the resistance.
