The employment of ultrasonography in urology is not well established yet. On this purpose a survey of present situation in different medical setting was conducted. 200 questionnaires were filled by about 1000 physicians operating in various medical centers. The most of answers was provided by assistant head physicians (41\%) and head physicians (30\%), with a clear prevalence of urologists (64\%) and nephrologists (32\%). The number of beds reported by each centers ranged from 0 to 90, while the average doctor-patient ratio was 3.6. 72\% he centers could avail of B-mode echography (22\% of them owned an echo-Doppler velocimeter). The data obtained reveal the great heterogenety of present medical system and the necessity of finding a correct equilibrium between specialistic and primary care settings. It can be concluded that the correct use of ultrasonography depends both on good knowledge of its real indications and on the proper professional training of the echografist.
