The authors analyzed the activities of the sonographic laboratory during four consecutive months. During this period 896 patients were examined by ultrasonography and 119 of them (13.3%) for urgently indicated ultrasonography. The authors present a detailed evaluation of results in these 119 examined patients, in particular from the aspect of yield and asset of the method, affection of different organs, agreement of clinical and sonographic diagnoses and comparison with some other examination methods. Urgent ultrasonography is recommended as a very useful method, in particular as regards diagnostic yield which makes it possible to establish the diagnosis quickly and thus to start appropriate treatment early and to reduce thus the period spent by the patient in hospital. The method is useful also in serious cases and in some conditions which threaten the patient's life, as it can help early indication of surgery.
