Erste Erfahrungen bei der intraoperativen Steinsuche mittels Ultraschall P. Faul, E. Engels Urologische Abteil ung des Stadtkrankenhauses Me mmingen (Cheferz t : Prof. Dr. med. Peter Faull First Experiences in Intr aoperat ive Probing fo r Calculi Via Ult rasou nd The possibility of in traoperat ive probing for renal calculi via ultrasonography is examined experime nta lly in a pig's kidney full of calculi , in a water-bath . It was possible to locate safely even small calculi the diameter of which was as minute as 3 mm ; location was eff ected by means of their ty pical echo pattern . Encouraged by this fact we conducted intrao perati ve probi ng for calculi by means of a Real-time scanner supplied by Toshiba, in six patients to dat e. Intr aoperative probing f or calculi possesses advantages over conventio nal roentgenography and enables safe localisation of radiolucent concrements as ..-.el l. Zu sa mmenf assung Die M oglichkeit der intraoperativen Steinsuche mittels Ultr aschall wird experimentell an einer steingefUllten Schwelnentere im Wasserbad untersucht. Debet konnten auch klei ne Ster ne bis zu einem Du rchmesser von 3 mrn aufgrund ihres tvpiscnen Schall mu sters zuverlassig lokatislert w e-den . Ermutigt durch d lese Tatsache, wurde be l bisher sechs Kranken die int raoperative St einsuche min els reel-time-Scanner der Firma T oshiba mit gutem Erfolg durchgefuhrt . Di e imraoperat ive Steinsuche minels Ul trascharl besitzt gegenuber der bisher iib lichen Rontgentechnik Vorteile und bletet die M oglichkeit , auch nicht schatt engebende Ko nkremente sicher 10kalisieren zu k onn en.
