The purpose of our study was to evaluate the efficacy of Real-time and B-mode cholecystosonography immediately performed after one dose oral cholecystography. 861 patients have been studied: oral cholecystography gave non diagnosis in 92 cases (10.6%). Among these, ultrasonography demonstrated: in 39% stones in identifiable gallbladder; in 11% stones in non identifiable gallbladder; in 42.3% gallbladder completely normal; in 7.7% doubtful cases.
