Oral cholecystography has been proved useful and widely used as screening method in the gallbladder disease. The material consist of 1, 005 cases including 411 males and 591 females of oral cholecystography performed at Soon Chun Hyang Medical College Hospital during the last two years from 1977 to 1979. The authors analyzed relationship of gallbladder shape to cholelithiasis and biliary dyskinesia. The results obtained are as follows : 1. Among 1,005 cases, 414 cases were male and 591 cases were female. The female was predominant than the male and highly affected between 41-50 years of age. 2. Shape of the gallbladder was classified into the 9 type ; most popular type was pear type. 3. Incidence of gallstone was more common in septated and folding type than others. 4. Male to female ratio of gallstone was 54 ; 84 of total 138 cases, and peak age was 41 to 60 years (65.2%). 5. In 138 gallstone cases. opaque stones were 65 cases(47.1%) and nonopaque stones were 73 cases (52.9 ). 6. The emptying rate of gallbladder was faster in the male than the female, and faster in the older are group over 51 years than the younger age group below 30 years. Average emptying rate was 41.8%. 7. Biliary dyskinesia was predominant between the age of 31-40(37.3%), We classified the biliary dyskinesia into 3 types ; hyperkinetic dyskinesia, hypotonic dyskinesia and hypertonic dyskinesia. Most prevalent type was hypotonic dyskinesia. 24 cases(47.1%).
