A clinical analysis has been made on 931 cases of tubal sterilization which were seen at the Department of Obstetrics and Gynecology, Yonsei Uneversity Medical Center from Jan. 1, 1965 to Dec. 31, 1972. The results are as follws ; 1) 931 cases of tubal sterilization were performed. Among them, 88.4% were abdominal procedures and the remaining 11.6% were vaginal procedures. 2) The main indications(motivations) for tubal sterilization were as follows ; Multiparity only …………………………………………………… 50.8% Gynecological indication accompanying multiparity ………… 31.4% Obstetrical indication accompanying multiparity …………… 16.3% Medical indication ………………………………………………… 1.5% 3) For recent 8 years, annual number of tubal sterilized patients has been increasing as well as the incidende of puerperal sterilization, but average age of tubal sterilized patients tended to be lowered with the decreased number of their living children. According to the sex ratio of their living children (male : female=129:100), the number of male had a slightly higher preponderance for having tubal sterilization. 4) Average age of tubal sterilized patients was 33.1 years. Average number of gravidity, living children and induced abortion were respectively 5.3, 3.5, 3.2, and 1.6. 5) Considering the shortest average postoperative hospital day(3.3 days) and the lowest morbidity rate (3.7%) as compared with those of the other abdominal and vaginal sterilizations, the postpartum tubal sterilization was the most convenient method, and it was performed usually on postpartum 1st day. 6) General anesthesia was performed in the majority of cases. 7) Among 931 tubal sterilizations, there was 1 failure in vaginal tubal sterilization. Failure rate was 0.1%.
