Abstract: Objective To analyze the practical cases and operations in the residents training of obstetrics and gynecology during their standard training, so as to establish the scientific training standards. Methods　Based on medical record information from 2012 to 2014 in a big maternity hospital in Beijing, we compared the practical cases and operations of the residents with the Rules for standardized training of residents in obstetrics and gynecology in Beijing. Results　Most residents fulfilled the set quota by the Rules, which means that they have got the basic clinical ability after the training. Both endometrial polyps and cervical intraepithelial neoplasia (CIN) Ⅲ were the leading cases in gynecological disease, whereas there is no corresponding requirements in the Rules.There was alack of severe cases for the residents to practice..The number of gynecological operations met the requirements of the Rules.There were three types of obstetricoperations, including RAM, lateral episiotomy suture and placental abruption, in which the residents failed to meet the lowest requirements of the Rules. Conclusion　The training hospitals should provide enough severe cases and common minor surgery for residents training,and Rules for standardized training of residents in obstetrics and gynecology in Beijing needs to be modified.
