Objective：To explore the disease constitution and some related characteristics of gynecological diseases by analyzing 3 974 hospitalized cases of hysterectomy and extended or radical hysterectomy. Methods：A retrospective analysis including disease constitution，average age，disease prognosis，wound healing，average length of stay and average cost，was done on 3 974 hospitalized cases of hysterectomy and extended or radical hysterectomy in the First Affiliated Hospital of Chongqing Medical University from 2007 to 2011. Results：Number of hospitalized cases and surgical operations in the department of gynecology in the hospital was increased year by year，but percentage of hysterectomy and extended or radical hysterectomy was declined to some different degrees. Among the 3 974 patients，average age was （47.96±9.65） years old，average length of stay was （12.77±7.55） d and average hospitalization cost was （14 303.70±7 939.39）. Cure rate was 80.9%，improvement rate was 17.8%，wound healing rate（A level） was 96.4% and wound heal－ing rate（B level） was 1.9%. The top five diseases were uterus myoma（31.38%），uterine malignant tumors（15.02%），uterine gland muscle sickness（11.55%），benign ovarian tumors（8.28%） and ovarian malignant tumor（7.02%）. Conclusions：Due to the improve－ment in diagnosis and treatment the concept and technology for gynecological disease，percentage of hysterectomy and extended or radical hysterectomy is decreased year by year，however，percentage of minimally invasive and noninvasive treatment is increased year by year.
