[The relevance between the effect on dysmenorrhea and the time of surgery of artery embolization in the treatment of adenomyosis].

OBJECTIVE: To analyze the relevance between the effect on dysmenorrhea of uterine artery embolization (UAE) in treatment of adenomyosis (AM) in different periods of the menstrual cycle and the time of the operation. METHODS: Totally 225 cases with preoperative dysmenorrhea voluntarily chose UAE in treatment of AM. They were divided into two groups according to the different times of menstrual cycle (proliferative phase or secretory phase). We analyzed the relevance between the effect of dysmenorrhea of patients in the two groups with the time of surgery after 1, 2, 3 and 4 years. RESULTS: (1) The numbers of the cases completely followed up were 142, 128, 119 and 101 each year in the following four years. (2) The effective rate on dysmenorrhea in the two groups of AM patients was 81% (43/53) and 76% (68/89) after 1 year (P > 0.05). (3) The effective rate was 75% (36/48) and 70% (56/80) after 2 years (P > 0.05). (4) The effective rate was 70% (32/46) and 63% (46/73) after 3 years (P > 0.05). (5) The effective rate was 63% (24/38) and 63% (40/63) after 4 years (P > 0.05). CONCLUSION: UAE has a good efficacy in treatment of AM, but the relevance is not significant between the time of surgery and the effectiveness on dysmenorrhea.
