Abstract： Objective： To observe the clinical effect of kidney-warming and stasis-dissolving therapy based on menstrual phases in treating uterine adenomyosis．Methods：A total of 100 uterine adenomyosis patients treated at the Inpatient Department of Gynecology， Shengzhou Traditional Chinese Medicine Hospital from October 2022 to September 2024 were collected and randomly divided into a trial group and a control group，with 50 cases in each group using block randomization．The control group was treated with Shaofu Zhuyu Decoction，while the trial group received kidney-warming and stasis-dissolving therapy（administering Huayu Prescription from three days before menstruation until the end of the menstrual period and kidney-warming Prescription during the intermenstrual period）．The treatment lasted for three menstrual cycles．Hemorheological parameters [whole blood high shear viscosity（200/s），whole blood low shear viscosity（1 / s）， and plasma viscosity]， dysmenorrhea severity scores， traditional Chinese medicine syndrome scores， Visual Analogue Scale（VAS）for pain， uterine volume， and carbohydrate antigen 125（CA125） levels were compared before and after treatment between the two groups．Results：After treatment，the total effective rate was 88.00%（44/50）in the trial group and 78.00%（39/50）in the control group， with no significance in the difference（P＞0.05）．The cured and markedly improved rate was 52.00% (26/50) in the trial group and 32.00% (16/50) in the control group, with significance in the difference（P＜0.05）.In both groups， whole blood high shear viscosity， whole blood low shear viscosity，and plasma viscosity were decreased compared to before treatment（P＜0.05），with the trial group showing lower levels in all three parameters（P＜0.05）． Dysmenorrhea severity scores， traditional Chinese medicine syndrome scores，and VAS scores were decreased in both groups after treatment（P＜0.05），with the trial group having lower scores than the control group（P＜0.05）．After treatment，the uterine volume in the trial group decreased compared to before treatment（P＜0.05） and was smaller than that of the control group（P＜0.05）. In contrast，no statistically significant difference was observed in the control group before and after treatment（P＞0.05）. CA125 levels in both groups reduced compared to before treatment（P＜0.05），with the trial group showing lower levels than the control group（P＜0.05）. Conclusion： Kidney-warming and stasis-dissolving therapy based on menstrual phases can effectively alleviate clinical symptoms of uterine adenomyosis， reduce pain， shrink uterine volume， and improve hemorheological and serum CA125 levels.
