Evaluation of Femoston and Dydrogesterone therapy for incomplete abortion: a retrospective cohort study.

Purpose: This study aimed to compare the efficacies of Femoston and Dydrogesterone therapy in patients with incomplete abortions.

Methods: Patients with incomplete abortions were included if they preferred medication over surgical intervention. The participants were categorized into three groups: the Femoston group received Femoston, the Dydrogesterone group was administered Dydrogesterone, and the control group was followed up without treatment. Basic clinical information, complete abortion success rate, and menstrual recovery rate were collected to evaluate the efficacy of Femoston and Dydrogesterone in patients with incomplete abortions.

Results: We analyzed 332 patients with incomplete abortions. The success rate of complete abortion was significantly higher in the Femoston group than in the control group (relative risk (RR)=1.708, 95% CI 1.304-2.237, p = .001) and the Dydrogesterone group (RR = 1.200, 95% CI 1.015-1.418, p = .023). The effectiveness of Dydrogesterone was also significantly higher than that in the control group (RR = 1.439, 95% CI 1.068-1.938, p = .015). After 60 days, the rate of menstrual recovery in the Femoston group was significantly higher than that in the control group (RR =1.322, 95% CI 1.103-1.609, p = .001), while the rate in the Dydrogesterone group was significantly lower than that in the Femoston group (RR =1.200, 95% CI 1.035-1.391, p = .009).

Conclusions: Femoston and Dydrogesterone were effective in treating incomplete abortions, with Femoston being more effective. Patients receiving Femoston had shorter menstrual recovery times than those receiving dydrogesterone. Therefore, Femoston and Dydrogesterone are potential treatment options for incomplete abortion, with Femoston being the more effective.
