Ultrasound performed 42 days after cesarean section revealed echogenic spots or patches in the uterine cavity, which may represent residual fetal membranes or placental tissue presenting as echogenic spots or patches on ultrasound imaging. Poor uterine contraction after childbirth could also lead to retained decidua or other tissues in the uterine cavity, resulting in similar radiological findings.
In addition, inflammatory conditions such as endometritis may cause localized pathological changes in the endometrium, which can appear as abnormalities on ultrasound. It is recommended to monitor lochia discharge for signs of foul odor or increased volume.
Further testing of serum human chorionic gonadotropin (hCG) levels is advised to help determine whether any residual tissue remains viable. If hCG levels are elevated, a uterine evacuation procedure may need to be considered. If hCG levels are normal and there are no other discomforts, medications that promote uterine contractions, such as motherwort, may be used under medical supervision, along with regular follow-up ultrasounds to monitor changes in the echogenic spots or patches.
Meanwhile, attention should be paid to personal hygiene to avoid worsening infection, and excessive fatigue should be avoided during the postpartum recovery period to ensure adequate rest and promote uterine recovery.
