Uterine separation is a description of an ultrasound examination and often represents the presence of residue or fluid in the uterine cavity, resulting in separation of the uterine cavity from the endometrium. Uterine separation is commonly seen in cases of incomplete endometrial shedding after menstruation, residual embryonic tissue after miscarriage, endometrial adhesions, and endometritis, with the main symptom being vaginal bleeding with abdominal pain. If the endometrial shedding is incomplete after ageing or menstruation, causing separation of the uterine cavity, and there are no other symptoms, treatment may not be required. If symptoms appear, such as obvious abdominal pain, vaginal bleeding, or separation of the uterine cavity caused by other causes, treatment is required, and the treatment methods are mainly medication and surgery: 1. Endometritis can be treated with antibiotics such as cephalosporin and metronidazole under the guidance of a doctor; if the endometrial shedding is incomplete after menstruation, medicines such as motherwort granules can be taken to promote endometrial shedding; 2. Surgical treatment: it is common for uterine separation caused by residual embryonic tissue after abortion. Embryonic tissue residue after miscarriage can be treated with curettage; endometrial adhesions can be treated with hysteroscopy. Uterine evacuation is performed through the vagina with specialized surgical instruments to remove the residual uterine cavity. Endometrial adhesions are detected through the hysteroscope using a uterine probe and the adhesions are gradually separated using a vascular clamp. After surgery, patients need to take more bed rest and avoid heavy physical labor to prevent postoperative bleeding. Keeping the vulva clean to avoid pathogenic bacteria from entering the surgical wound through the vulva will help to reduce the chance of infection.
