If there is pelvic fluid after total uterine excision, it depends on whether it is physiological pelvic fluid or pathological pelvic fluid; if it is physiological pelvic fluid, no treatment is needed; if it is pathological pelvic fluid, it is recommended that the patient undergoes medication, physiotherapy, and lifestyle improvement. If the ovaries are preserved after total hysterectomy, and the ovaries are in the ovulation period and ultrasound finds pelvic effusion, the patient does not have any uncomfortable symptoms, and gynecological examination does not find pelvic pressure and pain, etc., it is possible that it is physiological pelvic effusion, which does not need to be handled, and observation can be done. If there is pelvic fluid after total uterine excision, and at the same time the patient has symptoms such as pain in the lower abdomen and increased vaginal discharge, it may be caused by pelvic inflammatory diseases, which can be treated in the following ways: 1. Medication: antibiotic drugs are usually used for treatment, such as ampicillin, levofloxacin, metronidazole and so on. 2. Physical therapy: mainly infrared irradiation, microwave and other treatments to promote the absorption of inflammation. 3. Lifestyle improvement: patients need to pay attention to personal hygiene, change personal clothing, prohibit sexual intercourse. Eat more high-calorie, high-protein, high-vitamin food. Patients can also follow the doctor’s instructions for potassium permanganate diluted solution of sitz bath, to promote the local pelvic blood circulation, and promote the absorption of pelvic fluid. If the pelvic fluid is not relieved or is accompanied by other symptoms, the patient should go to the hospital in time to have the cause clarified and then be given targeted treatment.
