Abstract:

Uterine inversion refers to the plunging of the uterine fundus into the uterine cavity and the protrusion of the endometrium towards the vagina, which is mostly seen in the third postpartum stage, while non-puerperal uterine inversion is rare in clinical practice. We report the diagnosis and treatment of an adolescent patient with non-puerperal uterine inversion. The patient had massive vaginal bleeding with vaginal drainage before surgery, and after symptomatic treatment such as correction of anemia and anti-infection, the patient improved the relevant examination to indicate uterine inversion or uterine malformation, which was confirmed to be uterine inversion during operation. We had performed uterine reset surgery first. Considering the possibility of uterine malignancy during the surgery, it was suggested to send it to frozen pathology to decide the scope of operation. The family refused and requested direct hysterectomy. Therefore, we performed laparoscopic subtotal hysterectomy+bilateral salpingectomy. The postoperative pathological examination confirmed malignant mesenchymal tumor of the uterus. By reviewing the relevant literature on non-puerperal uterine inversion in the past 30 years at home and abroad, we summarize the diagnostic and treatment experience, improve clinicians′ understanding of the disease, avoid misdiagnosis and guide the clinic.
