Functional uterine bleeding can be classified into different types. Clinically, some functional uterine bleeding can cause a large amount of bleeding in the vagina in a short period of time. In such cases, hemostatic treatment is crucial. If the patient does not receive timely hemostatic treatment, the continued vaginal bleeding and increasing blood loss can potentially lead to hemorrhagic shock. Therefore, in clinical practice, if there is a significant amount of functional uterine bleeding, diagnostic curettage is often used as a treatment approach. This method not only serves a diagnostic purpose but also achieves immediate hemostatic effects in a short duration.
