No residual tissue after uterine evacuation, but bleeding continues

Introduction
No residual tissue is found after curettage, but bleeding may still occur due to reasons such as ovulation period, incomplete uterine involution, or wound infection. Appropriate treatment should be based on the specific situation. The following is a detailed analysis: Curettage is primarily indicated for pregnant women within 12 weeks of gestation and mainly involves using machine-generated negative pressure to remove embryonic tissue from the uterus.
After a uterine evacuation procedure, the absence of residual tissue but continued bleeding may be caused by factors such as ovulation, incomplete uterine involution, or wound infection. Appropriate treatment should be based on the specific situation. Detailed explanations are as follows:
1. Ovulation Period
Uterine evacuation is primarily suitable for pregnant women within 12 weeks of gestation and involves using machine-generated negative pressure to suction embryonic tissue out of the uterus. If the patient recovers quickly after surgery and normal ovulation has resumed in the ovaries, slight shedding of the endometrium may occur, leading to postoperative bleeding despite no residual tissue. This is considered a normal phenomenon.
2. Incomplete Uterine Involution
If the patient has undergone multiple uterine evacuation procedures, the myometrial tissue of the uterus may be affected, resulting in reduced elasticity and incomplete uterine involution. This can prolong the discharge of bloody lochia and cause the aforementioned symptoms. It is recommended that patients receive treatment under medical guidance with medications such as ergometrine injection or misoprostol tablets.
3. Wound Infection
Following surgery, there is typically a small wound on the endometrial surface. If the patient does not maintain proper hygiene after surgery or uses contaminated sanitary products, external bacteria may invade and cause infection at the wound site. Inflammatory factors can exacerbate swelling and increase blood flow velocity, resulting in the described bleeding. Patients are advised to seek medical evaluation and appropriate management at a hospital.
In addition, conditions such as vaginitis, cervical cancer, or endometrial cancer could also cause this symptom. If the bleeding persists for an extended period, it is important to visit a hospital promptly to determine the underlying cause and receive targeted treatment.
