Introduction

Whether a spontaneous abortion requires a dilation and curettage (D&C) depends on the specific circumstances. If an ultrasound examination shows no residual tissue in the uterine cavity after a spontaneous abortion, a D&C is usually not necessary. However, if the ultrasound reveals remaining tissue in the uterine cavity, a D&C may be required. After an abortion, it is important to rest, avoid sexual intercourse and tub bathing, and maintain good hygiene of the external genitalia.

Dilation and curettage (D&C) refers to the procedure of curettage. Generally, whether a D&C is needed after a natural miscarriage depends on specific circumstances. If an ultrasound examination shows no residual tissue within the uterine cavity after a natural miscarriage, a D&C usually is unnecessary; however, if ultrasound reveals residual tissue remaining in the uterine cavity after a natural miscarriage, a D&C might be required. If there is any discomfort, timely medical attention is recommended. A detailed explanation is as follows:

During a natural miscarriage, if the embryo and its associated tissues, such as the placenta and fetal membranes, are completely expelled from the uterine cavity, an ultrasound examination will show no residual tissue within the uterine cavity. In such cases, the uterus can contract and recover on its own without the need for a D&C. D&C is an invasive procedure that may carry risks such as infection and bleeding. Therefore, performing a D&C when there is no residual tissue is unnecessary.

If the miscarriage is incomplete, meaning the embryo and its associated tissues were not completely expelled from the uterine cavity, an ultrasound examination will reveal residual tissue in the uterine cavity. These residual tissues may lead to poor uterine contraction, causing persistent bleeding, infection, and other complications. To avoid these complications, a D&C is usually required to remove the residual tissue and promote uterine recovery.

After a miscarriage, attention should be paid to rest, avoiding sexual intercourse and tub bathing, maintaining external genital hygiene, and undergoing regular follow-up examinations to ensure proper physical recovery.
