Can we leave cornual residue untreated?

Corner residue of the uterus refers to embryonic or placental tissue remaining in the uterine cornua. Whether intervention is necessary depends on the size of the residue and associated symptoms. Generally, small corner residues without symptoms can be observed without special treatment. However, larger residues with obvious symptoms require timely treatment, as leaving them untreated may lead to worsening complications. Specific analysis is as follows:

1. General Situation

If the uterine cornual residue is small—such as minor blood clots or tissue—and the patient currently has no noticeable symptoms or discomfort, special treatment may not be required. In most cases, the residue will naturally be expelled during menstruation. However, it is advisable to undergo a follow-up ultrasound after menstruation ends to confirm whether the residue has been completely cleared.

2. Special Situations

1) Large uterine cornual residue: If the residual tissue is large and cannot be naturally expelled, it may lead to more serious complications such as intrauterine adhesions, poor uterine contraction, or abnormal bleeding, which in severe cases could be life-threatening. Therefore, timely medical intervention is necessary, including procedures such as dilation and curettage (D&C) or hysteroscopic surgery.

2) Obvious symptoms: If the residue causes symptoms such as abdominal pain or a sensation of heaviness in the lower abdomen that significantly affect quality of life, prompt treatment is also recommended to prevent symptom progression.

Regardless of whether treatment is needed, patients should maintain good personal hygiene and attend regular follow-up appointments. Any abnormalities should be evaluated by a healthcare provider promptly, and management should be conducted under medical guidance. Additionally, appropriate physical activity is important; strenuous exercise should be avoided both before and during treatment.
