Biopsy curettage is a common gynecological procedure, but for many patients it raises questions and creates uncertainties – what does it involve, what are the benefits, how long does recovery take, and what happens after the procedure? Discover when it is necessary, how to prepare for it, and what to expect, so that you are informed and prepared throughout the process.
Summary
Biopsy curettage is a gynecological procedure that removes tissue from the uterus or cervix for histopathological analysis, helping to accurately diagnose various conditions.
It is recommended in case of abnormal bleeding, suspected polyps, hyperplasia or precancerous lesions, guiding the appropriate treatment for each patient.
Preparing for curettage involves medical evaluation, preoperative tests, and following the doctor's instructions to reduce risks and ensure a safe procedure.
After curettage, bleeding occurs that can last between 3 and 7 days, and complete restoration of the endometrium and return of the menstrual cycle generally occur within 4-6 weeks.
It is important to observe temporary restrictions after the intervention, such as avoiding sexual contact, intravaginal tampons, and intense physical activities, to prevent complications.

What is biopsy curettage?
A biopsy curettage is a diagnostic gynecological procedure in which the doctor takes a tissue sample from inside the uterus or cervical canal for laboratory analysis. This medical intervention is essential for identifying and evaluating several conditions that can affect a woman's reproductive health.
The procedure consists of delicately removing a small amount of tissue from the uterine or cervical mucosa, which is then sent to the laboratory for histopathological examination. The main goal is to accurately diagnose various conditions, including inflammation, infection, precancerous changes or cancer, providing the doctor with the necessary information to establish an appropriate treatment plan.
Types of curettage: endocervical or endometrial?
There are two main types of biopsy curettage:
Endometrial curettage. It involves taking tissue from the inner layer of the uterus, known as the endometrium. It is often used to investigate abnormal bleeding or endometrial changes detected by ultrasound.
Endocervical curettage. This involves collecting samples from the cervical canal mucosa and is indicated when there are suspicions of abnormalities in the cervix.
Each type of procedure is tailored to the patient's specific diagnostic needs and the specialist's recommendations.
When is biopsy curettage necessary - from curettage for thickened endometrium to that required in case of bleeding
The gynecologist may recommend performing a biopsy curettage in various clinical situations, when there are suspicions of uterine or cervical abnormalities that require detailed investigation. This procedure becomes essential for establishing an accurate diagnosis and guiding subsequent therapeutic decisions.
Unusual bleeding
The main situations in which curettage is recommended include bleeding between periods, excessively heavy or prolonged periods, or bleeding after menopause, which requires investigation to clarify the cause.
Curettage for thickened endometrium
Abnormal thickening of the endometrium, detected by transvaginal ultrasound, can signal various conditions – from hormonal imbalances to precancerous changes. Curettage in case of thickened endometrium allows tissue sampling for histopathological analysis.
Curettage for endometrial polyps
The procedure is recommended when:
ultrasound suggests the presence of endometrial polyps;
Clinical symptoms raise suspicion of benign intrauterine formations.
Histological analysis confirms the nature of the polyps and excludes atypical changes.
Endometrial hyperplasia
In cases of excessive proliferation of endometrial cells (endometrial hyperplasia), curettage is necessary for:
confirmation of the diagnosis;
assessing the risk of progression to precancerous lesions or endometrial cancer.
Hemostatic curettage (emergency)
In situations of heavy uterine bleeding that does not respond to drug treatment, curettage can be used for both diagnostic and therapeutic purposes to stop the bleeding.
Once the need for the procedure is established, pre-operative preparation becomes important.
Preparing for the biopsy curettage procedure
Proper preparation for biopsy curettage is essential to ensure the success of the procedure and minimize risks. The process begins with a gynecological consultation, during which the doctor will collect detailed information about your medical history, including pre-existing conditions, known allergies, and current medication, if applicable.
Inform your doctor about any possibility of pregnancy, as the biopsy curettage procedure is contraindicated during pregnancy. Also, discuss with your doctor about temporarily adjusting your anticoagulants or medications that affect blood clotting.
Furthermore, it will be necessary to carry out the recommended preoperative investigations:
transvaginal ultrasound;
blood tests to assess coagulation function;
tests to rule out active genital infections.
Before the actual procedure, make sure to follow a few simple rules:
Avoid sexual contact, the use of tampons, and intravaginal intimate hygiene products for at least 24 hours before the procedure.
Take your prescribed painkiller an hour before the procedure to manage discomfort.
It is recommended to fast for at least 6 hours for solid foods and milk and at least 2 hours for clear liquids, before general anesthesia or deep sedation.
Once you fully understand the procedure, you will be required to sign informed consent forms.
How is the biopsy curettage procedure performed?
The biopsy curettage procedure is performed in a gynecological office and lasts, on average, between 15 and 30 minutes. The patient is positioned on the gynecological table in the standard position for pelvic examination, ensuring optimal access for the doctor to the area of interest.
The steps of the medical procedure are as follows:
inserting a vaginal speculum for clear visualization of the cervix;
cleaning the cervix with antiseptic solution to reduce the risk of infection;
performing local anesthesia, by injecting an anesthetic into the cervical tissue or applying sedation/general anesthesia, as appropriate;
dilation of the cervical canal, using dilators of progressively increasing sizes;
inserting the curette – a specialized medical instrument with a loop or sharp edge at the end;
performing controlled movements to delicately sample endometrial tissue from different areas of the uterine cavity;
collecting the sampled tissue in special containers with preservation solution;
withdrawing the instruments and monitoring the patient to rule out immediate complications.
An important aspect after the procedure is bleeding – although normal, in certain situations it may require close monitoring.
How long does bleeding last after biopsy curettage?
Vaginal bleeding after biopsy curettage is a normal manifestation, representing the body's natural response to the procedure. The duration and intensity of this bleeding varies considerably from one patient to another, being influenced by individual factors such as age, hormonal status and the reason for which the procedure was performed.
As for the normal duration of bleeding, it can last between 2 and 4 weeks: in the first days it manifests itself as a normal menstruation, having a bright red color and even small clots, after which it gradually reduces to spotting, taking on a pinkish or brownish hue.
Bleeding after biopsy curettage in menopause
For menopausal women, bleeding after biopsy curettage tends to be less intense and longer than during the reproductive period, because the uterine lining is thinned and hormonally inactive, which makes the volume of tissue sampled and local vascularity smaller.
Endometrial restoration after curettage
The process of endometrial regeneration after biopsy curettage is a natural and progressive phenomenon, essential for the restoration of normal reproductive function and regular menstrual cycles. Its duration varies from one woman to another, being influenced by factors such as the patient's age, hormonal status and the particularities of the procedure performed.
The endometrium has a remarkable capacity for regeneration, its cell layer renewing itself cyclically, under the influence of ovarian hormones. After curettage, this process of regeneration begins immediately, with the basal cells of the endometrium proliferating to reconstitute the functional layer removed during the procedure. Under normal conditions, complete regeneration of the endometrium occurs within a few weeks.
Return of the menstrual cycle after endometrial biopsy: When does menstruation occur after curettage?
In general, the menstrual cycle resumes within 4–6 weeks after the biopsy curettage. However, menstruation may be delayed or come earlier than usual, as the uterine lining needs time to regenerate. This period allows the endometrium to fully recover and the body to regulate its hormonal balance. It is important to note that the first menstruation after the procedure may be different from usual cycles: heavier, shorter or of an unusual duration.
In the months immediately following curettage, the menstrual cycle may show some irregularities. These variations are temporary, are considered normal and reflect the body's hormonal readjustment process. However, if menstruation does not occur within the mentioned interval or if the irregularities persist for more than three months, it is recommended to consult a doctor for further evaluation and to rule out possible complications.
What are you not allowed to do after curettage?
The recovery period after a biopsy requires following specific medical recommendations to ensure optimal healing and prevent potential complications. These temporary restrictions are essential to protect the healing tissues and reduce the risk of infection.
Avoid using internal tampons, opting exclusively for external absorbents, to prevent the introduction of bacteria into the vagina.
Vaginal douches are strictly contraindicated as they can disrupt the natural vaginal flora and increase the risk of infections.
Weight lifting, strenuous exercise, and running should be avoided in the first few weeks after the procedure.
Swimming in public waters, i.e. public pools, lakes or the sea, should be avoided until completely healed, due to the risk of infections.
Hot baths and saunas are also temporarily contraindicated, as excessive heat can intensify bleeding.
Alcohol consumption and smoking should also be avoided or significantly limited, as they can negatively influence the healing process.
Resumption of sexual life after biopsy curettage
Absence of sexual intercourse for a period of one to four weeks after the procedure is necessary to allow the cervix and endometrium to heal completely.
Thus, resuming sexual life after biopsy curettage should be discussed with the doctor during the follow-up consultation, as he will be the one who will evaluate the progress of the healing process and will be able to provide you with personalized recommendations.
Possible complications and when to contact your doctor
Although biopsy curettage is considered a safe procedure with a low risk profile, especially when performed by an experienced physician, there are certain complications that can occur, which patients should be informed about.
Thus, the risks and alarm signals that may arise include:
infections: persistent fever, above 38 degrees Celsius, chills, severe abdominal or pelvic pain, which progressively intensifies, vaginal discharge with an unpleasant odor or purulent discharge;
hemorrhage: very heavy bleeding, requiring changing the absorbent every hour, or removing large blood clots
uterine perforation: rare complication, which manifests itself in severe and acute abdominal pain, heavy bleeding and may require emergency surgery;
Asherman's syndrome (formation of intrauterine adhesions): can cause irregular or absent menstruation, chronic pelvic pain, and can affect fertility.
Knowing these risks and symptoms is essential for promptly identifying problems and seeking immediate medical attention when necessary.
Contact your doctor as soon as possible in case of:
very heavy bleeding that persists for more than a few hours;
fever over 38 degrees Celsius;
severe pain that does not respond to prescribed painkillers;
vaginal discharge with an unpleasant odor;
symptoms of shock, such as severe dizziness or fainting;
any other symptoms that worry you.
It is always preferable to seek medical advice when in doubt, rather than ignoring potential signs of complications.
Interpretation of endometrial biopsy results
The results of histopathological analysis of the tissue taken by curettage biopsy are usually available within one to two weeks of the procedure. These results provide essential information about the cellular structure and characteristics of the endometrial tissue, guiding subsequent therapeutic decisions and providing diagnostic clarity.
Types of possible outcomes
Normal or benign result – indicates the absence of abnormal or cancerous cells in the analyzed tissue, describing the appearance of the endometrium corresponding to the phase of the menstrual cycle;
Simple endometrial hyperplasia without atypia – a benign condition that can be managed with hormonal treatment and regular monitoring;
Hyperplasia with atypia – presents precancerous cellular changes and requires a more aggressive therapeutic approach, including intensive hormonal treatment or surgery;
Endometrial polyps – confirms the presence of these formations and excludes the presence of atypical or malignant cells;
Inflammatory changes or infections: identification of alterations caused by hormonal imbalances that require specific therapeutic approach.
A diagnosis of endometrial cancer requires further investigations to determine the stage and degree of differentiation of the tumor. The oncologist will work with the gynecologist to establish a personalized treatment plan, which may include surgery, radiotherapy, chemotherapy or hormonal therapy, depending on the specific characteristics of the cancer.
Each of these findings requires a specific therapeutic approach, tailored to the nature of the condition identified. It is essential to discuss the results in detail with your doctor, who will explain the clinical significance of the findings and recommend next steps for optimal management of your reproductive health.
The doctor will consider not only the biopsy results, but also your complete medical history, present symptoms, and other investigations performed, to create a personalized holistic care plan for you.
Understanding your biopsy results is just the beginning. Adopting a healthy lifestyle, with a balanced diet and regular exercise, can help maintain your reproductive health in the long term. By taking all of these steps, you will ensure proper care and enjoy a safe and speedy recovery.
