This factsheet is for women who are planning to have a hysteroscopy, or who would like information about it.
A hysteroscopy is a procedure that allows your surgeon to look inside your womb (uterus) using a narrow tube-like telescopic camera called a hysteroscope. The hysteroscope is very slim (about 3 to 5mm in diameter). It's carefully passed through the vagina and cervix (neck of the womb) and into your womb.
Your care will be adapted to meet your individual needs and may differ from what is described here. So it's important that you follow your surgeon's advice.
Hysteroscopy procedure can help find out what's causing symptoms such as unusual vaginal bleeding or discharge. It can also be used to check for certain womb conditions such as polyps (small growths of tissue in the womb lining), fibroids (non-cancerous growths of muscle in the womb), heavy periods or early signs of womb cancer.
During the procedure your surgeon may take a biopsy (a small sample of tissue) for examination in a laboratory, and/or treat the inside of your womb. It's also possible to remove polyps that may be found on your womb lining, as well as scar tissue and intra-uterine contraceptive devices (IUCDs) or "coils" that have become lost or stuck.
Depending on your symptoms and circumstances, it may be possible to examine your womb using pelvic ultrasound. This is a technique that uses sound waves to produce an image of the inside of your womb.
A simpler procedure, called endometrial aspiration, may be another alternative to a hysteroscopy and your surgeon will advise if this is suitable for you. This involves passing a narrow tube through your cervix and into your womb, and uses suction to remove samples of your womb lining. For most women, however, a hysteroscopy is the best option to help diagnose or treat the problem. Unlike other tests, it enables your surgeon to see directly into your womb.
Hysteroscopy is routinely done as an out-patient or day case and your surgeon will explain how to prepare for your procedure.
Hysteroscopy can be performed with or without a local anaesthetic, especially if it's only being used for a check-up (called a diagnostic hysteroscopy). A local anaesthetic completely blocks feeling from the area around your womb and you will stay awake during the procedure. Sometimes it's done under general anaesthesia, usually to treat a medical condition or to take a biopsy (called an operative hysteroscopy). This means you will be asleep during the procedure. Your surgeon will advise which type of anaesthesia is most suitable for you.
If you are having a local anaesthetic there is no need to go without food or drink before your hysteroscopy. If you are having a general anaesthetic, you will be asked to follow fasting instructions. Typically you must not eat or drink for about six hours before a general anaesthetic, although you will be allowed occasional sips of water until two hours beforehand.
At the hospital your nurse may do some tests such as checking your heart rate and blood pressure, and testing your urine.
You may be asked to sign a consent form. This confirms that you understand the risks, benefits and possible alternatives to the procedure and have given your permission for it to go ahead.
The procedure usually takes about 10 minutes to over half an hour, depending on what needs to be done.
Your surgeon may use a speculum to gently open your cervix (similar to having a smear test). The speculum is a device that's inserted into the vagina to help view the cervix. Your surgeon will clean your vagina and cervix with an antiseptic solution and pass the hysteroscope through the cervix and into your womb. He or she may pump gas or fluid into your womb to make it expand. This makes it easier to see the womb lining.
The camera at the end of the hysteroscope sends pictures from the inside of your womb to a video screen. Your doctor will look at these images and if necessary take a biopsy, remove polyps, and/or deliver treatment. This is done using special instruments passed inside the hysteroscope, and it's usually quick and painless.
When the examination is finished, the hysteroscope is gently taken out.

Where a hysteroscope is passed
If you have a biopsy or polyps removed, you may need to wear a sanitary towel to absorb any vaginal bleeding.
If you have a local anaesthetic, you will usually be able to go home after a short rest.
If you have general anaesthesia, you will need to rest until the effects of the anaesthetic have passed. You will need to arrange for someone to drive you home. You should try to have a friend or relative stay with you for the first 24 hours.
If you have a biopsy or polyps removed, the results will be ready several days later and will usually be sent in a report to the doctor who recommended your test. Other findings may be discussed before you leave the hospital.
If you have general anaesthesia, it's a good idea to have someone with you if the results are being discussed immediately after the procedure, as you may not remember the details clearly.
General anaesthesia can temporarily affect your coordination and reasoning skills, so you should not drive, drink alcohol, operate machinery or sign legal documents for 48 hours afterwards. If you are in any doubt about driving, please contact your motor insurer so that you are aware of their recommendations, and always follow your doctor's advice.
If you need pain relief, you can take over-the-counter painkillers such as paracetamol or ibuprofen. Follow the instructions in the patient information leaflet that comes with the medicine and ask your pharmacist for advice.
It's important to take it easy for the rest of the day. Some women feel ready to return to normal activities and work the day after the procedure; others may need to take two or three days off. Follow your doctor's advice about exercise, having sex and contraception.
You shouldn't use tampons for at least one month after your hysteroscopy to help reduce the risk of infection.
You may find that your first period following the hysteroscopy is heavier or more prolonged than usual and that your periods are irregular for a couple of months.
Most women don't have any problems after having a hysteroscopy. However, please contact your doctor if you develop:
Hysteroscopy is commonly performed and generally safe. However, in order to make an informed decision and give your consent, you need to be aware of the possible side-effects and the risk of complications of this procedure.
Side-effects are the unwanted, but mostly temporary effects of a successful procedure. After a hysteroscopy you may:
This is when problems occur during or after the procedure. Most women are not affected. The possible complications of any operation include an unexpected reaction to the anaesthetic, excessive bleeding or developing a blood clot, usually in a vein in the leg (deep vein thrombosis, DVT).
Specific complications of hysteroscopy are uncommon but it's possible to:
Your surgeon will be experienced at performing hysteroscopies. Rarely, this procedure isn't successfully completed and may need to be repeated.
The exact risks are specific to you and will differ for every woman, so we have not included statistics here. Ask your surgeon to explain how these risks apply to you.
