Nonresectoscopic Endometrial Ablation


  • Nonresectoscopic endometrial ablation (EA) is a procedure done to destroy the endometrium. The endometrium is the lining of your uterus (womb). During your menstrual cycle (monthly period), your uterus sheds its lining, along with blood and mucus. You may need an EA procedure if you have very heavy vaginal bleeding during your monthly period. Endometrial ablation also may help stop abnormal vaginal bleeding caused by a uterine polyp or myoma (lump).
  • There are many different procedures that can be done for a nonresectoscopic EA. You and your caregiver will decide which procedure will work best for you. During the procedure, a catheter (thin tube) or device is inserted into your uterus through your vagina and cervix. Your cervix is the lower end of your uterus. Heat, ice, or electrical energy will then be used to destroy the lining of your uterus. Having this procedure may decrease abdominal (stomach) pain and cramping during your period. The amount you bleed during your period may be decreased. In some cases, after EA you may not have a period at all.


You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.


  • During your procedure, you may get a skin burn from the heated probe. You may have damage to your cervix, uterus, or nearby organs such as your bowels. After your procedure, you may have abdominal pain. You may have worse abdominal pain if you have had your fallopian tubes tied to prevent pregnancy. You may have nausea (upset stomach), vomiting (throwing up), and abdominal cramping. You also may have vaginal discharge and bleeding after the procedure. A blockage may form causing blood to pool inside your uterus. You may get an infection in your vagina, urinary tract, or uterus. Your infection may lead to sepsis, which is a blood infection and may be life-threatening.
  • Without this procedure, you may continue to have heavy bleeding during your monthly period. Heavy bleeding may cause anemia (low red blood cell count), dizziness, and a feeling of constant tiredness. Talk to your caregiver about any questions or concerns you have about the procedure.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered. If you have questions or concerns about having children after EA, talk to your caregiver.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.
  • Vital signs: Your vital signs will be checked before, during, and after your procedure. This includes taking your temperature, blood pressure, pulse (counting your heartbeat), and respirations (counting your breaths). To take your blood pressure, a cuff is put on your arm and tightened. The cuff is attached to a machine which gives your blood pressure reading. Caregivers may listen to your heart and lungs by using a stethoscope. Your vital signs are taken so caregivers can see how you are doing.
  • Pulse oximeter: A pulse oximeter is a device that measures the amount of oxygen in your blood. A cord with a clip or sticky strip is placed on your finger, ear, or toe. The other end of the cord is hooked to a machine. Never turn the pulse oximeter or alarm off. An alarm will sound if your oxygen level is low or cannot be read.
  • Pre-op care: You will be taken to the room where your procedure will be done. You will be placed on a table with your knees bent and feet in special holders. You may be given the following medicine:
    • Sedative: This medicine is given to help you stay calm and relaxed.
  • Anesthesia: Anesthesia medicine helps keep you comfortable during your procedure. You may get the following:
    • Local or monitored anesthesia: This medicine is given as a shot into your cervix. It is used to numb your cervix and dull your pain. With local anesthesia, you will be awake during the procedure. You may still feel pressure during your procedure, but you should not feel any pain. With monitored anesthesia care, you will be given medicine through an IV. This medicine keeps you comfortable, relaxed, and drowsy during the procedure.
    • General anesthesia: This is medicine that may be given in your IV or as a gas that you breathe. You may wear a face mask or have a tube placed in your mouth and throat. This tube is called an endotracheal (ET) tube. Usually you are asleep before caregivers put the tube into your throat. The ET tube is usually removed before you wake up. You are completely asleep and free from pain during procedure.

During your procedure:

  • One of the following procedures will be done:
    • Cryotherapy: Your cervix may be widened with a special tool. A probe with a cooling device on the tip will then be put into your uterus. The probe tip will be cooled until an ice ball forms in your uterus and freezes the lining. The ice will be allowed to melt and then the icing and melting may be repeated again. An ultrasound will be used to help your caregiver see the probe and the ice form.
    • Heated free fluid: A scope or hollow tube will be put into your uterus so caregivers can monitor the procedure. Heated fluid will then be put through the scope and into your uterus. The heat from the fluid will destroy your uterine lining.
    • Thermal balloon: A catheter with a balloon at the end will be put into your uterus. Your caregiver will fill the balloon with water that is heated by a machine. The heat of the water will destroy the lining of your uterus.
    • Microwave energy: A probe that can measure the temperature of your tissue lining will be placed inside your uterus. A scope will also be used to check the placement of the probe. The probe uses electromagnetic energy to heat the lining of your uterus and destroy it. The probe will be moved across your whole uterus before it is removed.
    • Radiofrequency: A device will be placed inside your uterus. The device will get larger when it reaches your uterus. There is a mesh at the end of the device that uses electrical energy to destroy your uterine lining. There is also suction at the end of the device to remove any steam or tissue during the procedure.

After your procedure:

You will be taken to a room where you will rest until you are fully awake. Do not get out of bed until your caregiver says it is okay. When your caregiver sees that you are not having any problems, you may be able to go home. If you are staying in the hospital, you will be taken back to you room.

  • Medicine:
    • Pain medicine: Caregivers may give you medicine to take away or decrease your pain.
      • Do not wait until the pain is severe to ask for your medicine. Tell caregivers if your pain does not decrease. The medicine may not work as well at controlling your pain if you wait too long to take it.
      • Pain medicine can make you dizzy or sleepy. Prevent falls by calling a caregiver when you want to get out of bed or if you need help.
    • Antinausea medicine: This medicine may be given to calm your stomach and control vomiting.
