A sonohysterogram is a diagnostic procedure used to evaluate the uterine cavity to determine if anything is in the uterine cavity that can prevent a pregnancy from occurring. It can also evaluate the fallopian tubes to ensure they are open, which is necessary for an egg to travel from the ovaries to the fallopian tubes and uterus to allow for fertilization. It involves the use of ultrasound imaging and a saline solution to provide detailed information on the uterus and fallopian tubes. Here are instructions on what to expect:

Preparation:

  • The doctor performing the sonohysterogram may be any gender.
  • Please abstain, or have protected intercourse, from the end of your period until after your sonohysterogram. Any chance of pregnancy will result in a cancellation of the sonohysterogram.
  • Please begin to take your antibiotics 2 days before the procedure. Please complete the full course of this medication as directed.
  • We recommend you take 2 Tylenol or Advil an hour before the procedure to help manage any discomfort.

Procedure:

  • You’ll be asked to lie down on an examination table, similar to the position for a pelvic exam, with your feet placed in stirrups.
  • A speculum is inserted into your vagina to visualize the cervix and to clean the area. This will feel similar to a PAP smear.
  • A small catheter is inserted through the cervix and into the uterine cavity. Through this catheter, a sterile saline (saltwater) solution is slowly injected into the uterus.
  • A transvaginal ultrasound probe is inserted into the vagina to provide images of the uterus and its lining.
  • The ultrasound probe is used to capture real-time images of the uterine cavity and fallopian tubes.
  • Once the examination is complete the catheter is withdrawn. The saline solution will discharge from the cavity similar to a period. The entire procedure takes approximately 5 minutes and can be uncomfortable for some patients.

Recovery:

  • You can usually resume your regular activities immediately after the procedure.
  • You may experience cramping, which should subside within a few hours.
  • Most people will need to wear a maxi pad for 12-24 hrs after the procedure

Possible Side Effects and Risks:

  • Common side effects include mild cramping and clear or pink vaginal discharge. In rare cases, infection or injury to the uterus may occur, so it’s essential to follow any post-procedure care instructions provided.
  • It’s important to communicate with the doctor before and during the procedure to address any concerns or questions you may have.
