Hydrosalpinx

Disease Description (Causes and Symptoms)

• Definition: A condition in which the end of the fallopian tube (the ampulla or distal fallopian tube) becomes blocked, causing fluid to accumulate inside the tube and resulting in its enlargement (making it look like a fluid-filled sac).
• Causes: Pelvic inflammatory disease (PID) is the most common cause and usually occurs after infection with sexually transmitted bacteria (Chlamydia or gonorrhea). Other possible causes include abdominal surgery, inflammation related to an intrauterine device (IUD), tuberculous salpingitis, and previous damage to the uterus or fallopian tubes.
• Pathophysiology: When the distal fallopian tube becomes obstructed due to chronic inflammation and fibrosis, fluid secreted by the epithelium cannot drain, causing fluid to accumulate inside the tube and resulting in enlargement. This fluid can adversely affect fertilization and implantation and, due to inflammatory or toxic substances, can lower the embryo implantation rate and worsen in vitro fertilization (IVF) outcomes.
• Main symptoms: Infertility (the most common clinical problem), chronic pelvic pain or intermittent pain, dyspareunia, oligomenorrhea, or abnormal uterine bleeding. Many cases are asymptomatic.

Treatment Methods

• Conservative/medical treatment
  • If acute PID is present, appropriate antibiotic treatment (broad-spectrum antibiotic therapy according to guidelines).
  • Percutaneous or transvaginal drainage of the fluid by aspiration alone may provide only temporary improvement because recurrence is common.
• Surgical treatment
  • Procedures that can be performed together with diagnosis through laparoscopy:
    • Salpingectomy: Particularly when IVF is planned, salpingectomy is often recommended because there is evidence that it increases the IVF success rate.
    • Salpingostomy/fimbrioplasty: A procedure to reopen the end of the fallopian tube. It aims to preserve reproductive function, but carries a risk of restenosis and recurrence.
    • Proximal tubal occlusion (ligation or sealing of the proximal fallopian tube): An option selected for IVF purposes only.
• Infertility treatment-related considerations
  • IVF is recommended when the fallopian tubes are severely damaged or the success rate of reconstructive surgery is low. When hydrosalpinx is present, salpingectomy or proximal tubal occlusion should be considered before IVF.
• Lifestyle management and precautions
  • Prevent sexually transmitted infections (use condoms), have sexual partners tested and treated, and seek medical care early when symptoms occur.
  • Follow instructions for preventing infection and recovering after surgery.
  • If left untreated, there may be an increased risk of infertility, recurrent infections, chronic pelvic pain, and ectopic pregnancy.

Pre-Visit Checklist (Including Example Questions)

• Items to prepare/medical records to submit
  • A list of current medications (including prescription drugs, over-the-counter medicines, and supplements)
  • History of previous gynecologic surgeries and surgical records, if available
  • Results of previous tests (pelvic ultrasound, HSG, laparoscopic findings, blood tests, etc.)
  • Menstrual history (cycle and first day of the last menstrual period), whether pregnancy is desired, and the duration of trying to conceive
  • History of sexual activity and sexually transmitted infection testing, and records of signs of infection such as urinary symptoms, vaginal discharge, or fever
  • Timing, pattern, and severity of pain (pain diary)
• Materials useful to submit to the healthcare provider during the visit
  • Previous HSG or ultrasound images and reports
  • Notes on recent temperature and situations in which pain worsened

General Example Questions to Ask the Doctor

• "What are the advantages and disadvantages of the treatment options (medication and surgery), and what is the expected recovery period?"
• "What are the side effects of this medication?"
• "What is the prognosis? What is the likelihood of natural pregnancy?"
• "What lifestyle precautions should I take?"

Condition-Specific Example Questions

• "If I want to become pregnant after hydrosalpinx has been confirmed, should I have a salpingectomy first, or would it be better to begin preparing for IVF right away?"
• "Could you explain the success and recurrence rates of salpingostomy (recanalization) or reconstructive surgery?"

Additional Information

• If acute symptoms such as high fever, severe abdominal pain, chest symptoms, or excessive vaginal discharge occur, immediate medical attention is recommended.
• If you are planning infertility treatment, it is important to consult a gynecologist specializing in reproductive medicine (reproductive endocrinology and infertility clinic).
