Hydrosalpinx
A hydrosalpinx is a condition where a fallopian tube becomes blocked and fills with fluid. It often results from previous infections, pelvic inflammatory disease, or surgery, and can cause pelvic pain or fertility problems. Some people may have no symptoms at all. Treatment focuses on managing symptoms and improving fertility, which may include surgery or assisted reproductive techniques.

The Fallopian Tubes
The fallopian tubes are thin, flexible tubes that connect the ovaries to the uterus, allowing eggs to travel from the ovary to the womb for fertilisation. Normally, they are open and have a delicate lining that helps the egg move along.
A hydrosalpinx occurs when one or both fallopian tubes become blocked and fill with fluid. This fluid accumulation causes the tube to swell and can interfere with fertility by preventing the egg and sperm from meeting or affecting implantation. The condition usually develops as a result of prior infections, inflammation (for example, from pelvic inflammatory disease), endometriosis, or scarring from previous surgery. Chronic inflammation can damage the tube’s lining, making it less able to transport eggs effectively.
Although hydrosalpinx itself may not cause obvious symptoms in some people, it can sometimes lead to pelvic discomfort, abnormal bleeding, or an increased risk of ectopic pregnancy. It is most commonly identified when investigating infertility.
Understanding Hydrosalpinges
A hydrosalpinx often does not cause noticeable symptoms, especially in its early stages. Many people only discover it when undergoing investigations for infertility or during imaging for another pelvic concern. However, when symptoms do occur, they can include:
- Pelvic discomfort or pain: A dull, persistent ache in the lower abdomen or pelvis, sometimes worsened during menstruation.
- Abnormal vaginal discharge: Occasionally, a watery or unusual discharge may be noticed.
- Infertility: Difficulty conceiving is often the first sign that prompts investigation.
- Menstrual irregularities: Some may experience irregular or heavier periods, though this is less common.
- Occasional bloating or fullness: A sense of pressure in the lower abdomen if the tube is significantly enlarged.
Even if symptoms are mild or absent, it is important to investigate if you are experiencing fertility issues, as untreated hydrosalpinx can reduce the chances of successful conception.
Causes and Risk Factors
Hydrosalpinx occurs when a fallopian tube becomes blocked, often leading to fluid accumulation within the tube. The main underlying causes include:
| Pelvic infections | Previous pelvic inflammatory disease (PID) caused by sexually transmitted infections like chlamydia or gonorrhea can damage the fallopian tubes. |
| Previous surgery | Abdominal or pelvic surgery, including for ectopic pregnancy, endometriosis, or appendicitis, can cause scarring that blocks the tubes. |
| Endometriosis | Growth of endometrial tissue outside the uterus can affect the tubes and lead to blockage. |
| Tubal ligation complications | Rarely, previous sterilisation procedures can result in fluid buildup. |
Diagnosing Hydrosalpinges
A hydrosalpinx may be suspected in women with fertility difficulties or pelvic pain, and is sometimes found incidentally on imaging. Diagnosis typically involves a combination of clinical assessment and imaging tests.
| Ultrasound | A transvaginal pelvic ultrasound is usually the first-line imaging test. It can identify fluid-filled, dilated fallopian tubes and assess for other pelvic conditions. Ultrasound can sometimes distinguish hydrosalpinx from other cystic structures in the pelvis. |
| Hysterosalpingography (HSG) | This X-ray test involves injecting contrast into the uterine cavity and fallopian tubes to assess their patency. Blocked or dilated tubes may indicate hydrosalpinx. |
| MRI Scan | Reserved for cases where ultrasound findings are unclear or additional anatomical detail is needed. MRI can provide a more detailed view of the fallopian tubes and surrounding structures. |
Treatment Options
Management of hydrosalpinx depends on symptoms, severity, and whether fertility is a concern:
| Observation | If the hydrosalpinx is small and not causing symptoms, sometimes careful monitoring is all that is needed. |
| Medical management | Pain or mild inflammation may be managed with anti-inflammatory medications. However, medications do not correct the blocked or dilated tube. |
| Surgical options | Salpingectomy: Removal of the affected fallopian tube is often recommended for women considering IVF, as it can improve success rates. Salpingostomy or tuboplasty: In selected cases, surgical opening or reconstruction of the tube may be attempted, though success rates vary. |
| Fertility considerations | Hydrosalpinx can impair natural conception and IVF outcomes. Referral to a fertility specialist is important if conception is desired. |
The choice of management is individualized, taking into account symptoms, reproductive plans, and overall pelvic health.
