According to the Better Health Channel, the primary cause of pus in the Fallopian tube is salpingitis, which is sometimes called pelvic inflammatory disease, or PID. Salpingitis is an inflammation of the Fallopian tubes caused by a bacterial infection.
Although salpingitis is sometimes referred to as pelvic inflammatory disease, PID is actually a blanket term that refers to several types of infections of certain parts of the female reproductive system, including the ovaries and uterus. Salpingitis refers specifically to an inflammation or infection of the Fallopian tubes. Better Health Channel notes that nearly all cases of salpingitis are triggered by a bacterial infection, which can include sexually transmitted diseases such as chlamydia and gonorrhea.
Inflammation stimulates excess fluid secretion or pus to collect within the Fallopian tubes. Because bacteria spread, both Fallopian tubes typically end up with an infection. Salpingitis requires prompt treatment or else the infection may cause permanent damage to the Fallopian tube and lead to an ectopic pregnancy, tubo-ovarian abscess or infertility. It is one of the most common causes of female infertility.
According to KidsHealth, some of the symptoms of salpingitis and PID include pain during urination, more frequent urination, abnormal vaginal discharge with an unusual color or smell, lower abdominal pain that often occurs on both sides, lower back pain, fever, chills, nausea, vomiting, diarrhea, irregular menstrual bleeding, fatigue and pain during intercourse. Better Health Channel notes that these symptoms are most likely to present themselves after a menstrual period.
The primary way to prevent salpingitis or PID is to practice safe sex, according to KidsHealth. However, The Better Health Channel notes that bacteria can enter the female reproductive system through several other means. These include miscarriage, abortion, childbirth, insertion of an intra-uterine device and appendicitis.
The Better Health Channels explains that treatment options include antibiotics, which might require hospitalization for intravenous administration. If the infection resists antibiotic treatment or complications occur, surgery may be required.
