How many mm is normal for pelvic effusion?

How many mm of pelvic fluid is normal?

1. Pelvic effusion is caused by inflammation, that is, exudation from chronic pelvic inflammation. A few cases are caused by ruptured ectopic pregnancy, corpus luteum rupture, pelvic abscess, chocolate cyst, and ovarian cancer. Those caused by acute or chronic pelvic inflammatory disease are often accompanied by bilateral or unilateral lower abdominal pain, lumbar pain, etc.

2. The normal value of pelvic effusion should be less than 10 mm. Physiological pelvic effusion is less than 10 mm. During the menstrual period and the first few days after the menstrual period, some menstrual blood may flow back along the fallopian tube to the pelvic cavity, and ultrasound will show a small amount of effusion. Or after ovulation, follicular fluid will flow into the pelvic cavity along with the ruptured follicles. Generally, the amount is very small, and a slightly larger amount can be seen under ultrasound. These two types can disappear naturally, no treatment is required, and will not cause harm to the body.

3. Pelvic effusion often occurs in the lower part of the pelvic cavity, such as the uterine rectal pouch. B-ultrasound is a commonly used and effective means of examination in gynecology, which can accurately determine the amount of effusion. It can be determined in detail whether it is normal effusion or abnormal effusion by combining medical history, symptoms and physical signs. If it is confirmed to be abnormal effusion, the cause of the effusion must be determined, and removing the cause is the key.
