In gynecological examinations, the detection of pelvic fluid accumulation is important for assessing women's pelvic health. Under normal circumstances, a small amount of fluid exists in the pelvis, serving to lubricate and protect the pelvic organs.
During a B-ultrasound examination, if the depth of the pelvic fluid accumulation is less than 10mm with clear boundaries and a regular shape, it is generally considered a normal physiological phenomenon, especially during menstruation or ovulation when the volume of pelvic fluid may increase to some extent. Generally speaking, fluid accumulation measuring less than 20mm is mostly physiological, with small volume that can usually be absorbed spontaneously, requiring no special treatment.
However, if the depth of the pelvic fluid exceeds 15mm, particularly if it has an irregular shape, unclear boundaries, or is accompanied by symptoms such as lower abdominal pain or fever, further examination is necessary to identify the cause and initiate treatment. Diagnostic methods include imaging examinations such as B-ultrasound, CT, and MRI, combined with clinical symptoms and laboratory test results for comprehensive evaluation. When necessary, puncture of the pelvis may be performed to extract the fluid for laboratory analysis.
If the fluid accumulation exceeds 25mm, it is highly likely to be pathological pelvic fluid, which must be taken seriously, and prompt medical examination and treatment are required.
