بزل الردبة المستقيمية الرحمية

Culdocentesis is a medical procedure involving the extraction of fluid from the rectouterine pouch (pouch of Douglas) posterior to the vagina through a needle. It can be one diagnostic technique used in identifying pelvic inflammatory disease (in which case purulent fluid will be extracted) and ruptured ectopic pregnancies that cause hemoperitoneum.
