The posterior fornix of the vagina is clinically important because it is directly related to which structure?

• A Urinary bladder
• B Urethra
• C Rectosigmoid junction
• D Pouch of Douglas ✓

Explanation

The posterior fornix is the deepest part of the vagina and is separated from the pouch of Douglas (rectouterine pouch) only by the vaginal wall and peritoneum. This allows clinical access for culdocentesis and drainage of pelvic collections. The bladder and urethra are anterior, and the rectosigmoid is too high to be directly related to the fornix.
