Anatomical terminology

In women, the uterus lies between the rectum and the bladder. Therefore, women do not have a rectovesical pouch, but instead have a rectouterine pouch and vesicouterine pouch.

Structure

The rectovesical pouch is a space between the rectum and the bladder in men.[1] It is lined by peritoneum and at its base is the rectoprostatic fascia (Denonvillier's fascia).

Clinical significance

When a man is upright or supine, the recto-vesical pouch is the lowest part of his peritoneal cavity. Because of this, peritoneal fluid and other fluids that enter the peritoneal cavity, including ascites, blood and pus, tend to collect in this pouch.
