The rectovesical pouch is the pocket that lies between the rectum and the bladder in males in humans and other mammals. It is lined by peritoneum.
Structure
[edit]The rectovesical pouch is a space between the rectum and the bladder in men.[1] It lies above the seminal vesicles.[2] It is lined by peritoneum and at its base is the rectoprostatic fascia (Denonvillier's fascia). When a man is upright or supine, it is the lowest part of his peritoneal cavity.[3] It may contain parts of the ileum (lower small intestine) and the sigmoid colon.[2]
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. After a hysterectomy in women, the remaining peritoneum may be referred to as a rectovesical pouch.[4]
Clinical significance
[edit]When a man is upright or supine, the rectovesical pouch is the lowest part of his peritoneal cavity.[3] Because of this, peritoneal fluid and other fluids that enter the peritoneal cavity, including ascites, blood and pus, tend to collect in this pouch.
