rectovesical pouch
Peritoneal reflection between the rectum and bladder in males, anatomically analogous to the pouch of Douglas in females.
Full Definition
The rectovesical pouch is the most dependent portion of the peritoneal cavity in males, formed by the peritoneal reflection between the rectum posteriorly and the bladder anteriorly. While this term is primarily relevant in male anatomy, it appears in gynecologic oncology literature when discussing anatomical relationships and surgical approaches, particularly in cases involving extensive pelvic disease or when describing peritoneal spread patterns. Understanding this anatomical landmark is important for gynecologic oncologists performing comprehensive staging procedures and when interpreting imaging studies that may show peritoneal disease extending beyond typical female pelvic anatomy.
Usage
Usage note: Primarily used when discussing male pelvic anatomy or extensive peritoneal disease patterns.
