rectovesical pouch
The deepest part of the peritoneal cavity in males, located between the rectum and bladder where fluid collections commonly occur.
Full Definition
The rectovesical pouch is an anatomical landmark crucial in laparoscopic surgery, representing the most dependent portion of the male peritoneal cavity. Located between the rectum posteriorly and the bladder anteriorly, this pouch is where pathological fluid collections, blood, or irrigation fluid naturally gravitates during surgery. In laparoscopic procedures, surgeons must carefully inspect this area for bleeding, fluid accumulation, or pathology. The female equivalent is the pouch of Douglas (rectouterine pouch). Proper identification and examination of the rectovesical pouch is essential for complete laparoscopic exploration and ensuring no retained fluid or missed pathology.
Usage
Usage note: Male-specific anatomical term; use 'pouch of Douglas' for female patients.
