Follow the peritoneal covering of the urinary bladder posteriorly, as it drops inferiorly into the space between the posterior surface of the urinary bladder and the anterior surface of the rectum. This space, the rectovesical pouch [the tip of the probe lies in this space] is shallow and extends inferiorly to the level of the ureters entering the urinary bladder. The rectovesical pouch is the lowest point in the male peritoneal cavity (Figure 44.1). Lateral reflections of the peritoneum from the rectum onto the posterior wall of the pelvis form pararectal fossae. Identify pararectal fossae on both sides of the rectum.
