On either side of the bladder the peritoneum shows a depression, named the paravesical fossa (Fig. The lateral borders extend from the ureters to the vertex, and from them the peritoneum is carried to the walls of the pelvis. The superior surface is triangular, bounded on either side by a lateral border which separates it from the inferior surface, and behind by a posterior border, represented by a line joining the two ureters, which intervenes between it and the fundus. The peritoneum is carried by it from the vertex of the bladder on to the abdominal wall to form the middle umbilical fold. ![]() The vertex is directed forward toward the upper part of the symphysis pubis, and from it the middle umbilical ligament is continued upward on the back of the anterior abdominal wall to the umbilicus. 1152) is triangular in shape, and is directed downward and backward toward the rectum, from which it is separated by the rectovesical fascia, the vesiculæ seminales, and the terminal portions of the ductus deferentes.
