IntroductionRetroperitoneal space of the true pelvis differs from retro-peritoneal areas elsewhere in the abdomen by the presence of the sub-peritoneal areolar (cellular) connective tissue.

We can recognize about 6 We can recognize about 6 retroperitoneal spaces. retroperitoneal spaces.

Cardinal lig

The subperitoneal area of the pelvis is partitioned

into potential spaces by the various organs & their re-

spective fascial coverings, and by the selective thick-

enings of the endopelvic fascia into ligaments and
