Pelvic Irrigation

The pelvis contains numerous structures in a small space. The female pelvis is more complex because of the intracavitary presence of the reproductive organs, different from what is found in the male pelvis. The functionality of these organs, especially the uterus during pregnancy, requires greater blood support from the female pelvis. The lymphatic drainage system is formed by transparent canaliculi along the retroperitoneal fat and is closely connected to the venous system. Along the canaliculi are found ganglion structures containing accumulations of lymph cells known as lymph nodes. The cluster of lymphatics and nodes responsible for loco-regional drainage is called the lymphatic chain. The main vascular structures of the pelvis are found in the retroperitoneum, adjacent to the posterolateral walls. The venous system is deeper and presents more anatomical variations than the arterial one. The abdominal aorta and vena cava, although not in the pelvis, are primarily responsible for pelvic irrigation.
