| Abstract: | The current study used topographic anatomy, distribution of arteries and nerves, sectional anatomy of the pelvis, computed tomography (CT) and ultrasonography examination to describe the canine pelvis and its organs. This study was conducted on twenty male and female baladi dogs, weighing 30–35 kg and aged between 1.5 and 2 years. The pelvis dorsal boundary appeared long and reached to the level of the third caudal vertebra. The vesicogenital pouch in the female extended further caudally than the rectogenital pouch while in the male the two pouches were at the same level and extended to the level of the first sacral vertebra. The plexus lumbosacralis formed from the ventral branches of the last three lumbar nerves and the first three sacral nerves. The obturator nerve arose from the ventral branches of the fifth and sixth lumbar nerves. We developed an anatomical atlas of the pelvis of both sexes of the dog using CT scans compared to anatomical sections. Our study is the first research on the pelvis in both sexes of the dog to compare sagittal CT scan data to sagittal anatomical sections. In the CT slices, the prostate appeared homogenous, relatively hypodense presenting with a soft tissue density. It appeared oval in the longitudinal sections and elliptical to round at the cross sections. It was situated on the floor of the pelvic cavity or the pelvic brim depending on its size. The present study is also the first to describe the fascia diaphragmatic pelvis. |
