Dissection of male pelvis from a lateral approach
Close-up view of ureterovesical junction
The central area of the specimen shown in the previous photograph is viewed here to display in more detail the structures that lie immediately adjacent to the ureterovesical junction. The smooth muscle and fibrous tissue that surrounds the pelvic plexus and forms the lateral ligament of the bladder has been preserved. Areolar tissue has been removed from other parts of the specimen.

2 . Upper pointer: Ductus deferens Lower pointer: Parietal peritoneum (external aspect)
3 . Obturator nerve
4 . Upper pointer: Obturator artery (cut off) Lower pointer: Superior vesical artery
5 . Urinary bladder
6 . Ilium (cut away)
7 . Middle vesical artery
8 . Inferior vesical artery
9 . Vesical veins (cut off)
10 . Ureter
11 . Pelvic ganglion
12 . Strands of superior hypogastric plexus (embedded in fibrous tissue and smooth muscle of pelvic fascia)
13 . Sciatic nerve (retracted)
14 . Inferior gluteal artery
