Unique Vesico-obturator Ligament and Its Functional and Surgical Importance

The present report is about a unique vesico-obturator ligament observed in an adult male cadaver during dissection classes. The ligament extended from the inferolateral surface of the urinary bladder to the fascia covering the obturator internus. It was conical in shape and contained some veins running from the thigh to the vesical venous plexus. The obturator nerve and vessels had a normal course. Possibly, this is the first report on this type of ligament, and it might interfere in the normal micturition process and might also result in bleeding during various surgical procedures in and around the obturator foramen.
