First, an intravenous line will be placed, generally in your hand. We will then bring you to the operating room and place several monitors on you, such as a heart, blood pressure and a pulse. These will enable us to monitor your vital signs throughout the procedure. Following placement of the monitors we will begin to give you some intravenous medication in order to decrease anxiety, as well as provide you with some pain relief.
You will then be placed in the prone position (on your stomach). The physicians will then use X-ray guidance to aid in appropriate placement of the medication. After clearing a small patch of your skin, a local anesthetic is injected into the skin to decrease any pain associated with performance of the procedure. The medication will then be administered through a needle near your hip bones on both sides. The procedure itself usually lasts 10 to 15 minutes. Occasionally, patients describe a very transient recurrence of their pelvic pain during administration of their medication. This is viewed as a reassuring sign that the medication is going to the right place, and the sensation usually disappears very quickly.
