Good answer, Scott! A "void" is a scary concept. Truthfully, the whole prospect can be stressful. Joelsmith, my jpouch had adhered to my bladder after four years. It took an extra hour and a half in surgery to unattach it. I had no issues afterward but was made aware of the risks by my surgeon. You have to just want your jpouch out enough to go with the trust and skill of your surgeon. Wishing you the absolute best of luck, the speediest recovery possible, and no more feeling drained from your jpouch! Come here with any concerns. We've been through this and are here for you.
