My 9 year old son had spine surgery to correct his scoliosis. Immediately following surgery he had severe right leg/ right foot/right buttocks pain. He did not have this pain prior to surgery. This pain resolved after 8 weeks.He had normal bladder function prior to surgery. Following surgery his bladder does not contract and he now requires catheterization. He had a CT mylogram 7 months after surgery which showed a screw pressing on S2. He had revision of that screw 7 weeks ago. No improvement in bladder function. Just wondering if anyone lost bladder function following spine surgery and if they regained it.
