|ACH Surgeons Begin Clinical Trial to Evaluate Xiao Procedure|
All Children’s has begun a clinical research trial of a surgical procedure that holds promise for treating neurogenic bladder in children with spina bifida or spinal cord injuries.
The three-year, blinded, IRB-approved study will involve children with spina bifida or spinal cord injuries. It began in mid-March with eight children who underwent surgery. Seven were spina bifida patients who were already undergoing surgery for spinal cord detethering; half also underwent the “Xiao procedure” that All Children’s physicians are evaluating. The eighth patient, whose bladder dysfunction was a result of surgery during his infancy to remove a spinal cord tumor, had surgery specifically to undergo the Xiao procedure.
The Xiao procedure was developed by Chuan-Guo Xiao, M.D., Chairman of the Department of Urology at Union Hospital, Tongji Medical College, People’s Republic of China. The Xiao procedure, developed during NIH-funded research in the U.S. and China, has been performed on some 1,500 adults and children in the People’s Republic. Pediatric urologist Yves Homsy, M.D. became interested in the procedure last year after meeting Professor Xiao at an International Children’s Continence Symposium in Hong Kong.
Dr. Homsy and pediatric neurosurgeons Gerald Tuite, M.D. and Luis Rodriguez, M.D., subsequently visited Professor Xiao to review his results and learn the technique. They are working together in the clinical research trial at ACH.
The Xiao procedure involves an intradural re-routing of lumbar to sacral nerves to provide a new pathway for voluntary bladder emptying. After the “skin-CNS-bladder” reinnervation procedure, the bladder and bowels are activated when the patient vigorously scratches a spot on the thigh. Following surgery, neurological healing and nerve regeneration take at least eight months.
