BESCES is a study that aims to explore the feasibility of intraoperative brief epidural electrical stimulation (ES) for patients undergoing routine decompression for cauda equina syndrome. In consenting patients, brief ES will be applied using a CE-marked SCS trial kit once sufficient decompression is achieved. In participants who do not recover function following decompression, brief post-op ES will be applied to see if can facilitate micturition and/or removal of the catheter. The study will assess: The feasibility of intervention. If brief ES can facilitate conduction in residual neurons. If brief ES can facilitate neuronal recovery
