Paraplegia following transurethral surgery

We have presented a case of paraplegia following spinal anaesthesia administered for a transurethral prostatic resection. Further investigation revealed a metastatic peridural compressive lesion at the level of T4. We have discussed some of the contributory factors involved, chiefly the lumbar puncture (perimedullary vascular engorgement, alterations in C.S.F. dynamics) and the possible role of intra-operative water intoxication (swelling of spinal cord cells).
