AbstractStimulation of obturator nerve during transurethral electroresection causes violent adductor muscle contraction, and is a major cause of inadvertent bladder perforation. General anesthesia with muscle relaxants is often required when the bladder tumor is in the area where the obturator nerve passes in close proximity to the inferolateral bladder wall. Recently obturator nerve block under spinal anesthesia during transurethral surgery have been reported in several papers, but the blockade is not completely reliable. Obturator nerve block using electrostimulator (neutracer) and insulated electroneedle (pole needle) was performed in 25 patients with bladder tumors during transurethral electroresection from October 1980 to December 1981. We herein describe the technique and results of local obturator nerve blockade. Use of neutracer and pole needle makes the obturator nerve block a completely reliable, safe and easy procedure.
