The needle, anal and catheter methods of performing simultaneous cystometry and pelvic floor electromyography were compared in 29 patients. Urethral sphincter electromyographic recordings consistently were satisfactory with a needle electrode, whereas the catheter surface electrode caused recording artifacts and was fragile. Anal sphincter electromyography was more reliable with a needle electrode than with an anal surface electrode.
