Over 500 obturator nerve blocks in the lithotomy position during transurethral resection of bladder tumor

摘要

Introduction and aim of the studySpinal anesthesia for transurethral resection of bladder tumor (TURB) does not prevent unintended stimulation of the obturator nerve when electroresection is performed on the lateral wall of the bladder. It results in muscle contraction of the adductor muscles of the thigh, which may lead to perforation of bladder wall with the resectoscope loop. The aim of the study was to assess the efficacy and safety of obturator nerve block (ONB).
