Objectives: To assess the efficacy and safety of spinal anesthesia combined with obturator nerve block (ONB) for transurethral resection of bladder tumor. Subjects and methods: A prospective study was carried out on 10 patients who underwent spinal anesthesia combined with ONB using nerve stimulation for transurethral resection of bladder tumor. Quality of anesthesia, violent adductor contraction and inadvertent bladder perforation as well as side effects were monitored. Results: All patients had an excellent quality of anesthesia, distance from skin to obturator nerve was 2.6 ± 1.4 cm on everage, 9 patients were absent of leg jerking. Side effects included shiving in 2 cases, hypotension in 1 case and bradycardia in 1 case. Conclusion: Combination of spinal anesthesia and ONB provided good effective anesthesia for transurethral resection of bladder tumor: adductors muscle spasms were absent in 90%, side effects were transient and mild. * Key words: Bladder tumor; Spinal anesthesia; Obturator nerve block; Transurethral resection of bladder tumor.
