Conclusion

This study revealed that patients with NMIBC localized on lateral wall of the bladder who received an obturator nerve blockade combined with spinal anaesthesia had a significantly increased RFS, increased rate of complete resection and adequate detrusor muscle sampling. Although we could not observe statistically significant difference in terms of perioperative complication rates, patients underwent obturator nerve blockade combined with spinal anaesthesia had lower clinically significant peroperative complication rates. The obturator nerve blockade combined with spinal anaesthesia also contributes to the correct staging of patients with lateral wall localized NMIBC, which plays a critical role in their subsequent treatment.
