Impact of obturator nerve block on the short-term recurrence of superficial bladder tumors on the lateral wall.

Abstract

Follow-up periods (range, 19 to 41 months for group 1 and 19 to 39 months for group 2) and overall recurrence rates (group 1, 27.8% and group 2, 18.8%) were also found to be similar. Mean time to recurrence was significantly higher in group 2 (15 ± 5.5 months) than in group 1 (7.8 ± 4.5 months) (P = .009) CONCLUSION: ONB employed in addition to spinal anesthesia in TUR-BT involving the lateral wall can prolong time to recurrence and increase the chance to lengthen disease-free survival in low-risk superficial bladder tumors.
