INTRODUCTION: In this prospective randomized controlled study, we investigated the efficacy of obturator nerve block (ONB) on adductor muscle @entity2473 and related short-term outcomes and complications in @entity1 who underwent transurethral resection of lateral wall-located @entity150 (TURBT). METHODS: Between July 2014 and February 2015, 70 @entity1 scheduled to undergo TUR of lateral bladder wall @entity5 were enrolled in the study. All @entity1 were preoperatively evaluated by cystoscopy and imaging tools and selected according to localized @entity5 on the lateral bladder wall. @entity1 were randomly allocated to Group SA (35 @entity1 who underwent only spinal anesthesia) and Group ONB (35 @entity1 who underwent spinal anesthesia combined with ONB by the nerve stimulator). An independent observer, blinded to the approach, evaluated the obturator signs, including adductor muscle contraction, @entity1494 , and completeness of the resection during the TURBT procedure. RESULTS: The differences between groups regarding mean operation time, @entity5 size, and number were not statistically significant (p > 0.05). Adductor muscle contraction was detected in 40% of @entity1 in Group SA and 11.4% in Group ONB. This difference was statistically significant (p = 0.021). @entity1494 was detected in 2 @entity1 in Group SA, whereas no perforation was observed in Group ONB. There was no case of severe @entity548 in both groups. CONCLUSIONS: We found that ONB performed after spinal anesthesia was effective in preventing @entity3816 due to adductor muscle @entity2473 while performing TURBT. Our study limitations include its small sample size, since we only enrolled @entity1 with primary lateral wall-localized @entity150 . Also, we excluded @entity1 who underwent @entity162 .
