A Different Obturator Nerve Block Approach Using Nerve Stimulation Device Under Fluoroscopy Guidance in the Transurethral Resection of Lateral Bladder Wall Tumors
Journal Title: The Medical Bulletin of Haseki - Year 2021, Vol 59, Issue 2
Abstract
Aim: This study aims to define the efficacy and safety of a different obturator nerve block technique using fluoroscopy and nerve stimulation device during transurethral resection of bladder tumor (TUR-BT). Methods: Sixty patients with lateral bladder wall tumors who had TURBT were retrospectively analyzed for the formation of obturator reflex. Thirty patients received spinal anesthesia (SA) and 30 patients received SA combined with an obturator nerve block (ONB). ONB was performed in the lithotomy position. A percutaneous needle was advanced to the superolateral portion of the obturator foramen under fluoroscopic guidance. The nerve was localized with a nerve stimulation device and 5 mL of 2% prilocaine was injected to perineural area. Additionally, the tumor base was marked intravesically by resectoscope with fluoroscopy and 5 mL of %2 prilocaine was administered to nearby tissue. Obturator reflex formation reflex-related related complications were compared between the two groups. Results: The results of our study yielded a statistically significant difference in the favor of ONB compared to SA alone for the occurrence of obturator reflex (13% vs 43%, p=0.020), bladder perforation (0% vs 23.3%, p=0.002), and absence muscle tissue in the pathological specimen (10% vs 40%, p=0.01). Conclusion: ONB with the help of a nerve stimulation device, directed by fluoroscopy is effective to prevent obturator reflex and related complications.
