Summary
Brief summary (as posted)
The aim of this study is to estimate the incidence rate of obturator nerve reflex and leg jerking during Transurethral Resections of Bladder Tumors (TURBTs), evaluate the efficacy of obturator nerve block in the prevention of inadvertent muscle spasm, and to identify predictors for both the jerking reflex and successful nerve block.
