Introduction and hypothesis: To exclude a neuromuscular denervation damage due to prosthetic mini-invasive surgery using transobturator tape (TOT) by pre and postoperative electromyography (EMG) of the striated urethral sphincter. Methods: Seventeen women with SUI were enrolled by urogynecologic and urodynamic examination. Each of them underwent EMG of striated urethral sphincter performed by 25-mm concentric needle that was put in as far as 5 mm inside internal urethral sphincter. Amplitude and duration of EMG potentials were measured during caught, maximal contraction, and at rest. Four months after TOT treatment women underwent EMG. Results: The mean amplitude of EMG potentials does not show significant statistical differences between pre- and post-TOT (P=NS). The duration of potentials, instead, changed between pre and posttreatment only during the maximal contraction test (P≤0.05). Conclusions: TOT prosthesis surgery, avoiding denervation and devascularization of pelvic structures does not produce damage of the urethral sphincter. © The International Urogynecological Association 2011.

Abstract

Introduction and hypothesis: To exclude a neuromuscular denervation damage due to prosthetic mini-invasive surgery using transobturator tape (TOT) by pre and postoperative electromyography (EMG) of the striated urethral sphincter. Methods: Seventeen women with SUI were enrolled by urogynecologic and urodynamic examination. Each of them underwent EMG of striated urethral sphincter performed by 25-mm concentric needle that was put in as far as 5 mm inside internal urethral sphincter. Amplitude and duration of EMG potentials were measured during caught, maximal contraction, and at rest. Four months after TOT treatment women underwent EMG. Results: The mean amplitude of EMG potentials does not show significant statistical differences between pre- and post-TOT (P=NS). The duration of potentials, instead, changed between pre and posttreatment only during the maximal contraction test (P≤0.05). Conclusions: TOT prosthesis surgery, avoiding denervation and devascularization of pelvic structures does not produce damage of the urethral sphincter. © The International Urogynecological Association 2011.
