title: TOT does not affect the urethral sphincter innervation: a pilot study.
abstract: OBJECTIVE
  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.
