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.
