Modified needle route for potential reduction of the trans-obturator inside-out-related thigh pain: a cadaveric study

To evaluate the anatomical aspects and relations of a modified tissue passage with the tension-free vaginal tape obturator (TVT-O) needle, designed for the purpose of reduction of the thigh pain, related with this anti-urinary incontinence operation. The distances between the modified TVT-O surgically inserted needle and obturator nerve branches were measured in fresh cadaver. The introduced surgical needle caused no trauma to any of the adjacent cadaveric organs, and the distances between the surgical needle and the obturator nerve branches was 4 cm. The modified TVT-O needle route is shown to be safe and remote from the obturator nerve branches, thus conduction of a clinical study for evaluation of related pain reduction is recommended.
