The multifilament polypropylene tape erosion trouble: tape structure vs surgical technique. Which one is the cause?

摘要

This study was designed to clarify whether the structure of multifilament tape or the surgical technique is associated with vaginal erosions. Patients were randomized into two groups: in group 1, formed from the patients who were operated with the technique "setting the tape loosely leaving a scissor tip gap between the tape and the urethra," and in group 2, formed from the patients who were operated with the technique "setting the tape actually touched the urethra and covering the tape by the adjacent pubocervicovaginal fascia with the aid of a suture." After 4-year follow-up, it was found that the erosion rate was very high in group 1 (13.6%). We conclude that the high erosion rate seen in multifilament tapes is associated with the surgical technique that is used, not the structure of the multifilament tape.
