Dynamic Interaction Involved in the Tension-Free Vaginal Tape Obturator Procedure

Purpose: We explored the static and dynamic morphological characteristics of the tension-free vaginal tape obturator procedure by ultrasound cystourethrography. Materials and Methods: From July 2005 to December 2006, 98 consecutive women who had undergone the tension-free vaginal tape obturator procedures alone or with concomitant pelvic surgery were evaluated. Preoperative and postoperative morphological assessments of lower urinary tract and tension-free vaginal tape obturator procedure tape were performed by introital ultrasound. Results: The resting and straining bladder neck angles as well as the resting tape angle gradually increased postoperatively while the resting bladder neck distance and total urethral length decreased. The vector of the tension-free vaginal tape obturator procedure tape was significantly correlated with the resting tape distance (r = 0.55, p
