Changes in levator ani muscle after vaginal hysterectomy and prolapse repair using the Total Prolift procedure

Abstract

Objective To assess changes in the levator plate angle (LPA), anteroposterior length of the levator hiatus (H-line), and pelvic floor descent (M-line) after vaginal hysterectomy and prolapse repair using the Gynecare Prolift Total Pelvic Floor Repair System. Methods Before and after the intervention, 20 women with pelvic floor prolapse underwent dynamic magnetic resonance imaging in supine position during the Valsalva maneuver to measure the LPA, H-line, and M-line. Paired t tests were performed and Pearson correlation coefficients calculated from values obtained using the pelvic organ prolapse quantification system. Results After the intervention the LPA was smaller (46.92° vs 55.39°, P < 0.05), the H-line was shorter (53.70 cm vs 60.46 cm, P < 0.05), and the M-line was shorter (19.58 cm vs 25.27 cm, P < 0.05). Conclusion These changes suggest an efficient reconstruction and reinforcement of the pelvic floor after the surgery.
