    Journal: Int J Gynaecol Obstet; 2009 Jul; 106(1):53-6. PubMed ID: 19358987.
    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 degrees vs 55.39 degrees, 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.
