Vaginal prolapse mesh may effectively restore vaginal anatomy. The aim of this study was to investigate how the in vivo mesh position correlates to clinical outcomes.
Seventy-one women operated on using Uphold mesh for apical pelvic organ prolapse (POP-Q, C ≥ stage II) were examined 5 years after surgery by introital-perineal 2D ultrasound in a midsagittal plane at rest and Valsalva. The horizontal line and pubis symphysis were considered the reference for all measures. Ultrasound measures were statistically compared to clinical outcomes: POP-Q, Pelvic Floor Distress Inventory (PFDI-20) and subscales [Pelvic Organ Distress Inventory (PODI-6), and Urinary Distress Inventory (UDI-6)] and the VAS scale for pain.
Original mesh length was preserved by 86% and correlated to improved pain as estimated by VAS scale (r 0.321). Valsalva was associated with a lowering of the superior and inferior mesh margins by 7.3 and 6.1 mm, respectively (p < 0.001) but a reduction of total mesh length by only 1 mm (30.2 ± 5.2 to 29.2 ± 4.7 mm, p < 0.001). Mobility of the anterior vaginal wall (bladder neck and midurethra) at Valsalva was parallel to downward movement of the mesh inferior margin (r 0.346 and 0.314) but inversely correlated to total UDI-6 (r - 0.254 and - 0.263). Mobility of the midurethra was inversely correlated to bladder emptying (PFDI-20 Question 19, r - 0.245).
Five years after surgery, preserved original length of the mesh with apical support was correlated to improved anatomical and patient-reported outcomes. Mesh support to the vaginal apex was associated with improved bladder emptying and total urinary distress outcomes but not stress urinary incontinence.
