Mesh retraction correlates with vaginal pain and overactive bladder symptoms after anterior vaginal mesh repair

The aim of the present study was to determine possible correlations between mesh retraction after anterior vaginal mesh repair and de novo stress urinary incontinence (SUI), overactive bladder (OAB), and vaginal pain symptoms.

One hundred and three women with symptomatic prolapse of the anterior vaginal wall, stages 3 and 4 based on the Pelvic Organ Prolapse Quantification (POP-Q) system, underwent Prolift anterior™ implantation. At a 6-month follow-up, the patients were interviewed for de novo SUI, OAB, and vaginal pain, and underwent an introital/transvaginal ultrasound examination to measure the mesh length in the midsagittal plane.

Mesh retraction was significantly larger in a subgroup of patients (n = 20; 19.4 %) presenting de novo OAB symptoms on the follow-up assessment compared with those without this complication (5.0 cm vs. 4.3 cm; p < 0.05). Mesh retraction was also significantly larger in a subgroup of patients (n = 23; 22.3 %) reporting postoperative vaginal pain compared with the women who did not report any postoperative vaginal pain (5.3 cm vs. 4.2 cm; p < 0.01). A significant correlation was found between mesh retraction and the severity of vaginal pain (R = 0.4, p < 0.01). Mesh retraction did not differ between patients with de novo SUI symptoms and those without this complication.

Mesh retraction assessed on ultrasound examination after anterior vaginal mesh repair may correlate with de novo OAB symptoms and vaginal pain.
