Abstract

Objectives: To define types of support failure after anterior compartment mesh placement and to investigate any association with predictors of recurrence.

Methods: This was a retrospective study on patients ≥ 3 months after anterior mesh placement. All patients underwent a standardized interview, clinical examination using the International Continence Society Pelvic Organ Prolapse Quantification system (ICS POP-Q) and three-dimensional/four-dimensional (3D/4D) translabial ultrasound. Mesh failure was defined as recurrence of anterior/central compartment prolapse seen on ultrasound. Failures were classified as anterior, global and apical. Their association with hiatal area on Valsalva maneuver and levator avulsion was tested.

Results: Three hundred and one patients were seen initially, of whom five were excluded because of missing data, leaving 296. Mean follow-up was 1.8 (range, 0.3–5.6) years. Mean age was 65 (range, 32–88) years. One hundred and thirty-nine (47%) women were fitted with a PerigeeTM mesh, 66 (22%) with an Anterior ProliftTM mesh and 91 (31%) with an Anterior ElevateTM mesh. Recurrent symptoms (lump/drag) were reported in 65 (22%), a recurrent cystocele was noted in 128 clinically (43%) and in 105 on ultrasound (35%). Avulsion was diagnosed in 117 patients (40%). Mean hiatal area on Valsalva was 33.3 (range, 14.1–60.0) cm2. Mesh failure was diagnosed in 112 patients (38%), comprising global failure in 81 (27%), apical failure in 23 (8%) and anterior failure in eight (3%). Apical and global failures were significantly associated with hiatal area, associations that remained after controlling for potential confounders.

Conclusions: Mesh failure, i.e. anterior or central compartment recurrent prolapse, was noted in 38% of patients on average 1.8 years after placement of anterior compartment mesh. Global and apical failures together constituted 93% of all mesh failures, both types of failure being significantly associated with hiatal area on Valsalva maneuver.
