Four-arm polypropylene mesh for vaginal vault prolapse-surgical technique and outcomes

Advanced vaginal vault prolapse (VVP) can occur rarely after any type of hysterectomy. Several types of procedures have been applied to correct this defect, but optimal management is still pending. The aim of this study was to describe the surgical technique and results of four-arm transvaginal mesh (FATVM) application for advanced VVP.

We followed up for 24 months, 160 patients with VVP > II vc (according to the Pelvic Organ Prolapse Quantification Scale (POPQ)), who underwent FAMTVM from 2014 to2017. FAMTVM was inserted with the anterior arms through the obturator foramens and the posterior arms through the ischiorectal fossas and sacrospinal ligaments. Clinical data were prospectively collected in a customized database and retrospectively analyzed. To assess QoL SF 36, KHQ and FSFI questionnaires were used. POPQ was employed to measure degree of VVP. Non-parametric tests (The Wilcoxon signed-rank test) were applied to verify statistical hypotheses.

According to SF 36, significant improvement was evident in almost all aspects of general QoL (PCS p = 0.002, MCS p = 0.01). KHQ showed statistically significant improvement in all domains. FSFI scores after surgery indicated significantly improvement in all domains of the questionnaire, apart from lubrication (p = 0.02). Intraoperative bladder injury occurred in 3.75 % (n = 6) of all cases. Five patients (3.1 %) complained of de novo stress urinary incontinence. VVP reoccurred in nine cases (5.6 %). Only two patients (1.25 %) saw mesh exposure after 6 months postoperative recovery.

We consider FAMTVM for VVP to be safe and effective. Hence, it applied as an optional treatment, especially in patients with contraindications to laparotomy and laparoscopy.
