Success Rate of Transobturator Paravaginal Repair for Pelvic Organ Prolapse

Abstract

Aim: To evaluate the short-term anatomical and functional outcomes of transobturator paravaginal repair in women with pelvic organ prolapse (POP). Methods: A retrospective cohort study was conducted in 42 patients with stage 3 or higher cystocele and paravaginal defects treated between 2023 and 2024. The procedure was performed using the Siriraj Urogynecology Mesh Kit trocar set without any mesh material. The primary outcome was anatomical success (POP-Q Ba ≤ 0) at 6 months postoperatively. Secondary outcomes included perioperative data, complications, and short-term morbidity, which were recorded and analyzed. Results: Forty-two patients were enrolled. Mean age was 68.71 ± 9.20 years. The anatomical success rate at 6 months was 83.3% for the anterior compartment (95% CI: 68.6–93.0) and 92.0% for the apical compartment (95% CI: 83.8–99.4) at 6 months postoperatively. Mean ICIQ-VS scores improved from 23.2 ± 8.9 to 7.1 ± 8.3 (p < 0.001), and quality-of-life scores improved from 7.0 ± 2.8 to 1.1 ± 2.5 (p < 0.001). POP-Q points Ba and C showed significant improvement (p < 0.001). Higher BMI and advanced POP stage were significantly associated with recurrence. Conclusions: Transobturator paravaginal repair demonstrated favorable short-term anatomical outcomes for both anterior and apical compartments with minimal morbidity. Although these early results are promising, longer follow-up is necessary to confirm long-term durability and recurrence rates.
