Aims: To compare the surgical outcomes of conventional surgeries with or without concomitant transobturator vaginal mesh (TVM) for ≥Stage 3 pelvic organ prolapse (POP).
Methods: We retrospectively investigated 166 women who received conventional surgery including vaginal total hysterectomy, modified McCall culdoplasty, and AP-repair (conventional group) and 98 women with concomitant TVM (mesh group). Follow-up at 3, 12, and 24 months comprised symptom interview, pelvic examination, and ultrasound assessments. The primary outcome was anatomical success defined as ≤Stage 1 POP. Secondary outcomes were subjective symptoms, ultrasound manifestations, and complications.
Results: Both groups showed improvements in functional and anatomical outcomes after operations. Compared with the conventional group, the mesh group had higher rates of de novo stress urinary incontinence (SUI) at 3-month (3.6% vs 19.4%; P < .001), 12-month (3.7% vs 26.4%; P < .001), and 24-month (2.4% vs 21.4%; P = .001) follow-up, a higher POP-C point (-7.3 ± 0.7 cm vs -7.6 ± 0.6 cm; P < .001) at 3-month follow-up, a smaller straining bladder neck angle indicating a more cranioventral straining bladder neck position (117 ± 25° vs 102 ± 20°; P < .001) at 3-month follow-up, and a less bladder neck mobility at 3-month (19 ± 24° vs 8 ± 14°; P = .002) and 12-month (26 ± 18° vs 12 ± 15°; P = .003) follow-up.
Conclusions: Concomitant TVM is associated with a higher rate of de novo SUI, more cranioventral straining bladder neck position, and less bladder neck mobility.
