Medium-term outcomes for primary native tissue reconstructive surgeries with and without transobturator vaginal meshes in stress continent women with stage 3 or higher pelvic organ prolapse.

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.
