Intermediate- to long-term outcomes of transvaginal mesh for treatment of Asian women with pelvic organ prolapse.

Short-term follow-up analyses suggest that transvaginal mesh has limited application for pelvic organ prolapse (POP) treatment. This study evaluated the intermediate- and long-term outcomes of transvaginal mesh surgery.

This retrospective study included all women who underwent transvaginal mesh surgery in one urogynaecology centre. Inclusion criteria were women with stage III/IV POP, age ≥65 years, and (preferably) sexual inactivity. Concomitant sacrospinous fixation and mid-urethral slings were offered for stage III/IV apical POP and urodynamic stress incontinence, respectively. Women were followed up for 5 years. Subjective recurrence was defined as reported prolapse symptoms. Objective recurrence was defined as stage II prolapse or above. Mesh complications and patient satisfaction were reviewed.

Of 183 women who underwent transvaginal mesh surgery, 156 had ≥1 year of follow-up (mean, 50 ± 22 months). Subjective and objective recurrence rates were 5.1% and 10.9%, respectively. The mesh erosion rate was 9.6%; all affected women received local oestrogen treatment or bedside surgical excision. Three women received transobturator tension-free transvaginal tape for de novo (n=1) or preoperative urodynamic stress incontinence who did not undergo concomitant surgery (n=2); 14% of the women had de novo urgency urinary incontinence. No women reported chronic pain. Overall, 98% were 'satisfied' or 'very satisfied' with the operation.

During 50 months of follow-up, transvaginal mesh surgery for stage III/IV POP had low subjective and objective recurrence rates. The total re-operation rate was 9.6%. Most women were satisfied with the operation. Based on the risk-benefit profile, transvaginal mesh surgery may be suitable for women who have advanced POP.
