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

ABSTRACT

INTRODUCTION: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
